Castle Rock car owners know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine’s cylinders. This is the function of the fuel injectors.
There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.
Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.
For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower.
Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.
Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.
Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.
When fuel injectors get dirty, their precision drops off. The spray pattern won’t be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and gas mileage for Castle Rock auto owners as well as delivering less power to the engine.
Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we’re talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.
So keeping your fuel injectors clean is just good auto advice for Castle Rock motorists. The best way to do this is to change your air and fuel filters regularly and practice other habits of good car care and preventive maintenance at Double “D” Auto Repair, Inc. in Castle Rock. Cleaning additives in your fuel can also help.
If you do end up with gum or varnish in your fuel system, you’ll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.
Brakes really aren’t optional equipment. And taking care of them isn’t optional either.
A regular brake inspection is on every car’s maintenance schedule. An inspection will check your brake system and let you know if there are any problems. Of course, if you’re having trouble with your brakes, get your car into a Castle Rock or Franktown service center right away. And watch out for these problems:
Low or spongy brake pedal
Hard brake pedal
A brake warning light that stays on
Constantly squealing or grinding brakes
Vibrations or clunking sounds when you apply your brakes
There are two types of brakes: disc and drum. Disc brakes have a rotor that’s attached to the axle. Calipers straddle the rotor, kind of like the brakes on a bicycle. Drum brakes are more common on back wheels. Pads, called shoes, push against the inside of the drum to slow the vehicle.
There are several things that need to be serviced on the brake system. First, the brake pads and shoes wear out with use, and become too thin to really help. If the brake pads wear away completely you can damage the rotors. The calipers can grind grooves in the rotor. Then the rotor must either be resurfaced or replaced and that can be expensive. But putting it off is dangerous because your vehicle won’t stop as quickly. Sometimes rotors warp or crack and must be replaced.
Brake fluid is also important. When the brakes are applied, the pressure in the fluid activates the brake pads or shoes. Not enough fluid, not enough pressure to brake properly. Also, water builds up in the brake fluid over time, which leads to corrosion, leaks and brake damage, and with hard use, the brakes could severely fade or even fail. You should change the brake fluid when your manufacturer recommends it.
There are different grades of brake pads. There are regular, metallic and ceramic – higher grades cost more, but give better braking performance and smoother operation. It’s OK to upgrade your brake pads. But, never use a grade that’s lower than what the manufacturer recommends.
Be sure to properly maintain your brakes because it’s a lot cheaper than paying your nearest Denver area body shop after an accident.
Most Castle Rock and Sedalia motorists want to save on gas and seek our advice on improving fuel economy. At Double “D” Auto Repair, Inc., we are frequently asked, however, if it is really worth the extra effort. Just how much money can Sedalia drivers actually save?
The US government has a website dedicated to helping us use less fuel. It presents the cost savings in a way Sedalia auto owners can relate to and is relevant for all vehicles. Let me give you an example: Having your SUV engine properly tuned, can save up to 4%. If you’re paying three-fifty for a gallon of gas, you could save fourteen cents a gallon.
In today’s Double “D” Auto Repair, Inc. article, we’re focusing on the things you can do to improve your SUVgas mileage driving around Colorado. We’ll tell you the potential savings per gallon of gas at three dollars and fifty cents, and we’ll show a chart that also shows the savings at three and four dollars.

The last thing we’ll talk about is excess weight. Our SUVs tend to accumulate a lot of things and the weight adds up. Clear out the trunk and only haul stuff when you really need it. For every one hundred pounds you can save two percent or seven cents a gallon.
Sorry honey, your brother can’t come with. It’d cost an extra thirty cents a gallon.
We live in such a disposable society. It’s amazing all the stuff we throw away. New stuff comes out so fast, we just toss the old and move on. In the old days people were real sticklers about taking care of their things. If something got lost or ruined by neglect, tough – they had to do without. Most people couldn’t afford new cars very often, so they had to make them last as long as they could.
