Radiator Fan Not Working 8 Reasons Why And How To Fix Motor Vehicle Hq Radiator fans by garnet cc by nc nd 2.0. here are 8 reasons why a radiator fan might not be working: broken radiator fan. radiator fans are equipped with electric motors and if the fan motor doesn’t turn on at all, then it’s likely that the motor is fried. Then, with a cold engine, pop the fuse box and gently pull out the fuse for the radiator fan. hold it up to a light. if the wire inside is broken, replace the fuse. if the wire is connected, your fuse is fine. [1] the fix: purchase a replacement fuse for your vehicle and insert it into the port for it.
Radiator Fan Not Working 8 Reasons Why And How To Fix Motor Vehicle Hq The most common causes of why a radiator fan is not working are a blown fuse, a bad relay, or a broken wire. it can also be caused by a faulty coolant temp sensor, low coolant level or the fan itself can be damaged. while these are some of the reasons, the list is not exhaustive. here is a more detailed list of the most common causes of a. Close everything up, start the car, and check whether the radiator fan now works (set the a c on full blast). if it does, you have fixed the problem! if the fan does not work, check the new fuse to be sure it has not blown. if it has blown, contact your mechanic for repairs. Test the fan motor. connect the motor directly to 12 volt power with jumper wires to see if the fan spins properly. if it doesn’t, the motor is likely burnt out. check the coolant temperature sensor. a signal from the coolant temperature sensor is what triggers the ecu to turn on the radiator fan, and if it’s faulty, it can prevent the fan. Causes #15. inadequate coolant mixture. the coolant mixture in your vehicle should be a 50 50 mix of water and antifreeze. if the mixture is not correct, it can cause the engine to overheat and the radiator fan to work harder than necessary. check the coolant mixture in your vehicle and adjust it if necessary.

There’s no way to replace the bearing. replace the fan motor. each fan blade for. an electric radiator fan should spin freely. if it doesn’t, chances are the bearings are worn and the fan must be replaced. faulty radiator fan relay(s) carmakers use many different relay configurations to achieve multiple radiator fan speeds. Low coolant levels or signs of contamination can indicate leaks or other issues within the cooling system. additionally, inspect hoses, belts, and connections for any signs of wear, damage, or leaks. during your inspections, pay close attention to the radiator, water pump, thermostat, and radiator cap.
