i hope this is a simple one, is it normal on a tractor that when the viscose fan fully locks when in traffic it sounds like a force 9 gale when you start moving again, ive had these fans on senators etc & have never heard anything like it before, it does go when ive driven a while as everything cools down a bit but this noise is horendous

You must have one of the only ones that works correctly....and the Senator ones should do that to when working right!

Yes I think. My first two td's sounded like intercity 125's. My current vicous doesn't work I left it on , it spins around harmlessly!!!!

mates 530d touriing has same, he noticed funny noise, changed the still working viscous, cured it.

My viscous doesn't make a noise. Its sat in the garage, where it belongs.  Along with teh 2 spares.

OT that was a bit harsh, but im trying a new idea now, i sit in it & drive it as nice as the underneath looks anyway OT  i think your saucer of milk is ready now

lol couldnt resist it and as the car is now performing well you can look back and laugh!!!!

[unlucky alf]

have you done away with it TB? Ive been told the electric fans are good enough, what say you?

[unlucky alf]

OT who said it was performing well, sometimes the gears sound like they are slipping a bit or is this the chip confusing the box??

Haven't had mine on for 15 months.  Admittedly I have a very good cooling system on mine (new pump/stat/rad/pipes/hbv), never seen it about 97C since then.  And its been hoofed up and down lake district passes, and hoofed along my private test track at full throttle for 3 or 4 miles to see what speed it would hit...

i cant go 25ft without speedbumps slowing me down, sometime i would like a 2nd opinion on my g/box just to put my mind at rest, it could just be a phobia after what ive been through :-/ but as OT says ive had a laugh about it since.

[Omegatoy]

chip will be working the gbox hard but if its in good condition should take it ok,

My viscous fan clutch is brand new and it is always engaged.
The noise is just plain awful.
We've tried replacing it three times, presuming it was faulty, but it just keeps roaring, from cold and when the engine is hot. [smiley=angry.gif]
I do not contemplate removing the affair however, because summers here (France) can get very hot indeed, and the two aircon fans don't seem purposeful enough to keep up with the task.
