What Causes a Car To Overheat?

Engine overheating is a common problem for people who use gas cars. Apart from the obvious discomfort, overheating can cause damage to the engine and other critical components. Overheating occurs when the heat generated by the motor exceeds the normal operating temperature, or the cooling system fails.

How to Detect Overheating

If your car overheats while you are driving, you will:
• see an ‘H' warning on the temperature gauge
• feel a strange smell coming from the engine
• or see steam or smoke coming from under the hood

A Problem in The Cooling System

Engine overheating is caused by a malfunctioning cooling system. The cooling system regulates engine temperature by circulating a coolant through the engine and releases excess heat through the radiator. The most common causes of overheating include:

Insufficient Coolant

Your engine should have a 50/50 mix of coolant and water. The engine can overheat if there is too little of the mix or too much coolant or water.

Cooling System Leaks

Leaks in the coolant reservoir tank can cause overheating. You can detect leaks by identifying puddles or wet spots on the ground under your car or sensing a sweet smell.

Damaged water pump

If the coolant is dirty or there is too much scale, the water pump won't circulate the coolant properly, leading to overheating.

Radiator Issues

Radiator fans release extra heat allowing the engine to cool. Damaged, malfunctioning or broken fans can reduce the radiator's capacity to remove heat.

The heater Core Is Blocked

If the heat exchanger is clogged or blocked, the coolant won't flow, leading to overheating.

Low Oil Levels

If the engine lubricants are depleted, the parts will overheat even with the cooling system working.

Thermostat Failure

If the thermostat is damaged or malfunctions, the coolant won't flow properly, leading to overheating

Damaged Hoses and Belts

If the coolant hoses are blocked or ruptured, they will not maintain proper coolant flow to the engine and related combustion and temperature regulation systems.

You can prevent overheating by taking your car for regular maintenance by a qualified mechanic. If you need engine repair, we invite you to bring your vehicle to Inmon Automotive today!
