g'day all the other day my car over heated, ive realised the thermo fan doesnt come on, and that coolant is coming out of the top radiator hose where it goes onto the thermostat housing, any help would be great thanks all.
Do the thermos come on when the Air-con is switched on?
You can unplug the thermo fan and stick a multimeter on the plug coming from the car and turn the air-con on, it should read some voltage, but not sure if this can be done wiht the VT ones. If it doesnt read voltage then try replacing the thermos, it would be the easiest option rather then fault diagnosing them unless you can see something really obvious wrong.
Replac the thermostate housing and gasket. Since your doing this and it has over heater it may be a good time to flush your system and replace thermostat and radioator hoses, replace coolant with fresh stuff (use genuine) and bleed it.
