The viscous fan will spin even when freezing cold but you should be able to stop it easily until it starts to warm up. The test for correct working is can you spin the fan when the engine is cold and is it hard to turn when engine is hot (engine not running).

having the viscous fan stuck is no problem when i bought mine, mine was welded so it was on all the time so i wudnt worry as they heat up alot on the motorway so that wont be ur problem
treeman:
well iv jus took the thermostat out tonite an il see how that goes, jus hope it aint the head gasket thats gone, i dont fancy having a warped head at the end of the day,i kno how i drive :roll: :lol:

i would check oil & water for contamination of each other.. if its been stood for a while an air lock is possibly the most likely cause, you say a top hose from the rad was leeking under pressure? - this will be how air is getting in to the system (when the engine cools, fluid settles to the low point, and contracts, creating a suction ths pulling air in) that would be my first point of call, its worth running a hose through on the system to clear out any gunk etc, as the wont help!
