I have a graunchy, rattly clicky sound coming from either the idler pulley / tensioner or the viscous fan body after the fan burst apart last week so my money is on that, what I cant seem to track down, is whether the viscous fan as it connects to the engine, is just a bearing and a pulley, or does it have any connection whatsoever to the water pump?
Now I know the waterpump is TB driven, so I'm sure that the viscous fan unit is just a spinny thing with no other function than to be a belt driven fan, cept for the fancy clutch bit in the head of the fan itself, so is it straightforward to pull it and fit one off a breaker? I would get stuck in but its my work vehicle I'd rather know what I was getting into before stripping the car down yet again....any info on the VC unit much appreciated! ive googled and googled to no avail, and thats unusual.
