Inspection
Apply a force of 22 lbs. (98 N), and measure the deflection at the mid point "A" between the alternator and crankshaft pulley. see scheme 3 If the belt is worn or damaged, replace it. If the belt needs adjustment, go to next step.
- Used Belt:41 -.49" (10.5 - 12.5 mm)
- New Belt:31 -.39" (8.0 - 10.0 mm)
Inspection (2.3L)
Apply a force of 22 lbs. (98 N), and measure the deflection at the mid point "A" between the alternator and crankshaft pulley. see scheme 4 If the belt is worn or damaged, replace it. If the belt needs adjustment, go to next step.
- Used Belt:28 -.35" (7.0 - 9.0 mm)
- New Belt:16 -.24" (4.0 - 6.0 mm)

Inspection & Replacement (3.0L)
- Inspect the belt for cracks and damaged. If the belt is cracks or damaged, replace it.
- Check that the pointer "A" on the auto-tensioner housing is not beyond the edge of the indicator rib "B" on the tensioner base. (Scheme 8)
- Move the auto-tensioner "A" to relieve tension from the alternator belt "B", and remove the alternator belt. see scheme 17
- Install the new belt in the reverse order of removal.
Scheme 8
- Check the position of the auto-tensioner indicator's pointer "A", start the engine and check the position of the pointer again. If the position changes, go to step 5. (Scheme 8)
- Check for abnormal noise from the tensioner pulley. If you hear abnormal noise, replace the tensioner pulley.
- Stop the engine. Remove the alternator belt. see scheme 17
- Check if the auto-tensioner "A" moves smoothly and check for abnormal noise when the pulley is turned counterclockwise. If the auto-tensioner does not move smoothly or if the there is abnormal noise, replace the auto-tensioner. Do not move the auto-tensioner beyond its limit. see scheme 17
- Stop the engine, then remove the auto-tensioner. (Scheme 9)
- Clamp the auto-tensioner "A" by using two 6 mm bolts "B" and a vise "C". Do not clamp the auto-tensioner itself. (Scheme 10)
- Attach a torque wrench to the pulley bolt. Measure the torque when the tensioner is turned counterclockwise. If the torque is less than the 17 ft.lbs (23 N.m), replace the auto-tensioner. (Scheme 11)
- If necessary, remove the pulley bolt "A" (left-hand threads), and replace the tensioner pulley "B". (Scheme 12)
