I just installed a new radiator in my 1992 Legacy Wagon (non turbo)

and I noticed one of the fans isn't working. Are they both supposed to come on when you start the car?

The car is running hot , the temp gauge goes all the way up to H

How do I fix the fan?

Thanks for any help

I suspect the fan you are talking about is for the AC unit. It should come on when the AC is turned on. If the engine gets really hot, the second fan turns on also I believe.

 

Since the engine is getting hot I would try replacing the thermostat if you haven't done that yet. It is best to use an OEM unit and be sure to install it like the old one is installed. If the a new thermostat doesn't fix things then there may be a headgasket leak causing the overheating. Check for bubbles in the coolant reservoir while the engine is running and after it is shut down.

From what I know about legacies, both fans should come on at the same time.

 

You'll notice the fans have 3 wires, that is for 2 speeds.

 

Make sure both fans are plugged in. If the one is still not spinning, test for votage to the fan, and jumper the fan to 12v to verify it works. But both fans should come on.
