Inspect the drive belt(s) every 30,000 miles (48,000 km)/24 months 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.
See Figures 1 through 5
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.
- 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.
- Adjust the belt tension by loosening the adjusting bolts.
- Next loosen any mounting bolts and/or nuts that may hinder adjustment.
3.0CL models have automatic tensioners therefore no belt adjustment is required.
- 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.
- 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.
- After obtaining the proper tension, tighten the adjustment lock bolt.
- Tighten all other bolts and/or nuts that were loosened in the adjustment process.
See Figures 6 through 13
REMOVAL & INSTALLATION
Many Acura models are equipped with a theft deterrent audio system. Make sure you have the necessary code before disconnecting the battery.
- Disconnect the negative battery cable.
- Loosen the driven accessory's pivot and mounting bolts.
If removing the alternator belt on a 3.0CL, pull back on the belt tensioner with a commercially available tool.
- Remove the belt.
- Install the belt by moving the accessory toward or away from the engine until the tension is correct. You can use a wooden hammer handle, or broomstick, as a lever, but do not use anything metallic, such as a prybar. Certain models may utilize an adjusting bolt to do this work for you. Simply loosen the mounting bolt and turn the adjuster.
On 3.0CL pull back on the tensioner to install the belt, the tension is automatically set.
- Tighten the bolts and recheck the tension. If new belts have been installed, run the engine for a few minutes, then recheck and readjust as necessary.
