ADJUSTMENT
Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

ADJUSTMENT
Inspect the drive belt(s) every 30,000 miles or 24 months. Determine the belt tension at a point halfway between the pulleys by pressing on the belt with moderate thumb pressure. If the deflection is found to be too much or too little, perform the tension adjustments.
On some Acura models it will be necessary to work from beneath the vehicle when servicing the accessory drive belts.
Before adjusting, inspect the belt to see that it is not cracked or worn. Be sure that its surfaces are free of grease and oil. If contamination is present, belt replacement is recommended.

REMOVAL & INSTALLATION
Many Acura models are equipped with a theft deterrent audio system. Make sure you have the necessary code before disconnecting the battery.

Alternator
To adjust the tension of the alternator
drive belt on all models, loosen the pivot and mounting bolts on the
alternator. Using a wooden hammer handle, a broomstick or your hand,
move the alternator one way or the other until the proper tension is
achieved.
WARNING
Do not use a screwdriver or any other metal device (such as a prybar) as a lever.
Tighten the mounting bolts securely. If a new belt has been
installed, recheck the tension after about 200 miles (480 km) of
driving.
Air Conditioning Compressor
A/C compressor belt
tension can be adjusted by turning the tension adjusting bolt which is
located on the compressor tensioner bracket. Turn the bolt clockwise to
tighten the belt and counterclockwise to loosen it.
Air Pump
See Figures 12
To
adjust the tension of the air pump drive belt, loosen the adjusting
lever bolt and the pivot bolt. Move the pump in or out until the desired
tension is felt.
The tension should be checked between the air pump and the crankshaft
pulley on cars without air conditioning. On cars with A/C, the tension
should be checked between the A/C compressor and the crankshaft pulley.

Power Steering Pump
Tension on the power steering
belt is adjusted by means of an idler pulley. Turn the adjusting bolt on
the idler pulley until the desired tension is felt and then retighten
the lockbolt.
