1994 Jeep Laredo: Fan Belt Removal

The 1994 Grand Cherokee Laredo has two engine options: the six-cylinder 4.0-liter and an optional 5.2 liter V-8 for the four-wheel-drive models. The eight-cylinder engine has an automatic belt tensioner with no need for manual adjustment. The six-cylinder engine has a manual adjustment for applying tension to the belt. The belt routing for each engine is illustrated on a sticker located on the top of the fan shroud.

Instructions

5.2-Liter Engine

    1

    If the belt routing illustration is missing, draw a diagram of the routing before removing it.

    2

    Place the ratchet with a socket on the automatic tensioner pulley bolt. Rotate the tensioner clockwise to relieve the tension on the belt. Remove the belt from the engine.

    3

    Install the belt as outlined by the schematic on the radiator fan shroud, or on the diagram you drew. Maintain some tension on the belt throughout its installation so it remains in place. Rotate the tensioner clockwise and push the belt over the tensioner. Release the tensioner.

    4

    Look at the indexing arrow on the tensioner if you are installing a used belt. The two marks on the body of the tensioner represent the limits of the tensioners travel or ability to apply tension. The arrow must be no closer than 3 mm to either mark. If it is, it means the belt is the incorrect size and the tensioner cannot apply the correct tension. If the pointer is too close to the index marks, exchange the belt for the correct size belt if the belt is new, or replace the belt with a new one if it is an old belt.

4.0-Liter Engine

    5

    If the belt routing illustration is not present on the top of the fan shroud, draw a diagram of the routing before removing the belt.

    6

    Loosen the top pivot bolt in the back of the power-steering pump using a 13 mm socket. Loosen the lock nut directly below, which also is 13 mm. This lock nut allows the power-steering pump to swivel and locks it in place when the tension is correct.

    7

    Look at the bottom side of the power-steering pump. There is an adjusting bolt with the head of the bolt facing the drivers fender. Turning this bolt swivels the power-steering pump up or down to adjust tension. Turn the bolt counterclockwise with the 13 mm socket to lower the power-steering pump and relieve the tension on the belt. Remove the belt.

    8

    Install the new or used belt around all of the pulleys, using the belt diagram on the fan shroud or your drawn diagram as a guide. Turn the adjuster bolt clockwise to apply tension to the belt. Check the belt tension as the tensioner bolt is rotated. If a tension gauge is being used to check the tension, the belt should have 180 to 200 pounds of tension for a new belt or 140 to 160 pounds for a used belt. If the tool is not available, tighten the belt until it is difficult to twist the belt more than 45 degrees.

    9

    Torque the lower lock nut on the slotted part of the mounting bracket and the top pivot bolt to 20 foot-pounds of torque.
