Thanks dude interesting reading, there's a 'sierra cosworth radiator colling fan loom' on ebay its mentioned in that thread I wonder is it worth a look? Has there been any feed back on these?

Tabetha- thanks for the practical sensible advice! Is there an aftermarket stat that would suit an alloy rad and one of STu fan switches?
First thing to be done this evening is make some custom air directors and remove that shield! Fair play, thanks
