I'm wanting to fit a new fan switch and I'm sure I saw a post at some point on the topic of fan switches and the temps they kick in. I have a S1 and am wanting to fit one with the lowest temp trigger. Does anyone know which one it is I'm after?

 

bttt

 

no one know?

 

I am sure it was a Cosworth one

 

Ask Dave esc

 

got a feeling it was a 4x4 saph but cant find the post using the search

 

I think you are right mate

 

Anyone know for sure?

 

the cossie one cuts in extremely low! i tried one on my turbo technics 4x4 and once it came on it wouldn't fooking go off again! if your local car spares has a quintin hazel book they have all the on/off temperatures for all the fan switches.
i think i settled on something like a 1600 escort diesel.there is a also a vw thermostat that can be made to fit from a golf diesel.it opens at 80 degrees instead of the usual 85-90 of most ford ones.hope that helps.

 

The cossie one comes in something like 15 degrees lower, theyre not expensive from fords either
