Why is the Magotan's fan not spinning?
2 Answers
Reasons for the Magotan's fan not spinning: Coolant temperature not reaching the required level: Most automotive radiator fans operate with electronic temperature control, so the fan typically only starts spinning normally when the engine coolant reaches the required temperature. If the temperature is too low, the radiator fan won't rotate. Relay malfunction: If the coolant temperature meets requirements but the radiator fan still doesn't work, it could be an issue with the fan relay. A faulty relay can prevent the radiator fan from operating. Thermostat switch problem: If neither of the above issues is present, you should check the thermostat switch, as it can significantly affect the operation of the radiator fan and should therefore be inspected as well.
I encountered this issue myself a while back, and later found out it was a blown fuse for the fan. If the car fan isn't spinning, the first thing to check is the fuse box, which is the black box in the engine bay. Open it up, look for the fuse marked with a fan icon, pull it out with pliers, and check if the metal strip in the middle is broken. If it's broken, just buy a replacement of the same spec at an auto parts store and swap it in. Also, the fan relay is prone to failure—it's that small square next to the fuse box. Pull it out and shake it to listen for any loose parts inside. Another possibility is a faulty coolant temperature sensor, which can misread the temperature and prevent the fan from working. This issue can range from minor to serious. Once, my fan stopped working, causing the temperature gauge to skyrocket, and I almost ended up with a seized engine. As soon as I noticed something was wrong, I pulled over immediately.
