What Causes the Engine to Overheat and the Fan to Keep Running?

[ColinRose]

Engine overheating and the fan continuously running can be caused by the following reasons: Damaged Electronic Components: There are multiple reasons that can lead to engine overheating or even "boiling over." Common causes include damaged electronic components in the cooling system (such as the thermostat or cooling fan), poor radiator performance, or insufficient coolant. Engine Overheating: Engines with electronic water pumps may fare slightly better, but excessively high temperatures without proper cooling can still strain the engine. Allowing the engine to idle for a while can help, as the circulating coolant can mitigate the impact of high temperatures on the engine. Low Coolant Level: Check if the engine overheating is due to low coolant levels or poor coolant circulation. Additionally, inspect components such as the temperature sensor, water pump, thermostat, and cooling fan, as any of these could contribute to high engine temperatures.
