Keep Your Cooling System in Check

Engine Cooling System Service and Repair Katy, TX 

When a vehicle's engine cooling system suffers long-term neglect, it turns into an on-going source of problems. Once corrosion takes place, the damage is difficult to reverse. Cooling system neglect is often the cause mechanical failure of a vehicle. In addition to the danger and inconvenience of a breakdown, the damage to the engine and transmission can add up to thousands of dollars. Discovering a leaking
radiator, hose connection, a sticking thermostat or other cooling system component that's on "borrowed time" can save the life of one's engine. Additionally, overheating can damage valve guides, scuff pistons, crask cylinder heads, and crush head gaskets.

Technical Information on How Engine Cooling Works

The engine cooling system works by absorbing, transporting, and dissipating heat. Therefore, anything that impedes any of those functions can cause overheating. Heat flows from higher temperature to lower temperature. A car's engine is generally cooled by keeping it in constant contact with a cooler fluid. As soon as that circulation is impeded, temperatures rise. The radiator must also be working efficiently to transfer engine heat to the atmosphere, and the thermostat must be in perfect working order. The engine cooling system transports heat from the engine, into the coolant, and out into the atmosphere. If the amount of heat that it picks up from the engine is roughly equal to the amount of heat that it dispenses to the atmosphere, the engine temperature will stay constant. As long as the coolant is taking on roughly the same amount of heat that it can dissipate, it will be effective. It's easy to assume that cooler temperatures are better. However, they really just give you more of a buffer before the boiling point is reached. However, a properly functioning cooling system can really operate just fine at any temperature under its boiling point. If a cooling system is taking on more heat than it can dissipate, it will eventually overheat, regardless of the temperature at which the thermostat opens. This is why using a lower-temperature thermostat often doesn't solve overheating problems. The heat that the coolant takes on must be roughly equal to the heat that it dissipates.

Katy, TX I Car Cooling System Service and Repair

A car overheating can become a big problem, it can be an engine killer that will leave you on the side of the road and an expensive repair bill. If your car has been running hot, you know the feeling. You're sitting in traffic, the light turns green, and you pray that traffic breaks enough for you to get some air flowing over the radiator so that engine temperature needle will go down just a little bit. It's beyond stressful, and there's no reason you should be forced to endure this. The fact is, there are only a few things that commonly cause an engine to overheat regularly.

5 common reasons of engine overheating

1- Low Coolant
By a large margin, the most common cause for engine overheating is simply a low coolant level. Your engine's cooling system relies on coolant to circulate and remove heat from the engine. If you don't have enough coolant in there to do the job, heat will build up and your engine will overheat.

2- Electric Cooling Fan Failure
If you have an electric cooling fan that isn't coming on, this can cause your engine to overheat. The electric cooling fan draws cooler air through your radiator when your car isn't going fast enough to ram it through from the front. You can test this by letting your car idle long enough for the engine to heat up. If you've been having an overheating problem in traffic, keep an eye on your temperature gauge. When it starts creeping into the danger zone, look under the hood to see if your electric fan is running. If it's not, you'll need to figure out why. There are two usual causes to this:

2a. Bad Electric Fan: Sometimes your fan motor will just burn out and your fan won't come on at all. To test this, find your radiator fan switch and disconnect the wiring harness. Get a jumper wire and insert it into both contacts, your fan should come on. Another way to test the fan is to turn on the air conditioning. Most, but not all, cars activate the cooling fan at either a medium or high speed when you turn on the AC.

2b. Bad Radiator Fan Switch: There is a switch that tells your cooling fan to come on when your coolant reaches a certain temperature. The easiest way to test this switch is to disconnect the wiring harness and then run a jumper wire across the harness contacts. If the fan comes on, you need to replace the switch.

3- Thermostat Not Opening
The most common symptom of a failed thermostat is overheating at highway speeds. Your engine may be able to stay cool at low speeds because it's not working that hard, and therefore not creating as much heat. But at highway speeds your engine needs lots of coolant flowing through. If the thermostat doesn't open, there isn't enough flow to keep things cool, and you'll find yourself looking more like a steam ship than a sedan going down the highway.

4- Broken Fan Belt
There are still lots of engines out there which have a fan belt to drive the engine cooling fan. If you see a belt attached to your fan, you're in this club. The good news is your repair is always cheaper than the electric guys. You can replace your fan belt easily if it's broken.

5- Clogged Radiator
If your car has more than 50,000 miles on it, your radiator could start getting gummed up. You can avoid this and other problems associated with old coolant by flushing your radiator every year. There's nothing good about an overheating problem. If your engine is running hot you should get it fixed as quickly as possible. A hot engine can do damage to itself, even if you aren't going into a full overheating. Check your oil regularly to be sure you are providing adequate lubrication to your engine, everything you can do to reduce heat buildup helps!