It’s a good thing that cars are more reliable these days. They just don’t break down as often. And the good news for us Colorado penny pinchers is that a modern car can easily go 200,000 miles/320,000 km with proper care. The engineering and the manufacturing quality is tremendous. The missing ingredient is us Castle Rock car owners making sure we follow the manufacturer’s recommended maintenance schedules.
Every time you go a couple thousand extra miles between an oil change, you have created an opportunity for sludge to be formed and clog passages. Then some parts don’t get properly lubricated and they start to wear out faster. Skip a cooling system service, and the corrosion inhibitors become depleted, and the radiator starts being damaged – one step closer to a failure. Same thing is true for transmission service, power brakes, fuel system cleaning – really everything on your schedule.
It is probably even more important for older vehicles. Those engines and other systems have had more time to get dirty, so they are a bit more stressed anyway. But it is never too late to get back on track with your maintenance and to hold off further damage.
And it really does start with the oil change. When you get a full service oil change they top off all your fluids and check for other items that are on your maintenance schedule. It’s like your safety net. Go in for an oil change on time, and let your service advisor help you keep track of the rest.
Some things are going to wear out along the way, things like alternators, water pumps, etc. But fixing those at Double “D” Auto Repair, Inc. is cheaper than a new car payment. And taking care of problems early means they have less time to mess with other things. It is like having high cholesterol – you don’t want to wait for a heart attack before you address it.
A fuel injector is a valve that delivers fuel to a vehicle’s engine. It has to deliver the precise amount of fuel, to precisely the right place, precisely when the engine needs it. The fuel also has to be mixed with air before it can burn in the engine.
Fuel injectors are engineered to spray fuel in a specific pattern into the engine. (The pattern varies by engine type and design.) In order to achieve these spray patterns, the fuel must be pressurized.
The pressure in a fuel injection system varies depending on its type. Many gasoline engines use port injection systems, which operate with a pressure of 60 pounds per square inch. Newer direct injection systems operate at 10 to 30 times that pressure. Some diesel passenger vehicles have fuel injectors that operate at 30,000 pounds or more per square inch.
Vehicles have one fuel injector for each cylinder in the engine. Your vehicle’s control computer constantly monitors the engine and various sensors in the vehicle and adjusts the fuel injectors accordingly so that they can deliver the proper amount of fuel to the engine. As you can see, fuel injectors are a sophisticated and vital part of your vehicle’s engine.
Because fuel injectors are such precision instruments, dirt and contaminants are a serious detriment to their performance. When an injector gets gummed up, it affects the pressure, pattern and timing of the fuel delivery. The result is a decrease in gas mileage and loss of engine performance.
So it’s critical to keep your fuel injectors clean. That starts with keeping the fuel in your tank clean. High-quality fuel contains detergents and additives that help clean your engine. Brand-name Colorado fuel companies also deliver a more consistent quality of fuel than do bargain stations in the Denver area.
The second way to keep your injectors clean is to keep your fuel filter clean. This filter screens dirt and rust out of the fuel as it travels from the tank to the engine. If the filter clogs up, fuel will bypass it and carry its load of dirt into the engine.
Check your owner’s manual or Double “D” Auto Repair, Inc. in Castle Rock to find out how often you should change your fuel filter. This should be part of your regular preventive maintenance. Also, remember that if you use bargain-brand or low-grade fuels, or if you drive an older vehicle, your filter will need to be changed more often.
You can also purchase cleaners that will protect your fuel injectors. These cleaners are added to the fuel tank. They work best at preventing build-up in your fuel injectors and can clean up small amounts of carbon, gum and varnish. But they won’t be able to clean a fully gummed-up injector. Read the labels before using any of these products for full directions on their use.
If your fuel injectors are gummed up, you can get a professional deep cleaning service at Double “D” Auto Repair, Inc. in Castle Rock that will result in better gas mileage and improved vehicle performance.
