Hi what temperature should my fans cut in on my fiesta.i have a kenlow adjustable fan switch and at the moment they cut in at 80° and hold the temp at that and dont turn off untill driving.are they set too low and what temp should they be comming on at?
The engine is a zetec turbo if that makes any diffrence

 

I set mine in the high 90s think it was 98 then runs untill 92

 

I was thinking about doing mine so it comes on at high 90's aswell because thinking about it now my thermostat isnt open untill high 80's
