What Causes My Car to Overheat?

A car overheating can be stressful and sometimes dangerous. Understanding why it happens can help you prevent it.

Smoke is coming out of the engine of a car.
Your car’s engine produces a lot of heat while it runs, and the cooling system is responsible for keeping the temperature under control. When something goes wrong with the cooling system, the engine can overheat.

Common reasons for overheating include:
• Low coolant levels: Coolant absorbs heat from the engine. If there isn’t enough coolant, the engine can’t stay cool.
• Leaking radiator or hoses: Leaks in the radiator or hoses can cause coolant to escape, reducing its ability to cool the engine.
• Broken thermostat: The thermostat controls the flow of coolant. If it gets stuck, the coolant might not circulate properly.
• Faulty water pump: The water pump moves coolant through the engine. If it’s not working, the engine won’t get the cooling it needs.
• Blocked radiator: Dirt or debris can clog the radiator, making it hard for heat to escape.

If your car starts overheating, pull over as soon as it’s safe and turn off the engine. Driving an overheating car can cause serious damage to the engine.
Regular maintenance is key to preventing overheating. Have your cooling system checked by a technician during routine service to make sure everything is in good shape.

If your heater blows warm air on one side and cold air on the other, the HVAC system may not be directing air the right way. This is common on vehicles with dual-zone climate control, where the driver and passenger can choose different temperatures.
