Adjusting tyiming belt - 2002 Honda Odyssey

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.

1. Push down on the belt halfway between pulleys with a force of about 20 lbs. The belt should deflect: 0.16-0.41 in. (4-11mm)-on Integra and 0.22-0.45 in. (5.5-11.5mm) on all other models.
2. Adjust the belt tension by loosening the adjusting bolts.
3. Next loosen any mounting bolts and/or nuts that may hinder adjustment.

3.0CL models have automatic tensioners therefore no belt adjustment is required.

1. To adjust the alternator belt tension on Integra, loosen the adjustment lock bolt and move the alternator with a prybar positioned against the front of the alternator housing.

WARNING Do not apply pressure to any other part of the alternator or damage may occur.

1. To adjust the tension on all other accessory drive belts (all Acura models except 3.0CL), loosen the adjustment lock bolt and turn the adjusting bolt (if applicable) as required.

Do not over tighten any of the belts. Damage to the pulley's bearings may result.

1. After obtaining the proper tension, tighten the adjustment lock bolt.
2. Tighten all other bolts and/or nuts that were loosened in the adjustment process.

alternator and air conditioning compressor

1. Disconnect the negative battery cable.
2. Loosen the idler pulley bolt.

The replacement of the inner belt on multi-belted engines may require the removal of the outer belts.
To replace a drive belt, loosen the adjusting and mounting bolts of the component which the belt is driving. Move the component inward to relieve the tension on the drive belt.
Slip the belt off the component pulley and match the new belt with the old belt for length and width. The old belt will be slightly longer. After a new belt is installed correctly, adjust the tension.

1. Turn the adjustment bolt at the top of the idler pulley bracket. Clockwise rotation will tighten the belt; counterclockwise will loosen it.
   
2. Keep the idler pulley bolt snug (but not tight) while adjusting belt tension. The adjustment bolt should turn with moderate force.

After adjustment is satisfactory, tighten the idler pulley bolt, and then tighten the adjustment bolt.

Reconnect the negative battery cable.

When replacing more than 1 belt, it is a good idea to make note or mark what belt goes around what pulley; this will make installation easier if you mix up the belts.
