* Low coolant/ coolant leak: Overheating is often the result of a lack of coolant, which can be due to a low coolant level or a leak in the coolant system, including the radiator, hoses, water pump, or head gasket.
* Water pump failure: The water pump is responsible for circulating coolant through the engine. When the water pump fails, it cannot properly cool the engine.
* Faulty thermostat: The thermostat regulates the flow of coolant to the radiator. If it sticks closed, it prevents coolant from flowing through the radiator and cooling down. A thermostat that is stuck open may let coolant flow through the radiator too quickly and not allow it to cool properly.
* Clogged radiator: The radiator is responsible for dissipating heat from the coolant. If the radiator becomes blocked or clogged with dirt, debris, or insects, it can restrict airflow and reduce its cooling capacity.
* Faulty radiator fan: The radiator fan is responsible for drawing air through the radiator to cool the coolant. If the fan is not working properly, it won’t be able to draw enough air through the radiator and the coolant will overheat.
* Old or worn-out components: Radiator hoses, belts, and other components can deteriorate over time and become less effective at their jobs, leading to overheating.
* Head gasket failure: A blown head gasket can allow exhaust gasses to leak into the cooling system, pressurizing it and causing the engine to overheat. A blown head gasket is a serious issue that can cause significant engine damage.
