Looking that way Lee

Depends on the fan your using, if it is rated at 30amp's then 30 amp relay (40 then 40) and the wire need's to be capable to.

I cant see anything marked on the fan Marc.Its an aircon fan from an e34 if anyone its rating.

What gauge of wire would you recommend ?

[zaust]

Your fan is the same as mine so a lower amps as I found with the tester, 16 agw is fine as long as you use 1.5 meter's of it 30 amp relay and 25 amp fuse.

Think i can safely say the problem is sorted.

Wired the fan properly through a relay wire thicker wire and let the car heat up at idle to halfway,switch the fan on and the temp dropped and sat just off the 1/4 for a good 20mins .

Well chuffed its finally sorted.
I have bought a bmw 85-90 fan switch so will just need to find the plug for it at the breakers and get it all wired neatly .

Some good came out of it i suppose.I now have a spare e28 535 rad and a m30 head gasket kit in stock now

Thanks for your help/input guys .
