the fan doesnt kick on but it makes a clicking noise. they will both turn on if the a/c is on. where is the fan switch at on this motor? its carburated.

 

The fan temp switch is located down on the bottom of the radiator, just to the passenger side of center.
You should be able to unplug the connection and put a jumper in there across the connection leads, then turn on the key and fans will run.
If that doesn't work for you repost and I'll get some more info for you.
if you decide to replace that swich, make sure you are going to have clearance between the radiator and front subframe; here's why, when those older cars get rolled into parking curbs that flimsy mount around the radiator gets bowed back.
So if the space is too tight, you can loosen up the top radiator mounting plate, and raise the radiator up a couple inches, then set it back down in the little rubber mounts after switch replacement.

 

ok thanks but with the fans on it still over heats is that the head gasket??
