Low coolant? Cooling fan not working? Thermostat not opening? Water pump not circulating coolant?
Low coolant? Cooling fan not working? Bad thermostat? Cooling system airbound? Water pump not circulating coolant? Radiator core plugged or restricted? Bad radiator cap?
Yes, if the radiator fan is not working, it can cause overheating of the engine. The radiator fan helps to cool down the engine by pulling air through the radiator to remove heat. Without the fan, the engine may not receive adequate cooling, leading to overheating.
Low coolant? Bad thermostat? Radiator plugged or restricted? Cooling system air bound? Cooling fan not working? Water pump not circulating coolant?
Yes, it should. You may need to check your sensor on your cooling system. There are other things can make it over heat also. But if your fan is not working, that may be it.
Low coolant? Radiator plugged or restricted? Cooling fan not working? Water pump not circulating coolant? Thermostat not opening? Cooling system airbound?
Overheating can be caused by several things. Make sure that the cooling fan comes on when its supposed to. Make sure that air can flow through the radiator cooling fins. Insure that the thermostat is not stuck shut, the water pump is working, and that the coolant is flowing properly. One of these would be the most likely problem.
