have a 2000 dodge caravan why does the belt fall off when it gets wet
when ever it rains or even snows if the belt gets wet it comes off,can you tell me why,and can it be fixed where this doesn't happen anymore
You may have a pulley alignment or idler pully issue. In dry conditions, there may be enough friction or grip to hold the belt on, but in wet conditions, it slips off. I would recommend having the pulleys checked for alignment. There could be a loose bracket on a pump, or the idler pulley could be worn.
When a belt wears it does not wear exactly even .. the moisture is absorbed and the tension increases/decreases on one side of the belt causing the belt to wander off the pulley. I also suspect there is misalignment in the pulleys
Also ... you did not indicate if you changed the belt ... no matter what the problem is ... change the belt
A gated idler pulley in place of tentioner pulley. Read carefully, just the pulley you need the tentioner
