Re: 85 CGT overheating

[Huw Powell <human@nh.ultranet.com>]

I had a similar problem this summer (on my 82).  Almost swapped fan,
then discover it worked.  Yeah, just connect 12v to it, the right way
round.

My sensor in the rad was good, the relay was good.  Turned out to be the
connection at the fuse box, or rather, the actual mounting for the fuse
for the fan.  Melting...

For testing purposes, you can pull the two wires off the sensor on the
bottom rear of the rad. and jump them, fan should run all the time
then.  If it does, btw, the sensor is bad.  

If you have a complex after run fan system, work around it.  I don't,
didn't have one until I rerouted the fan circuit to a B+ terminal on the
box (and installed a separate inline fuse), so now I have a "simple"
after run fan.  I guess some cars have another relay for it.
