Hi guys, my first post here. I've tried searching other threads with no success.

So I have a 93 Civic, and It's overheating. I've realized it's the radiator fan that is not spinning. I tested the fan and it turns on when connected to a battery, I changed the cooling fan switch, and the relay. Nothing. I even tried the paper clip thing on the cooling fan switch and the fan turns right on. I tested the thermostat in boiling water and it opens and closes fine.

A guy at O'Reillys told me to bleed the coolant for up to an hour and that may work. But so far nothing.

If you have any idea lmk, I'm tempted to just replace the fan altogether and just try a new thermostat but I'd like to see if there may be any other other issues, especially if they' both seem to work just fine right now when tested.

Thanks in advance!

Jump the switch and test drive with the fan running all the time. If it still overheats there is a different problem.

Before the first drive, with the engine cold, open the radiator and confirm it's completely full. If not, top it up and you may need to bleed again.

Check that the heater makes hot air.
