Coolant/Antifreeze Service in Oklahoma City, Oklahoma

Oklahoma City auto owners may know that most automotive failures in Oklahoma City, Oklahoma, are tire related, but do you know the second most common cause of vehicle failure? Nope, it's not teenagers. It is the coolant system. But if you take good care of your vehicle coolant system, it will take good care of you.

A vehicle's engine creates a lot of heat - so much heat, that if it is not properly cooled, the engine can lock up, resulting in massive damage and repair bills. But when everything is working right, your vehicle engine operates at the proper temperature and all is well. Without antifreeze in your cooling system, the water could freeze and cause vehicle engine damage. This could be very expensive, not to mention inconvenient.

The right mix of water and antifreeze protects the engine against damage from freezing and overheating. Antifreeze also protects the coolant system against corrosion that could cause the system to fail. The thing to remember is this: coolant system failure is very common, but it is also very easy to prevent. Your Oklahoma City service center knows the manufacturer's recommendations and can tell you when the coolant needs to be changed. At Car Doctor in Oklahoma City, we can perform a coolant system service.

Oklahoma City auto owners can add water or antifreeze to the bottle themselves but should be careful. First, you never want to open the radiator pressure cap. The steam could severely burn you. Second, try to get to Car Doctor in Oklahoma City immediately if your coolant is low. If that is not possible, follow the directions in your owner's manual. Third, remember that you need a proper mixture of water and antifreeze or you will damage your engine. If you make an emergency addition to your cooling system, follow-up with a service advisor at Car Doctor where they can make necessary corrections. Fourth, not all cars use the same type of antifreeze.

Oklahoma City technicians will need to check their vehicles owner's manual to make sure they use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturer’s warranty on your vehicle cooling system. If you're not sure, ask your friendly and knowledgeable service advisor at Car Doctor for guidance.

Engine Hydration for Oklahoma City Drivers: Role of Your Water Pump

The cooling system in an engine has five components: the radiator, the radiator cap, the hoses, the thermostat and the water pump. The water is literally the heart of the system. Just as your own heart keeps your blood circulating through your body, the water pump keeps coolant circulating through your engine.

The water pump is driven by a belt, chain or gear and only operates while the engine is running. It has a limited life span and sooner or later will have to be replaced. You can check your owner's manual to find out how long your water pump should last. Some can fail at only 40,000 miles (64,000 kilometers), but almost all of them fail by 100,000 miles (160,000 kilometers).

Water pumps don't gradually wear out; they fail. In other words, they're either working or they're not. A failed water pump has to be replaced.

Water pumps can fail in two ways: they can spring a leak or their bearings fail. Leaks can come from a cracked pump but usually develop at the gasket where the pump attaches to the engine.

If you hear a low-pitched grinding sound coming from the water pump, it's time for a new one. If you see coolant leaking in the area near the pump, it needs to be replaced. Also, coolant on the driveway could indicate water pump failure. Many water pumps aren't visible because they're under a plastic cover, so you may have to take your vehicle to Car Doctor to know if the water pump has failed. If your water pump is run by the timing belt, then it should be replaced when you replace the belt. Most timing belts need to be replaced at around 60,000 to 90,000 miles (100,000 to 150,000 kilometers). The labor for replacing a timing belt is about 90% the same for replacing a water pump, so it's cost-effective to take care of them both at the same time. Also, if your water pump develops a leak (if it's powered by the timing belt), you have to replace the timing belt as well since contamination by coolant fluid damages the belt. It just makes sense for Oklahoma City residents to replace both of these parts whenever either one needs it.

Replacing a water pump at Car Doctor is a vehicle care issue that almost all of us Oklahoma City residents face eventually. They don't last forever. On the other hand, we can extend the life of most of the components of our vehicle through preventive maintenance. Just as exercise and diet keep our heart healthy, regular check-ups and fluid changes will keep our vehicles healthy. Talk to your friendly and knowledgeable Car Doctor service advisor.

Coolant Service at Car Doctor

Oklahoma City residents' vehicles have to operate in a wide range of Oklahoma temperatures which requires the 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 vehicle manufacturer’s recommend different types of anti-freeze for our Oklahoma City, Oklahoma, vehicles.

There are several different 'families' of anti-freeze available to us here in Oklahoma City. Your owner's manual will tell you what kind you should use. Of course, the automotive professionals at Car Doctor will know the right kind for your vehicle.

