Why Your Car Overheats

Whether you know little about cars or perhaps you're going to a mechanic this is one area about cars that's worth knowing about. Why? Because in most cases the problem is usually found, fixed and the overheating is no longer a problem. But... what if nothing appears to be wrong? What then?

Well, there is a 2nd list of odd reasons and problems that could be the cause. Simply put... think of it as a a war going on under your hood. The enemies are many, but two of the main ones are heat and a vehicle's coolant system.

Your car's coolant system is designed to go to war against this heat. But when the car's coolant system fails or runs effectively and inefficiently, then heat can get the upper hand in the battle! And in due course win the battle by killing your engine.

Minor problems can lead to overheating

One of the first places you should never overlook is your radiator hose. But it's NOT the one coming out of the engine to the top of the radiator. Nope!

It's a second hose at the bottom of the radiator that runs to the engine. This particular hose delivers cool coolant to the engine. It's generally where the water pump interfaces with the system and moves the coolant. But as the hose ages, it looses some of its flexibility. This can oftentimes lead to a more serious problem because the water pump creates within itself a vacuum to move the coolant.

The hose can accurately suck in on itself such that the walls of the hose crimp. And it doesn't have to crimp much to reduce the flow of coolant. Even a tiny reduction in the flow of coolant can cause your car to overheat. Try replacing your hoses to see if it resolves the problem.

Heat that can really cripple an engine.

Another area which is often overlooked is the car motor oil. But is motor oil part of your coolant system in your car? The answer is Yes! Motor oil not only lubricates, but it also removes huge amounts of heat from the combustion chamber when it's recycled down through the oil pan.

If you overlook checking your motor oil, then there's a good chance overheating could result. Being only a half a quart low on oil can reduce the heat removal by as much as 10%! Of course, this doesn't sound like much, but it truly is in the modern car engine.

Always change your oil and make sure you maintain the right level of motor oil in the engine as recommended by your manufacturer.

Change your oil and oil filter regularly

Here's another area that most people are not aware of... and... that is the timing of your car can also be a main cause of overheating. Here we're talking about a lag in the timing. This results in the gas and air mixture exploding after the piston has reached the optimal point. If the explosion lags behind excessively, then it's possible for the engine to deverlop what's commonly referred to as: "speed wobbles." Plus... huge amounts of heat will be produced.

A inexpensive diagnostic test should be able to reveal if this is a problem. So, in conclusion, the solution to overheating is often not that expensive. But you may have to dig a bit deeper to find out what the real reason for the overheating. You can find helpful advice on options dealing with engine failure.
