300tdi Serpentine Belt
Range Rover Blues:
I replaced the tsnsioner on my sister's 300 "just as a precaution" when I did the head. The arm is slightly oout of line which throws the belt onto the front of the water pump pulley where it rides up, cuts the front of the belt off and eats the top hose. 2 belts later, one near miss with overheating and several instances of failing PAS due to belt slippage I worked out what was going wrong :evil:
So be careful, it was a branded part!
P.S. what's the penny trick?

Trap a penny peice behind the tensioner just to bring it out and ine it up better.

i found that its the pas pump that makes the belt run out of alignment and shred the edge of it.
when the pump fails it can move out of alignment i found

So are they all as poo?
David I checked all the pulley carefully now, but what really gives it away is the engine wa fine untill I swapped the tensioner "to be on the safe side" :roll:
Also it only jumps out of the water pump pulley which strongly suggests it;s the tensioner feeding it thats at fault.
