tommac Posted March 5, 2008 Share Posted March 5, 2008 Hi all, our 94 300tdi defender - has an odd hiss/high pitch squek when its warmed up on tick over- rev it and it goes - very weird! Have changed the cam belt last couple of months- replaced alternator belt and tensioner as it had play in- still hasnt cured it. With my head under the bonnet it sounds like its coming from the water pump area- any ideas? Thanks Tom Quote Link to comment Share on other sites More sharing options...
Gromit Posted March 5, 2008 Share Posted March 5, 2008 Water pump bearings get nice and squeaky. Try squirting some WD40 into the back of the pulley and see if it stops. Quote Link to comment Share on other sites More sharing options...

And if it does change it asap to save failure at a later date Quote Link to comment Share on other sites More sharing options...