Good car care will prevent serious damage to your fuel injector system. And this is one system that you want to keep in perfect condition.
Today we want to talk about a very important system in our cars – the cooling system. It’s one of those things that you don’t give much thought to until it fails and then you’re stranded by the side of the road.
Cooling systems fail more often than any other mechanical system – usually because of neglect. Don’t you hate it when something breaks, and you could have done something to prevent it?
The good news is that if you take care of your cooling system it can keep working for the life of your car.
Here at AutoNetTV, we emphasize preventive maintenance services like replacing your coolant according to the factory schedule. But the various parts that make up the cooling system need attention too. The major components of the cooling system are the water pump, freeze plugs, the thermostat, the radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.
It sounds complicated, but we don’t have to be experts – we can leave that to our Honest service technicians at Double “D” Auto Repair, Inc.. But, having an overview will help us remember to take care of our cooling systems.
Most people would be surprised to know that burning fuel in your engine produces up to 4,500 degrees of heat. And all that heat has to be dealt with. If the heat can’t be drawn off the engine, the pistons will literally weld themselves to the inside of the cylinders – then you just have to throw the engine away and get a new one. That would cost thousands of dollars.
Now the water pump is what forces the coolant through passages in the engine to absorb heat. The pump is driven by a belt that needs replacement from time to time. And the water pump will eventually wear out and need to be replaced. Spending some money on replacing the belts and water pump is much less than the cost of repairing the massive damage that can be done when an engine seizes.
There’s another little part of the coolant system that protects the engine. It’s called a freeze plug. If you remember from high school chemistry, water expands when it freezes. In very cold areas, the coolant can actually freeze when the vehicle is left sitting.
It is hard to believe, but the expanding frozen coolant can actually crack the engine block. The freeze plugs fit into the engine block. They fit tight enough to withstand the pressure of a running engine, but can expand or pop out if the coolant freezes. These little things save a lot of engine blocks.
That brings up a good point. An engine has to work in all kinds of temperatures – extremely hot as well as very cold. How does the cooling system adapt to external temperatures as well as varying operating conditions?
Well, it’s much like the way you keep your house at a comfortable temperature all year round – with a thermostat. The thermostat in your car controls how much coolant flows through your engine. When the engine is cold, it restricts coolant flow until the engine comes up to an efficient operating temperature. Then it starts opening up to move more coolant to keep the temperature within a specified range.
The thermostat needs to be replaced from time to time as well. It’s easy to diagnose a failed thermostat and is fairly inexpensive to replace. We can do this for you at Double “D” Auto Repair, Inc. in Castle Rock, just give us a call: 303-688-4510. Now we’ve been talking about all this heat we’ve got to get rid of, but haven’t really talked about where it goes. That’s where the radiator comes in. The hot coolant passes through the radiator. Air flows past the cooling fins and cools the coolant.
The radiator has two tanks that hold coolant: sometimes one the top and bottom or one on either side. If you have an automatic transmission, one of the tanks will also contain a second tank that cools the transmission fluid. Large SUV’s and trucks often have a separate transmission cooler. So when you drive around Castle Rock, the air is forced past the radiator. But driving doesn’t produce enough air flow. So the radiator has cooling fans that force fresh air over the radiator. These fans may be powered by a belt or by electric motors.
Now, you also have something called a heater core. The heater core is like a mini radiator. A small fan blows air over the heater core and into the passenger compartment of your vehicle. That’s how you warm your car when it’s cold out.
Next is the radiator cap. With most newer cars around Castle Rock, you never remove the radiator cap, except to replace it. You add coolant through the overflow tank. The radiator cap is also called a pressure cap, because its job is to maintain pressure in the cooling system.
High pressure raises the boiling point of the coolant, so it cools more effectively even in very demanding conditions. That is why you need to replace the cap from time to time. They recommend changing it out every time you replace your coolant.
