What engine do you have?
This is as easy as it gets.

ADJUSTMENT



Alternator Belt


2.5L, 3.2L SHO, 3.8L AND SOME 3.0L ENGINES


The V-ribbed belts used on these engines, utilize an automatic belt tensioner which maintains proper belt tension for the life of the belt. The automatic belt tensioner has a belt wear indicator mark, as well as MIN and MAX marks. If the indicator mark is not between the MIN and MAX marks, the belt is worn or an incorrect belt is installed.


3.0L ENGINE WITHOUT AUTOMATIC TENSIONER-EXCEPT SHO




  1. Disconnect the negative battery cable.



  2. Loosen the alternator adjustment and pivot bolts.



  3. Apply tension to the belt using the adjusting screw.



  4. Using a belt tension gauge, set the belt to the proper tension. The tension should be 140-160 lbs. (533-711 N) for a new belt or 110-130 lbs. (356-445 N) for a used belt on vehicles through 1991. On 1992 vehicles, tighten to 190-210 lbs. (845-935 N) for a new belt and 140-160 lbs. (622-712 N) for a used belt.



  5. When the belt is properly tensioned, tighten the alternator adjustment bolt to 27 ft. lbs. (37 Nm).



  6. Remove the tension gauge and run the engine for 5 minutes.



  7. With the engine OFF and the belt tension gauge in place, check that the adjusting screw is in contact with the bracket before loosening the alternator adjustment bolt. Rotate the adjustment screw until the belt is tensioned to 110-130 lbs. (356-445 N) for vehicles through 1991 or 140-160 lbs. (622-712 N) for 1992 vehicles.



  8. Tighten the alternator adjustment bolt to 27 ft. lbs. (37 Nm) and the pivot bolt to 43 ft. lbs. (58 Nm).


3.0L SHO ENGINE




  1. Disconnect the negative battery cable.



  2. Loosen the idler/tensioner pulley nut.



  3. Turn the adjusting bolt until the belt is adjusted properly.


Turning the wrench to the right tightens the belt adjustment; turning the wrench to the left loosens the belt tension.




  1. Tighten the idler/tensioner pulley nut to 25-37 ft. lbs. (34-50 Nm) and check the belt tension.



REMOVAL & INSTALLATION


When installing belts on the pulley, ensure that all of the V-grooves are making contact with the pulleys.



2.5L Engine


ALTERNATOR, POWER STEERING AND AIR CONDITIONING BELT


See Figure 1




  1. Insert a 1/2 in. breaker bar into the square hole in the tensioner, then rotate the tensioner counterclockwise and remove the belt from the pulleys.


Be careful when removing or installing belts that the tool doesn't slip!
