Thanks jack

f*cked tensioner or idler pulley I'd guess, best get that changed pretty sharpish...

[Piggy]

have you taken anything else off yet...be a bad pulley or water pump I expect.

fyi: you are SO lucky that hasnt gone bang

[underground375]

^^^ what they said. That belts ready to go bang any moment looking at the big split on it.

[306Puggy]

Surely there must have been quite a noticeable noise?

[Check30]

Yes there was that's how i cane across it that was a new belt.
changed the water pump and the tensioner.
Il get it changed tomorrow and check every thing over

[londondan86]

Is the new tensioner fastened up correctly? When you put a new belt on obviously check for play in the tensioner and idler but check that the new belt tracks ok for a few mins with the cover off

Mine did this when the bearings went on the water pump.