Coming back to the overflow tank, it is needed because when the coolant gets hot it expands and the overflow holds the extra volume. The tank helps maintain the proper level of coolant and keeps air out of the system. You should never open the radiator cap or over flow tank when the engine is hot. This could lead to serious burns.
What else do we need to do to keep our cooling systems working well? Well, there are the hoses that hook all of these pieces together. They’re obviously very tough to deal with the pressure and high temperatures. But they do get worn. Sometimes they get spongy from the heat. Sometimes they lose their connection to the radiator, water pump, etc. It’s a great idea to have your Castle Rock service center inspect your hoses at least once a year and replace them, if needed, before they break.
Double “D” Auto Repair, Inc. can help you check your cooling system and make any necessary adjustments or repairs. Give us a call at 303-688-4510.
Everyone in Castle Rock Colorado does our best to budget for scheduled vehicle maintenance. What’s hard is unexpected repairs. The truth is that our vehicles can stay on the road longer than ever before with proper maintenance. That’s because of improved vehicle design and manufacturing quality. But some of those same improvements also lead to higher repairs costs.
Let’s take the fuel pump. Previous generations were often stranded by the side of the road by vapor lock. This occurred when the gas vaporized between the gas tank and the fuel pump. Fuel just stopped flowing.
You had to sit and wait until the car would start again. To alleviate the problem, fuel pumps are now located inside the gas tank. This is a great solution, but when the fuel pump fails, it’s a much more expensive proposition to replace it.
Sealed wheel bearing assemblies are another example. These wheel bearings can’t be serviced – you just have to replace the entire assembly when it starts to fail. That costs several times as much as service on non-sealed bearings.
So we all benefit in Castle Rock Colorado from design improvements, but we need to plan for repairs down the road.
There’s a tool that can be found on Edmunds.com that you can use to prepare your service and repair budget.
Let’s suppose you have a 2003 Toyota Camry – a very popular car in Castle Rock Colorado. It’s now paid for and you’d like to keep it running for the next three years. You can go to Edmunds’ True Cost to Own calculator and enter your vehicle’s data. The calculator will provide estimates of what it’ll cost to service and repair your vehicle over the next five years. The estimate is based on where you live in or near Castle Rock Colorado, manufacturers’ recommendations and repair experience for your particular model.
Of course these are just estimates – there’s no way to predict what’ll actually happen to the car in your driveway, but it’s a good starting point.
The calculator also has estimates for depreciation, financing, insurance, taxes and fuel costs.
Let’s focus on maintenance and repair. This table shows that the average monthly cost of maintenance and repairs is eighty-three dollars. That may sound like a lot, but compare it to a new car payment.
So if you set aside eighty-three dollars a month, you’d go a long ways towards taking care of routine maintenance and being prepared for the unexpected repairs that arise.
Of course, you can’t predict when something will go wrong or what it’ll cost, but at least you have a reasonable target to shoot for.
Some people around Castle Rock Colorado are afraid of what can go wrong with their older car so they buy a new one. That’s fine if you really want a new car, but if you properly maintain your older vehicle, you’ll save a lot of money on new car payments and insurance. It just makes good economic sense.
Get with your Castle Rock Colorado service advisor at Double “D” Auto Repair, Inc. and work out a plan for keeping your vehicle on the road.
Don’t you hate it when you hear that squeal from under the hood when you’re zipping down a busy Denver highway? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator – which charges the battery; the water pump – which cools the engine; the air conditioning and the power steering pump. All pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components.
Serpentine belts are amazingly tough. They can last for years and go for tens of thousands of miles. Like all moving parts, however, they eventually wear out. If your belt breaks while you are driving, everything will come to a halt within minutes. You need to stop the car immediately or it will overheat, potentially causing major engine damage. You can be sure that it won’t happen at a convenient time or place. (As if there was a convenient time or place!) You might even need to get your car towed to your nearest Castle Rock car repair shop. It’s no wonder that auto manufacturers recommend a belt replacement on schedule. It’s one of those “have-to’s.”
