While engine is running and its not raining check the belts while standing to the side of the engine to see if the pulley is alligned properly. If it is, then it must be replaced or tightened. If not, then a mechanic has tampered with the pulley system at one time and forgot to put a spacer back in.

I suppose so, should be visible signs if worn badly. Check all the pulleys for wear and straightness-make sure they line up evenly and belt runs true. Have you tried a new belt? If the tensioner is worn, it may not be keeping the belt tight enough.

First of all your belt shouldn't be coming off at all period, it sounds like either you have the wrong size belt on your vehicle, or your Idler/ Belt Tensioner is going bad and not keeping your belt tight on the pulleys. I would first check to see if you have the right size belt for your vehicle and check to see if your Belt Tensioner is working properly and not frozen or seized.

Sounds likethewater pump pulley makes noise when

It sounds like you have a loose or worn alternator belt
(same belt drives water pump) That would explain the
screeching noise and the battery light on when wet.
Check the belts for tension and wear on the inside of
the belts(cracks or pieces missing) if you're going to
change the belt or belts yourself, thats the best time
to check the pullys and make sure they are tight and
spin true. Hope this helps.

The drive belt keeps coming off of the tensioner everytime it rains or snows. We have replaced the Tensioner and the belt and made sure the splash cover is on under the van. Please help!!!!!

Something may be out of line in the belt path, an idler pulley that has a bad bearing, or one of the pumps or the alternator is trying to seize-up. Remove the belt and check each pulley that the belt travels over for bearing looseness or rough turning. When the belt is reinstalled, check that the belt seats on each pulley properly. Test it by directing water from a hose while the engine is running--you should only have water thrown off in all directions. Good luck!

Well i think i have a loose pulley but im not sure my car is a 2000 ford escort but everytime it rains the belt comes off how can i fix it?

If you have a loose pulley it should matter if it's raining or not. Plus if there is a pulley out of alignment you should be able to hear it.

You need to check your belt tension and the automatic belt tensioner.
You should not be able to flex your belt more then 1/4" either way.
Your belt automatic belt tensioner should be one of the two pic's I included. For a 2000 Ford Escort Make sure there is no play in it. It should be applying a lot of tension on the belt.
Also to be on the safe side if you haven't replaced the belt you should because more then likely that is what the problem is.


The alternative is you shouldn't drive when it rains.
For the price of postage ($3.99) I'll send you a "Get Off Work When It's Raining" card. For an additional quarter I'll include the "Get Off Work When It's Slightly Damp" card and a ShaamWoW.

Ok just kidding.

Disconnect battery, disconnect altenator wire harness. Remove bolts and pull out altenator. When reinstalling new altenator, there should be an adjustable pulley called tensioner pulley that will either have to be pulled up or pushed down in order to put belt back on.

I have the same problem in my Nisan Titanwhen it has rained lately. Either moisture has gotten into the pulley system, or the belt is loose. it could be something else though.
