Hey all,

Went and did a bit of a hill climb yesterday, the first workout for the engine since fitting a thermo fan (and the shiney new AVM hubs!). Temp went up, but nothing bad. Took a little while to cool back down though, even facing the rad into a stiff breeze.

Would there be any drama's in wiring up the air con fan as well as the thermo? The air con fan is a 'pusher' and only overlaps the thermo fan by 1/3rd, and there would easily be 6 inches between them.

Also, would I just run a wire from the 'trigger' off the thermatic switch (Davies Craig one, as per the proper set up) to the trigger on the air con fan relay?

Cheers,
Paul

did you have the engine running to pump the coolant when it was cooling down?

but yes you can, but put a diode on that wire so the aircon doesnt trigger the thermo fan

Thanks Royce!

Yep, the engine was going, and by a while, I only mean about 1.30 mins for the fan to stop once we stopped on top of the hill, and it was going from about 1/3 of the way up the hill (about 200m long, maybe more - it took a while in 1st low!)

I can get a suitable diode from Dick Smiths I assume? I had forgotten that electcity flows in either direction

yeah IN4004 will do the trick, band on diode on the AC relay end

also check that the AC relay is positive switched and not negative switched 1st
