    Viscous Fan Clutch ?

    Non-Mercedes but it is still a viscous fan? Would I be correct in assuming that my Viscous Fan is is goosed (or out of silicone oil) if it operates normally from cold but after the engine gets up to hot standing traffic temps, it locks = correct but then stays locked even after the engine and...

    Viscous coupling

    Just fitting a new coupling...when tightened onto the pulley the whole coupling sits in or almost touching the pulley behind and can turn roughly...is this correct? When fixing the fan blades onto the coupling they seem to touch the other pulleys so too far back and I am wondering if I am...

    Water Pump or Viscous Fan? 240 V6 W202

    The wifes 1997 C240 has started a metallic grumbling whirring noise at the front I thought hmmm sounds like the water pump and its quite noisy, the v6 engine normally purrs quite silently. I put the engine stethascope on it and the noise is definitely from the front end but sounds the same...

    w124 230 CE Viscous Fan not working

    Hello I've only had my w124 a couple of weeks but I noticed that it does seem to run a bit hot, although the temp gauge stays normal. However I noticed today that when I started it with the bonnet up the fan was bearly turning and could stopped completely with the lightest touch so I'm guessing...

    Viscous Coupling

    I understand that a "Viscous Coupling" works on the principal that when the oil inside gets thicker it spins quicker but surely that's not the case as fluids get thinner when hotter. Forgive my ignorance if in missing something. T.:doh::dk:

    E430 m113940 viscous coupling

    Changing the viscous coupling on the E430 looked a pretty-simple job. (Bad mistake #1) I guess the photos speak for themselves. Someone has been there before me and has butchered the 36mm hex nut that secures the coupling to the water pump pulley. I have given it everything I've got with the...

    Viscous Fan on C240 V6 doesn't seem to be working?

    Evening all, The viscous fan on my C240 doesn't seem to be hugely effective lately - if the engine is hot, then doing the old test of attempting to stop the fan blades with a rolled up news paper seems to actually stop the fan! My question is this - can you replace the clutch mechanism...

    I've just ordered a new viscous fan coupling for my W124 and need some help on how to fit it. For ref, GSF stock Sachs or Febi Bilstein at 35 +vat and ecp stock OTSA at 52 + vat.
