Your car will warn you before its engine overheats. Smoke may stream from the hood, a warning light may light up on your dash, or your temperature gauge may slip into the red zone. Regardless of the warning, an auto mechanic will be able to pinpoint the cause of a malfunctioning engine. Check out the guide below for five reasons your car’s engine may be overheating.

Why Your Car’s Engine is Overheating

1. Stuck Thermostat

The purpose of a car’s thermostat is to regulate the temperature range. It monitors the coolant flow by opening and closing as needed. If the thermostat gets stuck, it prevents coolant from leaving the engine, causing it to overheat.

2. Low Coolant Levels

The primary function of coolant is to remove the excess heat from the engine. If your car’s coolant level is too low, an air bubble will form, preventing it from circulating and performing its job. This results in a blown engine.

3. Hose Blockage

Hoses can often be damaged by debris or dirt from the road getting into the coolant system. If a hose has been cracked or blocked, coolant can’t move to the engine to maintain its temperature. Have your auto mechanic flush the system and refill the coolant tank to verify if a hose is the source of the problem.

4. Failing Water Pump

Your car’s water pump works to circulate the antifreeze throughout the cooling system, further helping the coolant take heat away from the engine. If the water pump impeller is stuck or damaged, the flow will be disrupted, and the engine could overheat.

5. Radiator Leak

A radiator passes coolant through thin metal fins, allowing the heat to flow to the air outside your car with ease. A leak in this component will prevent your engine from cooling properly. You’ll need to either seal the leak or take your vehicle to an auto mechanic who can replace the damaged part.