Castle Rock auto owners who hear a squeal when accelerating or a slow, slapping sound at idle, should have their serpentine belt looked at. Your service specialist at Double “D” Auto Repair, Inc. in Castle Rock will visually inspect your belt to see if it needs to be changed sooner than scheduled. If the belt has more than three or four cracks an inch, has deep cracks that penetrate half the depth of the belt, is frayed, is missing pieces or has a shiny glazed look, it needs to be replaced regardless of age or mileage.
Serpentine belt replacement is relatively inexpensive, especially compared with the cost and inconvenience of being stranded or getting a disabled vehicle back to Double “D” Auto Repair, Inc. for repairs.
You’re mom was right: an ounce of prevention really is worth a pound of cure.
One Castle Rock automotive service issue that doesn’t get much attention is driveline service. Drivelines don’t get talked about very much around Castle Rock, but they’re very important. First let’s define what the driveline is:
Taking a small step back, the power plant is comprised of the engine and transmission. The driveline starts there and includes all of the components that transfer power from the transmission to the wheels.
That’s not really a lot of components, but they handle the full force of the engine. Without the driveline you’re not moving. So we need to take good care of it. The driveline components differ depending on whether your vehicle has front wheel drive, rear wheel drive, all wheel drive or four wheel drive. For purposes of our discussion, we’re going to have to over simplify a bit.
If you are ready to have your drive train looked at, give us a call: Double “D” Auto Repair, Inc. 1235 Caprice Drive Castle Rock, Colorado 80109 Call Us at 303-688-4510
Let’s start with front wheel drive. The point where the transmission stops and the driveline begins is a little blurred with front wheel drive because the transaxle houses both the transmission function and the differential function. The half shafts that send power to each front wheel, come out of the transaxle. The shaft is connected to the wheel by a constant velocity, or CV, joint. The CV joint is protected from dirt and water by an airtight, flexible rubber boot.
So, driveline service would include properly servicing the transaxle and inspecting the CV boot to see if it’s torn or loose. If it is, it needs to be replaced and the CV joint inspected for damage. Repairs may be in order. Besides visual damage to the airtight CV boot, you might hear a clicking noise when turning. Recommended maintenance for the transaxle and CV joints will be spelled out in your owner’s manual or check with your Castle Rock service advisor.
On to rear wheel drive. The driveline for a rear wheel drive vehicle starts with the driveshaft – that long tube that connects the transmission with the differential on the rear axle. Some vehicles in Castle Rock have a two piece drive shaft. The shafts are connected to the transmission and the differential with big universal joints. You’ve probably heard the term ‘u-joints‘. These joints can wear out, just like the CV joints in front wheel drive vehicles. You may hear some clunking or feel a jolt when shifting into drive or reverse – if you do, get your driveline inspected.
The differential on the rear axle sends power out to each rear wheel through half shafts in the axle. The differential fluid needs to be drained periodically and replaced with clean fluid. When the seal on the end of the axle is damaged or leaks, the axle will need to be serviced. The routine maintenance item here is differential service. Be sure to check your owner’s manual or Castle Rock service advisor for intervals.
Now let’s go on to all wheel drive. Remember that the difference between all wheel drive and four wheel drive is that an all wheel drive vehicle is essentially providing power to all of the wheels all of the time. The vehicle may be able to shift more of the power to the front or to the back depending on where you need traction. All wheel drive vehicles are designed to work well on dry pavement. Even some high-end sports cars from makers like Lamborghini and Porsche have all wheel drive.
Some all wheel drive vehicles are designed to work well off-road, but all hard-core rock crawlers are four wheel drive. These guys thrive in mud, sand, rocks and hills – but they don’t work well on dry pavement when they’re in four wheel drive. So they have the option to shift to rear wheel drive only on dry pavement.
