Drive belts — removal and installation (Honda Accord 3)

When purchasing belts, remember that the critical parameters that determine whether a belt is suitable or not are its length ("diameter"), width, depth, and angle or V-shaped profile. The shape of the belt must exactly match the shape of the pulley; belts that do not fit correctly can cause noise, slippage and premature failure.

If the belt needs to be replaced, first loosen the adjuster, if applicable. The drive part may also need to be loosened or moved toward the engine to allow the belt to be removed. Once the old belt is removed, inspect the pulleys for dirt or anything that would prevent them from making contact with the belt. Carefully install the new belt, remembering that it is unused and may be slightly smaller when it fits over the pulley flanges. Slide the belt over the largest pulley first (usually the crankshaft pulley in the center of the engine base), then slide it over the smaller pulley.

A slight tug in the direction of rotation may help seat the belt. Depending on the belt you are replacing, you may need to loosen or remove other interfering belts to get to the one you want. Once the new belt is installed, pull the drive assembly away from the engine and tighten the mounting bolts. This job may sometimes require three to four hands; get someone to help you. Make sure that all previously loosened bolts are retightened.
