Integra & 2001-04 RL Models
  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).
  2.  
  3. Adjust the belt tension by loosening the adjusting bolts.
  4.  
  5. Next loosen any mounting bolts and/or nuts that may hinder adjustment.
  6.  
  7. 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.

  8.  
  9. To adjust the tension on all other accessory drive belts, loosen the adjustment lock bolt and turn the adjusting bolt (if applicable) as required.
    NOTE
    Do not over tighten any of the belts. Damage to the pulley-s bearings may result.

  10.  
  11. After obtaining the proper tension, tighten the adjustment lock bolt.
  12.  
  13. Tighten all other bolts and/or nuts that were loosened in the adjustment process.

Inspection



The maintenance intervals suggested by the manufacturer vary by time, operating conditions (normal or severe), and mileage. A good rule of thumb is to inspect the drive belts every 15,000 miles (24,000 km) or 12 months (whichever occurs first). On manually adjusted multi-ribbed V-belts, measure the belt tension at a point halfway between the pulleys by pulling or pressing on the belt with a known force and measuring how far the belt moves, referred to as the amount of deflection. Note that deflection is not free-play, but the ability of the belt, under actual tension, to stretch slightly and give. The specification for measuring belt tension includes the amount of force applied to the belt, and the amount of defection (movement) the belt should have when the force is applied. The amount of deflection varies depending on whether the belt is new or used. Although the manufacturer markets a specific tool for measuring belt deflection, a fisherman-s spring scale capable of measuring a 22 lb. (98 N) pull and a small ruler can be substituted for this tool.

Inspect the belts for the following signs of damage or wear: glazing, cracking, fraying, crumbling or missing chunks. A glazed belt will be slightly brittle and perfectly smooth from slipping, and may exhibit a screeching noise when the engine is suddenly accelerated or first started. A good belt will have a slight texture of fabric visible and the surface should be soft and flexible. Cracks will usually start at the inner edge of a belt and run outward. A belt that is fraying will have the fabric backing de-laminating itself from the belt. A belt that is crumbling or missing chunks will have missing pieces in the cross-section of the belt, some times these chunks will be stuck in the pulley groove and not easily seen. 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.

Although it is generally easier on a component to have the belt too loose than too tight, a loose belt may place a high impact load on a bearing due to the whipping or snapping action of the belt. A belt that is slightly loose may slip, especially when component loads are high. This slippage may be hard to identify. For example, the generator belt may run okay during the day, and then slip at night when headlights are turned on. Slipping belts wear quickly not only due to the direct effect of slippage but also because of the heat a slipping belt generates. Extreme slippage may even cause a belt to burn. A very smooth, glazed appearance on the belt's sides, as opposed to the obvious pattern of a fabric cover, indicates that the belt has been slipping.

Both multi-ribbed V-belts and serpentine belts can be checked for wear by inspecting the physical condition of the belt. To check belt stretch on multi-ribbed V-belts, look at the amount of adjustment that remains on the sliding portion of the adjustment bracket, or the threaded portion of the adjustment screw. If the adjustment range has is at its fully extended portion, the belt should be replaced.

Serpentine drive belts should be inspected for rib chunking (pieces of the ribs breaking off), severe glazing, frayed cords or other visible damage. Any belt which is missing sections of 2 or more adjacent ribs which are 1 / 2 in. (13mm) or longer must be replaced. You might want to note that serpentine belts do tend to form small cracks across the backing. If the only wear you find is in the form of one or more cracks are across the backing and NOT parallel to the ribs, the belt is still good and does not need to be replaced.
