Why would my serpentine belt keep falling off?

Question

I have a 1998 escort ZX2. I have replaced the belt and tensioner and the belt still comes off. It may go a couple of days or a couple of weeks before it comes off again. Usually happens while I am at a stop and engine is at idle.

Answer 1

I am willing to suspect that either the pulleys are having trouble gripping the belts or your serpentine belt has too much lubrication on it. This happened to me once and after the mechanic tightened the pulley latch and the belt adjustment, everything was fine.

Answer 2

As the other person said, use a 2" - 3" steel straight edge available at Home Depot, Lowe's, large hardware stores or contractor supply stores to check the alignment of all pulleys. Spin all accessory pulleys by hand to see if there's a bad bearing in the power steering pump, water pump, *air conditioning compressor clutch (I suspect that is what it may be) and the alternator.
Something is causing an intermittent heavy drag on the belt and a bad AC compressor can do that.