Most all-wheel drive vehicles are very similar to front wheel drive when it comes to the front end. They also have a center differential that transfers power to the rear differential. Connecting it all is a shaft from the transaxle to the center differential and another from the center differential to the rear differential. So all of the normal front wheel drive service is required as well as service to the center and rear differentials.
Four wheel drive can be thought of as a rear wheel drive vehicle that can also send power to the front axle. There’s a transfer case in the middle of the vehicle that can be shifted to send power through a drive shaft to a differential on the front axle. So you need differential service for the front and rear differentials and for the transfer case as well.
The bottom line is that the maintenance schedules are in your owner’s manual. Your Castle Rock service advisor can answer any questions you’ve got. If this is the first time you’ve heard some of this stuff – it’s time to ask someone at Double “D” Auto Repair, Inc. if any of it needs to be done now.
Castle Rock drivers’ cars have to operate in a wide range of Colorado temperatures which requires our engine coolant to be able to perform ‘no matter what’. Think for a moment about the environment where the coolant does its thing. Very hot, high pressure, corrosive…
And all the while, it has to protect the components of the cooling system from corrosion. These components are made from steel and aluminum, plastics and rubber. The coolant has to be formulated to protect against corrosion for all of these different materials. That’s why auto makers recommend different types of anti-freeze for our Castle Rock, Colorado vehicles.
There are several different ‘families’ of anti-freeze available to us here in Castle Rock, Colorado. Your owners’ manual will tell you what kind you should use. Of course, the automotive professionals at Double “D” Auto Repair, Inc. will know the right kind for your car.
It’s key to stay on top of this because coolant system failure is the most common mechanical problem people have here in Castle Rock, Colorado. Regular service at Double “D” Auto Repair, Inc. needs to be done to avoid failures and also to keep your warranty in place.
While the specifics of the service required may vary from vehicle to vehicle, your Honest Double “D” Auto Repair, Inc. service professional will know what to do. You’ll be advised to replace the coolant at specified intervals.
Some auto makers recommend periodic coolant system flushes. A flush adds a cleaning step to the fluid replacement process. Again, check to see what your Castle Rock service professional recommends.
Someday, you may have to deal with an overheating problem, so you need to know what to do if your coolant temperature warning light comes on or your temperature gauge is in the hot zone.
Now, overheating can be very pricey. Castle Rock drivers can literally melt down their engine and have to replace the whole thing. So don’t ignore warning signs.
First turn off the air conditioner. This will lower engine temperature right away. Next, crank up your heater to maximum heat and run the fan at high speed. You might need to roll down the windows, but this will take a lot of heat off the engine. Pull over as soon as you can safely do so, especially if you are stuck in slow-moving traffic, and shut the car off. It may take as much as 45 minutes for the engine to cool to the point that it’s safe to operate the car again.
If you need to add water or antifreeze, be sure to wait until the car cools down. Opening the radiator cap or even the overflow bottle when the coolant is hot and under pressure may result in serious burns.
After the engine has cooled for 45 minutes or so, look to see if the coolant is low in the overflow tank. If so, you can cover the overflow tank cap with a large cloth and open the lid. Then start the engine and pour in some water or antifreeze. Pouring it in when the car is running will circulate the new, cool fluid with the warmer fluid in the engine and avoid engine damage.
Of course, overheating is a serious problem and you need to get it fixed right away. Double “D” Auto Repair, Inc. can make sure the coolant is right before you drive home.
Those spring and winter inspections really come in handy when they head off a cooling system problem. And don’t forget that severe service driving conditions, like towing or hot, dusty driving around Castle Rock, Colorado, mean that you’ll need to service your coolant more frequently.
At AutoNetTV, we suggest that you have Double “D” Auto Repair, Inc. inspect your coolant system to find small problems before they become big, and to change belts and hoses before they fail. After all, we don’t want you to lose your cool out there in Castle Rock, Colorado.
