Hi all

i have a D2 V8 And its started to make a noise...looked under the bonnet - can see the ‘main fan’ is wobbly. Im no LR specialist nor mechanic so apols for ‘wording / description’ but the centre of the fan is connected to something behind it and thats also wobbling!

after a little bit of research, it looks like its the crankshaft pulley???

any advise gratefully received.

im guessing ‘dont drive’?

anywhere where i can get a description / guidance??

More than likely your waterpump is on it's last leg and is about to fall on its face...

New pump!

Any more specific on the noise? Whirring, whining, rattling?

I would listen, using a stick or a stethoscope, to everything driven by the serpentine belt on the front of the engine, and carefully examine the idler pulleys thereon.

The noise is just like the fan is hittting rubber or p,astic. Not metally. A bit grinde-y

Hi, first of all make sure that the fan is well tightened to the pulley cos on V8 the fan it's not one piece like on the td5, the blades and the viscous unit are separate parts

Iffy water pump bearing or viscous coupling bearing, your know if its the pump bearing because of the very loud knocking noise. Find out by removing the coupling from the pump and the check both. Simples.
