3 Major Causes of Car Engine Overheating

Causes of Engine Overheating

If your check engine light illuminates, know it that trouble is around. There are plenty of reasons why vehicle’s check engine light illuminates. It can be because of loose gas cap, blown head gasket or most importantly faulty chip. But when it comes directly to engine overheating, there are three other factors responsible for it. Before the problem occurs, it gives several indications and it is on driver to notice them.

One of the very first signs of an overheated vehicle’s engine is an elevated level of temperature gauge. It often starts to exceed the internal temperature level of engine and you can witness it on dial. If this does not happen, you will witness smoke coming out of hood or there will be foul smell of fuel burning. These are all prominent indications of an overheating engine. Following article covers 3 probable causes of engine overheating.

  • Radiator Issues:

Bad radiator fan and faulty radiator are two main causes of engine overheating. The main function of radiator’s fan is to blow air over its fins to control coolant’s temperature. If this comes loose or starts spinning freely, coolant temperature will rise and engine will be overheated. A radiator can turn into a faulty component because of clogs, leaks or broken lines. Because of all this, it will not work properly and engine will overheat.

  • Cooling System Issues:

When car’s cooling system lines are blocked with sediments and rust, engine will overheat. This is because dirt and rust will inhibit the functioning of cooling system. To prevent this from happening, immediate replacements or fluid flushed is extremely important.

One other problem of cooling system which causes engine to overheat is leaks. When there are leaks in cooling system or the concentration of coolant is not appropriate, engine will overheat. To prevent this get an even coolant to water ration.

  • Thermostat Issues:

Engines often get overheated because of thermostat problems. A thermostat is basically heat sensitive valve which opens and closes according to varying engine temperature. If due to leaks or clogs thermostat gets stuck in its closing position, the temperature of engine will reach to maximum level and driver will have a serious problem to face. If thermostat gets damaged in the process, you can purchase a new one from our online auto parts superstore.
