Open the hood and locate the belt tensioner. The serpentine belt drive is located on the front of the engine on the passenger side of the engine compartment. The spring-loaded belt tensioner on the 1998 Contour is located slightly to the left of and below the water pump pulley Release the tension on the belt using the serpentine belt removal tool. On vehicles equipped with the 2.5 liter V-6 engine, snap the 3/8 inch-drive adapter onto the removal tool. Slip the tool into the square, 3/8-inch hole in the end of the tensioner arm. Rotate the tensioner clockwise to release the tension. While holding the tensioner back, remove the belt from one of the pulleys. Release the tensioner, remove the belt from the remaining pulleys and pull it out of the engine compartment Snap a13 mm socket adapter into the belt removal tool for the 2.0 liter, four cylinder Contour. Place the tool onto the 13 mm bolt that holds the tensioner pulley to the tensioner arm and rotate the tensioner clockwise. While hold the tensioner back, slip the belt off one of the pulleys. Release the tensioner, slip the belt from the remaining pulleys then remove it from the engine compartment Route the new belt around the pulleys, according to the belt routing guide. The belt routing guide on the 1998 Contour is located on a decal on the left (passenger side) strut tower. If this decal is missing, or unreadable, the belt routing guide can also be found in your service manual. Rotate the tensioner pulley one more turn to allow the new belt to slip under the tensioner pulley. Check the belt for proper alignment on the pulleys. It should lay flat on the pulley and not overhang the edges. If the belt must be repositioned, release the tensioner and reposition as needed.
Typically a belt will come off if all the pulleys are not perfectly aligned.
If you recently replaced a power steering pump and the pulley was not properly seated all the way down where the pulley front is flush with the metal shaft from the pump then you will shred the belts and they will come off. If you ONLY swapped the tensioner and idler pulley you may have installed the tensioner so it isn't parallel to the other pulleys but that would be very rare because it would have been difficult to get the belt on if it was not properly installed. There also could be a damaged plastic pulley that could be "cutting" into the belt which would also cause the belt to slip off.
Ok. To start with check to make sure all the pulleys, idlers and equip is all there If this car is 1998 Ford Escort with 2.0 L. not ZX2 you should have 6 pulleys. You will need some metric wrenches to move the tensioner pulley. Starting at the bottom this should be the Crank shaft the belt runs on the outside of the pulley . Next to the right should be an A/C and the belt runs on the outside of this pulley next is the idler the belt runs on the inside of this one. top most pulley should be the Power steering the belt runs on the outside of this pulley and goes over to the alternator outside of this one also last is the Tensioner assembly the belt runs on the inside of this one. Now is when you need the metric wrench some are 15mm some are 16mm. You have to move the tensioner pulling to the outside to release the tension and slip the belt on. It may be easier to slip the belt off the power steering and behind the tensioner pulley then release the tensioner and have some one else slip the belt on. I Found a picture up it not the right way up the CS is the crankshaft and it's on the bottom picture should be turn 90 degrees to the left.
