Can anyone help?
Once car has warmed up and the tempreture gauge reaches 90 when fan kits in, the coolant warning light goes on.
If anyone knows the reason for this please help
thanks paul

Fan control unit is fried. It's the aluminium box behind the front bumper on the passenger side, between the bumper and inner arch.
