Category Archives: Cooling System
Anyone that drives a car in Tupelo 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 car care requires keeping your pickup 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 pickup’s engine to absorb more heat.
Why shouldn’t Mooreville car owners just use water? Because water boils at temperatures that are often reached inside of an engine. Steam won’t cool your pickup 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 MS weather. That would spell disaster for your pickup’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 pickup. Tupelo car owners should check coolant level often and regularly inspect your cooling system for leaks.
That is just good auto advice. Your pickup’s manufacturer has maintenance requirements for draining and replacing engine coolant. Consult your owner’s manual or ask your knowledgeable Tupelo NAPA AutoCare Centers tech for these recommendations, as they vary widely from among auto manufacturers.
Changing your coolant is also part of good preventive maintenance. Water is great at collecting all kinds of dissolved substances, especially when it’s hot. Water circulating through an engine picks up dirt, debris, pollutants, and other stuff. It actually becomes corrosive over time. This can damage engine parts and your radiator.
Replacing your coolant regularly keeps the pickup cooling system functioning well and doesn’t allow it to sneakily become the cancer that wipes out your engine.
But don’t just slop any antifreeze into your vehicle. Check your owner’s manual or ask your Tupelo NAPA AutoCare Centers service specialist if you don’t know what is the right type of antifreeze for your vehicle. Using the wrong kind can void the warranty on your pickup cooling system.
You may have noticed that different types of antifreeze are different colors. Manufacturers tint them different colors to make them harder to mix up. It’s easy to notice that you have purple fluid when you normally use green! That way, you have less chance of damaging your pickup engine by using the wrong antifreeze.
One last word of warning — a little outside the area of car care. Never, ever let anyone or pets drink coolant/antifreeze – it is deathly poisonous.
Take care of your car, and take care of yourself! Just some good car care tips from Tupelo NAPA AutoCare Centers to keep you on the road and help your life in Tupelo run more pleasantly.
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 Tupelo 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 fins 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 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 Tupelo 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 Tupelo NAPA AutoCare Centers in Tupelo.
If your pickup 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 a diagnostic examination. This service is important 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 pickup so that it can be driven to a service center for proper car care. For this reason, 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 your Tupelo service center or Tupelo NAPA AutoCare Centers where they can inspect the cooling system, repair any leaks, and clean it if necessary. They can identify what caused the emergency situation in the first place and ensure it doesn’t happen again.
Regular maintenance of a vehicle’s cooling system is just good auto advice for Tupelo car owners. Cooling system service is relatively inexpensive and doesn’t take long at Tupelo NAPA AutoCare Centers. Lack of it, however, can put a vehicle in the scrap heap.

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 Tupelo motorists. It circulates coolant through the radiator and your engine to protect your pickup 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 pickup. 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 Tupelo NAPA AutoCare Centers. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your automobile manufacturer’s owners’ manual or knowledgeable Tupelo NAPA AutoCare Centers 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 Tupelo auto 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 Tupelo NAPA AutoCare Centers service specialist 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.
Tupelo car owners 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 knowledgeable Tupelo NAPA AutoCare Centers service professional what he thinks. Don’t feel too bad if your water pump gives out. They will all wear out eventually. Your Tupelo NAPA AutoCare Centers service advisor can get you back on the road and on with your life.
You may know that most automotive failures in Tupelo MS are tire related, but do you know the second most common cause for vehicle failure? Nope, it’s not teenagers. It is the coolant system. But, if you take good care of your coolant system, it will take good care of you.
A car’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 engine operates at the proper temperature and all is well. Without antifreeze in your cooling system, the water could freeze and cause 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 Tupelo service center knows the manufacturers’ recommendations, and can tell you when the coolant needs to be changed. They can also perform a coolant system service.

Even the best antifreeze cannot completely protect the coolant system from harmful deposits forever. The anti-corrosion additives are used up over time, so the coolant must be replaced. A coolant service cleans out the system and replaces the old fluid with fresh coolant. A coolant system service is a low-cost way to protect against major engine repairs down the road. Prevention is the key. Be sure to watch out for the two main warning signs: if your temperature gauge is in the “hot” zone or if you get a message warning you to check your coolant. If you take a look under the hood, you will see the coolant overflow bottle. You can see there are lines that indicate the proper level of coolant … if your engine is cold – or if it is hot.
You can add water or antifreeze to that bottle yourself, but be careful. First, you never want to open the radiator pressure cap. The steam could severely burn you. Second, try to get to your service center 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 your service center where they can make necessary corrections. Fourth, not all cars use the same type of antifreeze.
You will need to check your owner’s manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. If you’re not sure, ask your service technician at Tupelo NAPA AutoCare Centers for guidance.
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 knowledgeable service technicians at Tupelo NAPA AutoCare Centers. 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 Tupelo NAPA AutoCare Centers in Tupelo, just give us a call: 662.842.0036. 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 Tupelo, 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 Tupelo, 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 Tupelo service center inspect your hoses at least once a year and replace them, if needed, before they break.
Tupelo NAPA AutoCare Centers can help you check your cooling system and make any necessary adjustments or repairs. Give us a call at 662.842.0036.
The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common, it is easy to prevent.

The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then goes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it’s back to the engine again.
There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is a mixture of water and antifreeze. The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage.
Another very important coolant issue that is often overlooked is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and other parts from rust, scaling and corrosion. Old coolant may still keep your engine cool, but it won’t protect it from corrosion.
If you see a warning message to check the coolant or if the temperature gauge is in the hot zone your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious. Remember four things.
- First, you never want to open the radiator pressure cap. You could be severely burned.
- Second, try to get to your Tupelo service center at Tupelo NAPA AutoCare Centers immediately if your coolant is low. If that is not possible, follow the directions in your owners manual – it will direct you to only make additions to the coolant overflow bottle.
- Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your Tupelo NAPA AutoCare Centers service center where we can make necessary corrections.
- Fourth, not all cars use the same type of antifreeze. You need to check your owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to rely on your Tupelo NAPA AutoCare Centers service center in Tupelo to do things right.
Remember, your Tupelo service center has the equipment to change your coolant quickly and inexpensively.
