Good evening, in order to help you further I need to know what size engine it has......4 cylinder or 6 cylinder and make sure there is no confusion, this is a Cherokee and not a Grand Cherokee correct? Thanks

Here is the information you requested:


Belt tension is adjusted at the power steering pump bracket and idler pulley assembly.

  1. Disconnect negative battery cable from battery.
  2. Loosen idler pulley bolt at the power steering bracket

  1. Loosen adjusting bolt until belt can be removed from pulleys.
  2. Remove belt.


  1. Check condition of all pulleys

    CAUTION: When installing the serpentine accessory drive belt, the belt MUST be routed correctly. If not, the engine may overheat due to the water pump rotating in the wrong direction.

  2. Install new belt.
  3. Using serpentine belt tension gauge, tighten adjusting bolt until belt reaches proper tension. Refer to Belt Tension at the rear of this section for proper belt tension.
  4. After belt is tensioned correctly, tighten idler pulley bolt to 47 N·m (35 ft. lbs.)
  5. After idler pulley has been tightened into position, recheck belt tension. Adjust if necessary.
