Fig. Fig. 5 Installing too wide a belt can result in serious belt wear and/or breakage

Inspect the belts for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately. It is best to replace all drive belts at one time, as a preventive maintenance measure, during this service operation. After checking drive belt condition, test belt tension at the midpoint of each belt. No belt should deflect more than 3 / 8 in.- 1 / 2 in. Adjust any belt on which deflection is greater than 1 / 2 in.

WARNING
Do not exert too much pressure on accessories such as the alternator; it's easy to damage an aluminum housing. Use just enough force to hold the accessory in place while you tighten the bracket nuts.

  1. Recheck the tension. It may be necessary to do this a few times before you get it right.
  2.  

It's a good idea to carry spare belts in the trunk.
