sierra zetec silvertop converted
 

hi guys new to this forum seeking some advice and help!

i got a sierra sapphire with a 2.0 silvertop zetec conversion all been converted by someone else and everything else runs fine on it, carbs, megajolt, ecu and everything. its had a twin fan conversion done but fans dont kick in at all no matter how hot it gets, temp gauge works and fans work so im just wondering if anyone else had this issue? could it be a relay or coolant temp sensor? any advice cheers guys

So are the fans setup to run on a switched output from the Mjl or a thermostatic switch ?

If they are both on a thermostatic switch with no relay you will need a new switch and add a relay.

If they have a relay, bypass it and see if they run.