It's important to stay on top of this because coolant system failure is the most common mechanical problem people have here in Oklahoma City, Oklahoma. Regular service needs to be done at Car Doctor 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 friendly and knowledgeable Car Doctor service advisor will know what to do. You'll be advised to replace the coolant at specified intervals.

Some recommend periodic coolant system flushes. A flush adds a cleaning step to the fluid replacement process. Again, check to see what your owner’s manual recommends.

Water Pump

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your vehicle from overheating. There are five main components to the cooling system:

  • the radiator
  • the radiator cap
  • the hoses
  • the thermostat
  • the water pump

The water pump's like the heart of your cooling system, circulating the fluid throughout your vehicle. It's a small pump that's driven by the engine; usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine's running. Water pump failure is pretty routine. We see it often at Car Doctor. Some start failing at around 40,000 miles/64,000 km, but most fail by 100,000 miles/160,000 km. Consult your owner's manual or friendly and knowledgeable service advisor at Car Doctor to see what's recommended.

Since a water pump either works or it doesn't, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It's possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can Oklahoma City drivers tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump, it's got a problem. If you can see coolant in that area, you've got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can't see the water pump. Look for coolant on the driveway. If you see some, have Car Doctor check it out.

Most timing belts need to be changed at 60,000 miles/97,000 km – some longer. It's a good idea to change your water pump at the same time if it's one of those that's driven off the timing belt. To start with, 90% of the work's already done with the timing belt change. And if you don't and develop a leak later, you'll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

Car Doctor can replace a failed water pump with a brand spankin' new one or with a rebuilt pump. Rebuilt will save you some money, but ask your service advisor at Car Doctor what he thinks. Don't feel too bad if your water pump gives out. They will all wear out eventually. We can get you back on the road and on with your life.

Cooling System Components

Today we want to talk about a system in our vehicles – the cooling system. It's one of those things that Oklahoma City auto owners don't give much thought to until it fails and then they're stranded by the side of a road in Oklahoma.

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 Oklahoma City drivers take care of their cooling systems, they can keep working for the life of their car.

Here at Car Doctor in Oklahoma City, 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, radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.

It sounds complicated, but we Oklahoma City residents don't have to be experts – we can leave that to our friendly and knowledgeable service advisor at Car Doctor. But, having an overview will help us remember how to take care of your car's cooling system.

Most Oklahoma City folks would be surprised to know that burning fuel in your engine produces up to 4,500 degrees F/2,500 degrees C 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 vehicle 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 cash on replacing the belts and water pump is much less than the cost of repairing the extremely massive damage that can be done when an engine seizes.

There's another little known but important 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 is enough to 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.

The team at Car Doctor can check your cooling system and make any necessary adjustments or repairs. Give us a call.

Cool Running in Oklahoma City

Unless you live in Death Valley, you really don't hear much any more about cars overheating. That's because cooling systems in vehicles have been much improved. That doesn't mean you can't overheat your vehicle engine, though. Without proper preventive maintenance, you could still find yourself on the side of the road in Oklahoma City waiting for your vehicle engine to cool down.

When you service your cooling system at Car Doctor, your technician will check the condition of the coolant. It can become corrosive over time, which can damage a radiator — leading to an overheated engine. Changing the coolant periodically is good vehicle care. Your vehicle owner's manual can give you guidelines on how often to replace it.

If your engine overheated, your friendly and knowledgeable service advisor will also check your coolant system for leaks. Check the vehicle radiator for cracks and the radiator hoses for leaks. He'll also check your water pump. They don't need to be replaced on a regular schedule, but they do need checked regularly. They can and do wear out.

The water pump is a critical component of your vehicle cooling system. It pumps the coolant to keep it circulating through the engine. The coolant is cooled in the radiator, then it travels through the engine, where it absorbs heat, then it returns to the radiator, where it releases the heat. And so on. But a water pump is something of a misnomer. The fluid pumped through your vehicle cooling system is not just water. It also contains coolant, which is actually poisonous. You should never consider your radiator as an emergency water supply.

There are many types of coolant. It varies from vehicle to vehicle, and using the wrong kind could damage your engine. Your service advisor will know which kind your vehicle's manufacturer recommends. The team of automotive professionals at Car Doctor is always a good source for auto advice. We've been providing quality automotive services at our convenient location in Oklahoma City for years.

At Car Doctor, we help you keep your cool which will keep you in the driving lane.

