#17: Re: Coolant overheated after car wash Author: anton1989, Location: west midlandsPosted: Sat Oct 06, 2012 3:23 pm ---- this is what happend to mine, very common
got a second hand one and new relays
#18: Re: Coolant overheated after car wash Author: karimali831, Location: EnglandPosted: Sun Oct 07, 2012 10:33 am ---- hopefully the problem is as small as this, you know how I can check it is not the water pump?
#19: Re: Coolant overheated after car wash Author: Seabook, Posted: Sun Oct 07, 2012 10:51 am ---- check the bottom and upper coolant pipe.
if both are warm then water pump is fine
#20: Re: Coolant overheated after car wash Author: karimali831, Location: EnglandPosted: Mon Oct 08, 2012 11:50 am ---- I replaced the wiring harness and relays but the fan only comes on at 105c ?? It is always go up to 105 until fan triggers and drops to 98c. Any thoughts? Thanks all for the help!

I am sure I wired it all correctly, got two new relays also.
I can only think the resistor needs changing, it looks fine, but if the high speed fan works so the resistor must work?
#23: Re: Coolant overheated after car wash Author: Edward, Location: In the garagePosted: Mon Oct 08, 2012 1:09 pm ---- High speed fan doesnt use the resistor. The low speed fan uses the resistor to restrict the current to the fan.
If you remove the resistor and bridge the wiring and the fan spins at high speed you'll know the resistor is faulty.

thanks!
so apart from the resistor, with all wiring and relays and fan working at high speed can it be anything else?
