So, okay,

I've had nothing but trouble with the electric fan for the radiator 
since I bought my Coupe in 82.

Slowly but surely I have outboarded the 25 amp fuse that the fan runs 
through to keep the fuse from toasting its contacts and becoming 

Then I changed out the switch in the bottom of the radiator and things 
worked well for a couple of years.

But now I have the *way cool* problem that on very hot days the fan 
will not come on but on cool days it comes on and off fine. When it 
begins to overheat and I pull in to run water through the radiator 
vanes to cool the engine down the fan will often come on once the car 
is back to a more normal temp.

So, all I can think is that the switch in the bottom of the radiator is 
intermittent in some way.

But thought I would ask before I go and swop it out as I have to drain 

I noted that there are a couple of different switches available on the 
online parts sources and any advice about those is welcomed.

Thanks for any hints/tips/advice.
