The cars today do not have belt adjustments they have what is caller a idler pulls that keeps a serpintine belt "all in one belt" that snakes around all the pulleys,thus the serpintine..name..anyway if it is slipping most likely the belt needs replacing or the idler itself is bad..neither can be adjusted..the fix is replacement...your car should have a belt route under the hood showing where it goes and the idler is spring loaded and easy easy to take the pressure off to take the old belt off and replace it..not a big job for garages if you wish not to DIY .good lucK
Sounds like the belt tightener unit is wore out and needs replacing.
As the bearings wear out the pulley will move around causing the belt to come off. When you replace the tightener you should replace the belt as well.
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.
no, you set the tension by slackening the bolts on the alternator and using a long handle screwdriver wedged between engine and alternator tighten so that the longest part of the belt between pulleys has about 1/2 to 3/4 inch slack too tight and the belt will snap very soon....too slack and the belt will slip...
If the belt keeps slipping off the you need to replace the tensioner(its the pulley you have to move to get the belt on and off,and that part should be inexpensive to replace from any parts store.
If the belt was slipping or became contaminated with oil or coolant that should resolve the problem. Check the belt tension first before replacing the belt
