This suprised me and I have checked and double checked and am unsure what I have done wrong.

I recently bought a 2wd Saphy Cosworth, as my first upgrade I have installed the 4wd intercooler onto it.

Since doing this my engine struggles to get upto its normal running temperature.

I have double checked the coolent system and the car has a new thermostat installed last week which was working perfectly. Can you guys think of anything I may have missed?
