Hi all ,

i was performing a coolant change on my classic v3 sti. Part of the procedure was to allow the coolant temp to reach operating levels and allow the fans to kick in before switching engine off. My temp sensor reached mid point, idled for a further 15 mins but the fans never kicked in. I left the car for 20 mins on idle but the fans never came on.
Both top and bottom radiator hoses reached operating temps.
I am running an esl board and map on my car also.

Would you expect the fans to kick on upoon idling for 20 mins? does this sound normal?

Gauge sat at half way , then slowly rose to hear 3/4 then self levelled again. Car has always done this in my short time of ownership but never heard/seen fans kick in.

Is there any any way to test the fans?

Thanks guys I'll try connecting the plugs for diagnostics. It should not screw anything up doing it should it ?

Thanks lads - just a thought - should fans come on if I select air conditioning?

Should fans come on when air conditioning pressed?

Thabks again!