Smart Oklahoma City Drivers Protect Against Overheating

Engines get hot when they run. This heat can build up and damage vital engine parts, so engines need a cooling system to keep them running. Cooling system failure is the most common mechanical failure in vehicles. This is unfortunate, because these failures are usually easy for Oklahoma City drivers to prevent.

The radiator is the best-known and most recognizable part of the cooling system. Hoses filled with coolant (also known as antifreeze) connect the radiator to the engine. The coolant draws heat from the engine and then flows to the radiator. Air passing through cooling fans on the radiator cools the coolant. The coolant then cycles back into the engine to start the process over again.

The most critical component of the cooling system, however, is the coolant itself. A mixture of water and coolant/antifreeze helps keep it both from freezing and from boiling away. Either can result in serious engine damage.

Different engines require different types of coolant/antifreeze. The owner's manual will list what kind a vehicle requires. Using the wrong type or mixing different types of coolant/antifreeze may void the warranty on the cooling system and may damage it as well.

Insufficient coolant can lead to engine failure. Coolant levels need to be checked regularly and topped off as necessary. If coolant levels drop quickly or consistently, the cooling system should be inspected for leaks. Coolant/antifreeze contains additives that protect the radiator and other coolant components from rust, scale and corrosion. Over time, these additives are depleted, so it is necessary for Oklahoma City drivers to replace coolant at specified intervals. Changing coolant should be part of routine preventive maintenance for any vehicle.

This service is often ignored, though, since old coolant still cools the engine. Vehicle owners don't realize there is a problem until the system fails. They are left with major repairs and possibly a damaged engine, which could have been prevented with a cooling system service at Car Doctor in Oklahoma City.

If your vehicle sends a warning message to check its coolant or if the temperature gauge is reading in the red or hot zone, then the cooling system needs serviced. This service is critical and should not be put off since the potential for damage is high.

In an emergency situation, water or antifreeze can be added to your vehicle so that it can be driven to a service center for proper car care. For this reason, your owner's manual contains instructions for how to top off insufficient coolant – allow 45 minutes for the engine to cool before attempting to add coolant or water. However, the fluid should be added to the coolant overflow bottle, not to the radiator itself. Removing the radiator pressure cap can result in severe burns.

Topping off in an emergency, however, does not fix the problem. The vehicle should immediately be taken to Car Doctor in Oklahoma City where they can inspect the cooling system, repair any leaks and clean it if necessary. They can identify what caused the emergency situation in first place and ensure it doesn't happen again.

Regular maintenance of a vehicle's cooling system is just good auto advice for Oklahoma City drivers. Cooling system service is relatively inexpensive and doesn't take long at Car Doctor. Lack of it, however, can put a vehicle in the scrap heap.

Talk to our service advisor at Car Doctor for more information.

Coolant/Antifreeze Service at Car Doctor

Anyone who drives a car in Oklahoma City knows that engines get hot when they run. But did you know that engines need to be cooled to keep running? Heat inside an engine can cause the metal parts to expand, which can seize up an engine and make it stop running. It can even ruin the entire engine! Good vehicle care requires keeping its cooling system in good condition.

A vehicle's cooling system circulates water and antifreeze (coolant) through the engine where it absorbs heat. It then flows to the radiator where the water and antifreeze are cooled by the air that flows over the radiator. Then it circulates back into the vehicle's engine to absorb more heat.

Why shouldn't Oklahoma City auto owners just use water? Because water boils at temperatures that are often reached inside of an engine. Steam won't cool your vehicle engine and is hard to contain within the cooling system. The antifreeze keeps the water from boiling.

So why do we call it antifreeze? Shouldn't it be antiboil? Truth is, the antifreeze performs another critical task. Water freezes in cold Oklahoma weather. That would spell disaster for your vehicle's engine. So antifreeze also keeps the water in your cooling system from freezing in all but the most extreme cold. Pretty neat stuff!

Taking care of your cooling system is part of good preventive maintenance for your vehicle. Oklahoma City area drivers should check coolant level often and regularly inspect your cooling system for leaks.

That is just good auto advice. Your vehicle's manufacturer has maintenance requirements for draining and replacing engine coolant. Consult your owner's manual or ask your friendly and knowledgeable Car Doctor service advisor for these recommendations, as they vary widely among vehicles.

Keep Your Cool in Oklahoma City

Oklahoma City drivers rely on their vehicle's coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your vehicle engine and absorbs heat. The mixture then flows out to the radiator where it's cooled by air flowing over the radiator. From there the coolant/water mix circulates back through the engine to absorb more heat.

