ok lads ive just swapped out my b16a for a b18c itr motor.now the car is a ukdm vti (obd2 b16).
their seems to be no power getting to the fan but their is at the relay?
only started it for the first time today and everything worked fine , idle was good , fan cut in the lot , went off put a few things back together (exhaust,bleed the breaks etc etc)then wa goin to give her a run when it starts over heating and the fan wasnt cutting in??
any help appreciated

 

make sure u let all of the air out of ur radiator.
just take the cap off and let the air bubbles come out.
