Not So Hot in Kannapolis

Posted January 13, 2019 02:04 AM

When the weather turns cold, it's nice to crank up the furnace and enjoy the heat. But if your home's furnace doesn't work, it's not too comfortable. Same goes with your vehicle. When the heater's not working, things can get miserable. It could also signal some major problems, which we'll discuss later.

A vehicle's heating system is fairly complicated. It's made up of several parts, including a blower motor/fan, a heater core and some mechanical and electrical components. In basic terms, a vehicle's engine warms up coolant which is then sent to the heater core (which is kind of like a small radiator) behind the dash. That blower motor sends cold air through the heater core which heats up the air. Voila! Heat.

Diagnosing problems in this system takes a trained mechanic because of the different possible issues. Your heater core may need replacing; they are sometimes in tight spots and may be difficult to work on. Another possible problem could be a defective thermostat, which regulates how the coolant flows through the engine. You may have a leak somewhere in your cooling system. Those leaks may be something as simple as a detached hose clamp or as serious as a bad head gasket. A knowledgeable technician at Brothers Tire will be able to track the problems down.

For those reasons, it's wise to get your vehicle's heating system repaired. Not only can driving an unheated vehicle on a cold day freeze your fingers, some related engine problems that are not repaired could leave you stranded.

Smart drivers keep up the maintenance on their vehicle's cooling system; it's a hot tip to prevent a cold vehicle.

Engine Hydration for Kannapolis Drivers: Role of Your Water Pump

Posted February 20, 2018 10:08 AM

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 Brothers Tire 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 Kannapolis residents to replace both of these parts whenever either one needs it.

Replacing a water pump at Brothers Tire is a vehicle care issue that almost all of us Kannapolis 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 Brothers Tire service advisor.

Brothers Tire Radiator Service

Posted February 25, 2016 01:39 AM



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 in Kannapolis, 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 passes 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 comprised of water and antifreeze. The proper ratio keeps the coolant from either boiling away or freezing. Understandably, either can lead to massive engine damage.

Another coolant issue that is often overlooked by Kannapolis drivers 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. That old container of coolant gathering dust in your garage may still keep your engine cool, but it won't protect it from corrosion.

If you get a warning message to check the coolant or if the vehicle 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, get to Brothers Tire in Kannapolis immediately if your coolant is low. If that is not possible, follow the directions in your vehicle 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 Brothers Tire service center where we can make necessary adjustments.
  • Fourth, not all cars use the same type of antifreeze. You need to check your vehicle 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 depend on your Brothers Tire service center in Kannapolis to do things right.

Remember, Brothers Tire has the equipment to change your coolant quickly and inexpensively.

Cool Running in Kannapolis

Posted November 17, 2015 12:00 PM

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 Kannapolis waiting for your vehicle engine to cool down.

When you service your cooling system at Brothers Tire, 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 Brothers Tire is always a good source for auto advice. We've been providing quality automotive services at our convenient location in Kannapolis for years.

At Brothers Tire, we help you keep your cool which will keep you in the driving lane.

Coolant/Antifreeze Service in Kannapolis, North Carolina

Posted September 03, 2015 12:00 PM

Kannapolis auto owners may know that most automotive failures in Kannapolis, North Carolina, 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 Kannapolis service center knows the manufacturer's recommendations and can tell you when the coolant needs to be changed. At Brothers Tire in Kannapolis, we can perform a coolant system service.

Kannapolis 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 Brothers Tire in Kannapolis 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 Brothers Tire where they can make necessary corrections. Fourth, not all cars use the same type of antifreeze.

Kannapolis 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 Brothers Tire for guidance.

Coolant Service at Brothers Tire

Posted March 06, 2015 12:00 PM

Kannapolis residents' vehicles have to operate in a wide range of North Carolina 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 Kannapolis, North Carolina, vehicles.

There are several different 'families' of anti-freeze available to us here in Kannapolis. Your owner's manual will tell you what kind you should use. Of course, the automotive professionals at Brothers Tire 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 Kannapolis, North Carolina. Regular service needs to be done at Brothers Tire 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 Brothers Tire 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.

Keeping Your Engine Cool in Kannapolis, North Carolina

Posted February 12, 2015 12:00 PM



The cooling system keeps North Carolina vehicle's engines from overheating while they are driving around Kannapolis. 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 Kannapolis 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 Brothers Tire 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 Kannapolis, North Carolina. At Brothers Tire, 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 Brothers Tire in Kannapolis, 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.

Coolant/Antifreeze Service at Brothers Tire

Posted November 12, 2014 12:00 PM

Anyone who drives a car in Kannapolis 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 Kannapolis 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 North Carolina 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. Kannapolis 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 Brothers Tire service advisor for these recommendations, as they vary widely among vehicles.

Keep Your Cool in Kannapolis

Posted April 10, 2014 12:00 PM

Kannapolis 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 Kannapolis, the water in your engine could freeze while your vehicle is sitting out in the North Carolina 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 Kannapolis.

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 Kannapolis 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 Brothers Tire in Kannapolis.

The reason Kannapolis 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 Kannapolis auto owners ask our advisors at Brothers Tire 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 Brothers Tire in Kannapolis or your owner's manual for the right kind because using the wrong coolant can void the warranty for your vehicle cooling system.

Water Pump

Posted November 28, 2013 12:00 PM

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 Brothers Tire. 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 Brothers Tire 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 Kannapolis 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 Brothers Tire 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.

Brothers Tire 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 Brothers Tire 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.
