Thread: Viscous engine fan failure?

Hi,

They are known to fail, but not prone to, just age related.

To test, with engine off try spinning it with your finger. If it rotates freely with no resistance, then it will need replacing.

Cheers, Jerry

Yep, it's a bit like that. Turns fairly easy.
It's going in to my LR mech next week, I'll get him to check it.

Cheers

Craig

try turning it immediately after a drive where it should have been working, if it is still good it should be very hard to turn, if it is the same as when it's cold then its dead.

Tried it.. Look like its knackered...

Grab a handful of strong rag,get a good purchase on it and gently touch the edge of the fan with the engine idling.If the hub is stuffed the fan will stop,if its ok it will try to grab the rag.Take it for a run and repeat with a hot engine,definately shouldnt stop spinning when hot and should try harder to grab the rag.
Sounds dangerous,as long as you are careful its OK.

Well before that happens, I've had a chat to my LR mechanic. Getting it replaced this week.

Yep, neighbour across road raised bonnet of his wife's car while engine running to check for leaks... then proceeded to give the rocker cover a cursory clean... rag got caught and quick as a flash dragged his hand into the fan belt... he is now minus two fingers from the middle knuckle ...
