The diesel will run without the fan and cowl using datatecs modification. Pm him for details. It's not to be used to mask a cooling problem

Get the mod info and the bits then bin the fan and cowl. Bit more usable power and better access.

More power Alan HELL the fan wobbles slightly i looked at new fans and they are around 100 quid but a viscous clutch on its own minus the fins is like 35 quid... I dont know much about them would a new clutch and swapping the fins fix this wobble?
Thanks

How does it wobble? Do the blades wobble a little or is it physically loose? You cannot buy a viscous hub for the diesels just the complete fan.

I think its just the blades that are wobbling you can rock it back and forwards. the water pump seems fine.
thanks for the help

It's physically loose then. Make very sure it's not the water pump.

Guess what I'm changing tomorrow then lol still not sure if the apparent "gains" are worth the hassle of an electric fan..

Any play in the shaft. There should be no movement whatsoever. The blades on many viscous fans wobble a little (out of track) not generally anything to worry about.

my fan showed up as a vibration when driveing, thought engines funny so checked and found the wobbly fan god knows what damage it was about to do if i hadnt found it.

Just depends on the amount of wobble, as i said most viscous fans might have a couple of blades slightly off track. There is a bid difference to causing a vibration and being slightly off track.

If it's a diesel, you can bin the viscous if the engine and cooling system are in good order and use the aircon fans instead. On the V8 they can be used as back up in case the viscous fails. Simple mod, costs less tha £15 to do.
