After replacing my cam belt the last time my accessory belt started squealing. I did what seemed reasonable at the time and re-tensioned the belt, problem solved.
A while after that (I think months rather than weeks) my engine starts to make god awful knocking noises at low revs under load like when pulling away in traffic. Then it does it all the time.
I eventually identified it by rocking the waterpump pully back and fourth, clunk clunk. New waterpump and 2 months later its starting to make the clunking under load again. WTF!! I tensioned the belt according to the haynes manual specs (I dont recall the belt defection value but it seemed reasonable at the time) I have since slackened the belt right off. I can live with the squeal on startup untill I figure this out.
What else could be causing rapid waterpump death?
I suppose it started a while after I installed my crank wheel system for MS
Could the slight imbalance from this be causing problems? Its welded to the centre section of the damper not the outer part with the belts. I didnt dynamically balance it but if supercharger pullys and **** dont cause probs then this should be ok right?
Any suggestions would be great.
