Hi..there thanks for your reply..


You say its kicked off in what way? slips/works itself off or suddenly jumps off the pulleys?


Does the belt have any wear/score marks or show any signs of which along the edges etc..?


Before this problem occurred has there been any previous work done on that side?

Customer: replied 4 years ago.

just shreds the belt.

no work done to this side

this has happened a few time and usually damages seal on ps pump aswell

Hi..there thanks for your reply..


Ok..if the belt shreds as you say then I suspect one of the pulleys that belt runs round is indeed out of alignment and causing the belt to run off,there cant be anything else that would cause unless the belts coming into contact with something,unless the alternator clutch pulley is at fault or the belt isn't tight enough - it might be worth too also following the route round and maybe see if you can see any wear marks the belts left behind and maybe give any indication as to where exactly the belt rubbing you have replaced the tensioner/ps pump then you could maybe rule those out..thats only leaves really that small guide pulley/air con if fitted/alternator/or the lower crank would need to check each one in turn for any movement or free play by hand.or any signs or noticeable issues as per running out of line.maybe use a long straight edge maybe..or with the belt on observe with the engine running all the pulleys and watch to see if any are slightly wobbling especially so the lower crank pulley as I say I certainly sounds like an alignment issue..I do hope this helps further
