The first tell-tale sign that there’s a problem with your car is when the check engine light illuminates. There are a number of reasons behind this and it may include a faulty chip, loose gas, blown head gasket or something worse. However, when it comes to your engine overheating, there are 5 possible causes behind the problem.
According to experts, there are two common radiator defects that cause the engine to overheat. First is a faulty radiator fan. It is designed to blow air over the radiator fins to help regulate the coolant’s temperature. If it loosens, spins freely when the engine is off, or has broken shrouds, it will not be able to function properly and cause the coolant temperature to rise, thus resulting in overheating. However, if the fan is not the issue, it could be the radiator. Broken lines, clogs, and leaks can cause a radiator to malfunction, which ultimately leads to overheating.
It is also important to inspect the thermostat when engine overheating becomes a problem. It is a heat-sensitive valve that opens and closes according to engine temperature. When something goes wrong and the thermostat ends up in the closed position, the temperature of the engine will rise.
Cooling System Issues
Sediment, rust or dirt can block or clog a car’s cooling system. This prevents the cooling system from functioning properly, thus triggering overheating. Hence, flushing and/or replacing fluid is necessary.
Belt and Hose Issues
Loose and broken belts, as well as, burst or worn hoses, are also a common cause of overheating engines. Belts turn the water pump, which is important for the cooling system and more. If they cease from working, so does the cooling system. A faulty hose also leads to leaks, which indicates a lack of coolant. Also, this triggers the car to overheat.
Water Pump Issues
Touted as the heart of the vehicle, the water pump works by pumping coolant just like how the heart pumps blood. However, a vehicle’s water pump pressurizes and propels coolant via the cooling system, so it plays a huge role in a car’s temperature control. In the event that something goes wrong, the coolant will not reach the engine, and it gets extremely hot.
Next time you see the check engine light illuminating, don’t ignore it. Don’t predispose yourself and your passengers to the dangers of engine overheating by taking your car to a reputable car workshop immediately.
