Hi all,
I have a problem I can`t seem to get my head round, my rad fan is not kicking in (except once yesterday for a minute), I have replaced the fan switch on the rad but this has not fixed the problem but if I short the connector on the fan switch the fan operates.
I noticed the thermostat housing has a sensor on it does this have any control on the fan? and if it does can i bypass it to see if that is the cause?
what I have done:-
Replaced rad a few months ago as the old one sprung a leak.
Replaced switch on Rad
Bled coolant system and checked that I get a return flows to the header tank when the engine is revved slightly.
but the fan will not kick in, if I bypass the switch on the rad so the fan is on constantly i have no issues with overheating so the overheating is being caused by the fan not kicking in.
any suggestions?
