I just finished replacing my serpentine belt on a 1998 ford escort zx2 and in less than a day the belt slipped right off. I had a very hard time getting the tension pulley loose enough to slip over the last pulley, so I thought that the tension pulley was good. Not sure why it came off again (2nd time within a week). Any ideas?
Use a longer wrench or breaker bar to get more control when manipulating the auto tensioner. Place your belt against the tensioner before putting your wrench on the tensioner. then when you have it held open slip belt around the proper pulleys on either end. Make sure you have the auto tensioner held as far open as possible or as is needed.then be sure to release it nice and easy so as not to allow it to "snap back" to it's tensioned position. Hope this helps.
Hi Paul.
see if this link helps to find out why.

I have had the same trouble with my 2002 zx2. I have had to reinstall or replace the serpentine belt 4 or 5 times in less than a year. I have replaced the idler bearing and then the water pump went out which took out the belt as well. The belt still came off after replacing those items when I hit another puddle of water. I found that proper installation of the plastic engine splash guards which bolt to the bottom around the motor play an important roll in keeping out road water. Since the pulleys are accessible with the right front tire removed, I focused on securing the plastics tightly around the wheelwell framework. This has helped extremely in keeping water away from the pulleys. I haven't had any more troubles in the last 7 or 8 months. I'm still leary when driving in the rain as the routing of the serpentine belt on this car is the worst I've ever encountered.
Bottom line, check/replace idler bearing, tensioner if needed and make sure all plastic splash guards are there and properly screwed to the frame and each other.
Hope this helps.

Please tighten the grip for the belt to enable tighter stay in-line.
Sorry.

Remove the belt and check all pulleys for side play and wobble...likely you will find one loose (bad bearing) whichever it turns out to be, change it. (likely what killed the belt to begin with.) Also sight down the belt from the side and check that all pulleys are aligned with each other. any variation needs correction. Begin by checking the one you mentioned first.

There should be a belt tensioner which requires a socket and a ratchet to pull tension off the belt by prying on this tensioner in the opposite direction.. Good Luck
