Why Is My Car Overheating? (Most Common Reasons)
Leaks in the cooling system
The top reason that a car overheats is due to leaks. The leak can occur anywhere in the cooling system, whether it is in the hoses, radiator, water pump, head gasket, or thermostat housing. You can typically see an external leak by looking under the vehicle.
If you’ve used the wrong type of coolant or you didn’t dilute it correctly with distilled water, the vehicle can overheat. Additionally, over time, the coolant becomes corrosive, leading to more wear in the system.
If the thermostat gets stuck closed, the coolant won’t be able to pass through, leading to an overheated engine. A properly working thermostat allows coolant to pass through when it’s needed the most.
Clogs in the radiator, as well as leaks, can cause trouble cooling the engine. When the heat can’t be pulled away from the engine, it is going to overheat.
Loose or broken belts
When a belt is loose, or it breaks, the right coolant flow can't be maintained. This happens most often when the water pump belt breaks, turning into an overheating engine.
Bad water pump
The water pump is responsible for circulating water through the cooling system. The pump can suffer from leaks and erosion after many years of use, causing the engine to overheat.
