Cooling fan issues **UPDATED**

Ok so fan will not turn on at all... All the way up to 238 (hottest I let it get before I shut her down)

It never turned on.

I disconnected the plug to the fan, and connected it directly to the battery. And it ran like a champ

-the fuse is good

-I don't know how to check the relay

-and I'm not sure now to check the thermo switch for the fan.



Any ideas?

You should be able to short the leads to the thermo switch and plug the fan in. If the fan runs then you know the thermo switch is bad. Otherwise, you have a power interrupt somewhere.

Your fan may be doing what mine is doing. How is the shroud? Is it OEM and undamaged? What about the radiator

My fan and assembly is just fine, the shroud is bent and the radiator is warped such that when the shroud and fan sit on the radiator it cannot spin because it does not have an even surface to sit on.

You can rule this out if your radiator and fan assembly are undamaged or recently replaced, however.

The thermo switch works by closing the connection when it gets to a certain temperature.

You need to mimic this behavior by connecting both wires that usually go to the switch together, completing the circuit. There are many ways to do this, (piece of wire, screwdriver, etc.) you should be able to figure it out. kinda like sticking a fork in a light socket as a kid.

Be sure the fan can spin freely as stated above.
