Q: How to inspect and adjust the drive belt and tension for the Honda CRX?
A: Inspect the drive belt(s) every 30,000 miles (48,300 km)/24 months. Determine the belt tension at a point halfway between the pulleys by pressing on the belt with moderate thumb pressure. The belt should deflect about 1/4 In. (6mm) over a 7-10 In. (178-254mm) span or 1/2 in. (13mm) over a 13-16 in.(330-406mm) span, at this point. If the deflection is found to be too much or too little, perform the tension adjustments. Before adjusting, inspect the belt to ensure it is not cracked or worn and that its surfaces are free of grease and oil. Push down on the belt half way between pulleys with moderate force. The belt should deflect approximately 1/2 in.(13mm). Deflection should be slightly less with a new belt as tension is lost rapidly for the first1/z hour or so of operation. If the belt tension requires adjustment, loosen the top mounting bolt and then turn the adjusting nut outboard of the alternator. This will reposition the alternator without prying. When the belt tension is correct tighten the upper mounting bolt to about 16ft lbs.(24 Nm). Recheck the tension, correcting the adjustment if necessary. Do not apply pressure to any other part of the alternator. To remove the belt, loosen the component-to-mounting bracket bolts. Rotate the component to relieve the tension on the drive belt. Slip the drivebelt from the component pulley and remove it from the engine. If the engine uses more than one belt, It may be necessary to remove other belts that are in front of the one being removed. To install, reverse the removal procedures. Adjust the component drivebelt tension to specifications.
