Category Archives: Cooling System
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 sedan engine, though. Without proper preventive maintenance, you could still find yourself on the side of the highway in Birmingham BDG waiting for your sedan engine to cool down.
When you service your cooling system at Birmingham BDG, your service advisor 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 car care. Your sedan owner’s manual can give you guidelines on how often to replace it.
If your engine overheated, your courteous service specialist will also check your coolant system for leaks. Check the sedan 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 a diagnostic examination regularly. They can and do wear out.
The water pump is a critical component of your sedan 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 sedan 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 specialist will know which kind your vehicle’s manufacturer recommends. The team of automotive professionals at Birmingham BDG is always a good source for auto advice. We’ve been providing quality automotive services at our convenient location in Birmingham BDG for 10 years.
Keeping your cooling system in good repair will help keep your engine running well, and keep you out of the Clay repair shop. This means that a regular cooling system inspection should be on your schedule for routine preventive maintenance of your vehicle. Your owner’s manual will tell you how often you need to do this. It varies depending on what kind of car you drive, what type of driving you do and where you live in AL.
At Birmingham BDG, we help you keep your cool which will keep you in the driving lane.
Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system:
- the radiator
- the radiator cap
- the hoses
- the thermostat and
- the water pump
The cooling system is essential for Birmingham BDG car owners. It circulates coolant through the radiator and your engine to protect your sedan from overheating. There are five main components to the cooling system:
the radiator cap
the thermostat and
the water pump
The water pump’s like the heart of your cooling system, circulating the fluid throughout your sedan. 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 Birmingham BDG. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your auto maker’s owners’ manual or courteous Birmingham BDG service advisor 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 Birmingham BDG car owners 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 your Birmingham BDG technician check it out.
Most timing belts need to be changed at 60,000 miles – 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.
Birmingham BDG drivers can replace a failed water pump with a brand spankin’ new one or with a rebuilt pump. Rebuilt will save you some cash, but ask your courteous Birmingham BDG tech what he thinks. Don’t feel too bad if your water pump gives out. They will all wear out eventually. Your Birmingham BDG service professional can get you back on the road and on with your life.
Birmingham BDG motorists rely on their car’s coolant system to keep their engine cool. Coolant (also called antifreeze) mixed with water flows through your sedan 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 sedan’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 Birmingham BDG, the water in your engine could freeze while your vehicle is sitting out in the AL cold.
So, if you remember your Birmingham BDG 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 Birmingham BDG.
Whenever your sedan 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 sedan engine parts would expand so much that the engine would seize up and stop running. The expensive parts could be broken or warp so badly they would have to be replaced. It could even be so bad that the whole sedan’s engine is ruined and has to be junked.
This is why it is critical that Birmingham BDG drivers check coolant levels frequently and have their sedan cooling system inspected for leaks. Also your sedan vehicle manufacturer 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 Birmingham BDG in Birmingham BDG.
The reason Birmingham BDG car owners 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 sedan cooling system components. Over time, the additives are depleted and the coolant just has to be replaced.
Many Birmingham BDG auto owners ask Birmingham BDG 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.
The vehicle manufacturers use different materials to make the cooling system, and they require different types of antifreeze to protect them.
So check with us at Birmingham BDG in Birmingham BDG or your owner’s manual for the right kind because using the wrong coolant can void the warranty for your sedan cooling system.
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 courteous service technicians at Birmingham BDG. 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 Birmingham BDG in Pinson, just give us a call: 1.800.LET.NAPA. 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 Pinson, 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 Pinson, 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 Pinson service center inspect your hoses at least once a year and replace them, if needed, before they break.