There's a reason we mix coolant and water. Water alone actually does a good job transferring heat from the engine. The problem is that water boils at a temperature that's easily reached inside your vehicle's engine, so it can turn to steam which does not conduct heat as well and is harder to contain.

Also, if it's freezing outside in Oklahoma City, the water in your engine could freeze while your vehicle is sitting out in the Oklahoma cold.

So, if you remember your high school chemistry, you'll know that a mixture has both a higher boiling point and a lower freezing point than either component alone.

Coolant, or antifreeze, is specially formulated to keep your engine safe in a wide range of environmental and operating temperatures in and around Oklahoma City.

Whenever your vehicle is running, the coolant in the cooling system is working to keep your engine from overheating. When it's cold outside, the coolant acts as antifreeze to keep the fluid from freezing in your engine.

All that exploding fuel in your engine creates a lot of heat. Without coolant, the metal vehicle engine parts would expand so much that the engine would seize up and stop running. The parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole vehicle's engine is ruined and has to be junked.

This is why it is critical that Oklahoma City drivers check coolant levels frequently and have their vehicle's cooling system inspected for leaks. Also your vehicle has a maintenance requirement for draining and replacing your coolant. These recommendations can vary widely, so check your owner's manual or ask us at Car Doctor in Oklahoma City.

The reason Oklahoma City drivers need to change the coolant is that it has additives in it to protect the cooling system. As you can imagine, with all the heat, the cooling system's a pretty harsh environment. The additives keep the fluid from becoming corrosive and damaging the radiator and other vehicle cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.

Many Oklahoma City auto owners ask our advisors at Car Doctor why there are different colors of antifreeze. It is very important that you use the correct type of antifreeze. The different types of antifreeze – or coolant – are different colors so you don't mix them up.

They use different materials to make the cooling system, and they require different types of antifreeze to protect them.

So check with us at Car Doctor in Oklahoma City or your owner's manual for the right kind because using the wrong coolant can void the warranty for your vehicle cooling system.

Keeping Your Engine Cool in Oklahoma City, Oklahoma



The cooling system keeps Oklahoma vehicle's engines from overheating while they are driving around Oklahoma City. Its job is to move heat away from the engine. Let's talk about the various components of the system and how they make this happen.

The radiator is the part most Oklahoma City drivers associate with the cooling system. Coolant flows through the radiator which has fine cooling fins that draw the heat out of the coolant and dissipate it into the air. To make sure there's enough airflow over the radiator, a fan pulls air over the cooling fins even when the vehicle is idling.

In some vehicles, the fan is powered by the serpentine belt. On others, an electric motor runs the fan. Electric fans turn on and off as needed. You may have heard the fan kick on shortly after you turn your vehicle off. The sensor has determined that the engine needs a little help cooling down to a safe temperature.

A hose connects the radiator to the water pump. The water pump pushes the water into the vehicle engine block. Now the engine block and cylinder heads have passages for the coolant to pass through without getting into the oil or the combustion chamber. In the automotive community, these passages are referred to as the "water jacket."

While the coolant is passing through the water jacket, it absorbs heat from the vehicle engine on its way to the radiator for cooling. Between the engine and the radiator is a gatekeeper called the thermostat. The thermostat's job is to regulate the temperature of the engine just like your home thermostat regulates the temperature in your house. It gets your engine up to the correct operating temperature and then keeps it from overheating.

When you first start the engine, it's very cold and needs to warm up. So the thermostat blocks the flow of coolant to the radiator. As the engine warms up, the thermostat starts to let coolant flow through the system.

The final component the team at Car Doctor wants to point out is the overflow reservoir. This bottle is designed to hold some of the coolant. It'll have a mark that indicates whether or not you have enough coolant. This is where you should add coolant if you just need to top it off.

Caution: never open the reservoir or the radiator cap when the car's hot. The cooling system is pressurized, and opening those caps while it's hot can cause hot coolant and steam to escape resulting in serious burns.

Cooling system failure is the most common mechanical failure in vehicles around Oklahoma City, Oklahoma. At Car Doctor, we can do a periodic inspection of the components for  leaks, loose connections and weakening hoses.

Your vehicle manufacturer has also specified a cooling system service interval. With a cooling system service at Car Doctor in Oklahoma City, the old coolant is replaced with correct clean fluid that contains the additives required to prevent corrosion. The additives are depleted over time and you need fresh fluid for adequate protection. Your radiator pressure cap should be replaced at this service as well.
