Compressor HVAC: Adjustments

A/C Compressor Belt Adjustment-Deflection Method:

Deflection Method
1. Apply a force of 98 N (10 kgf, 22 lbf) and measure the deflection between the A/C compressor and the crankshaft pulley.

A/C Compressor Belt
Used Belt: 8.0 - 10.5 mm (0.31 - 0.41 in)
New Belt: 4.5 - 6.5 mm (0.18 - 0.26 in)

NOTE:
^ If there are cracks or any damage evident on the belt, replace it with a new one.
^ "Used belt" means a belt which has been used for five minutes or more.
^ "New belt" means a belt which has been used for less than five minutes.

2. Loosen the upper mounting bolt and the lower mounting nut of the alternator.
3. Turn the adjusting bolt to get proper belt tension, then retighten the lower mounting nut and the upper mounting bolt.
4. Recheck the deflection of the A/C compressor belt.

A/C Compressor Belt Adjustment-Tension Gauge Method:

Tension Gauge Method
1. Attach the belt tension gauge to the A/C compressor belt as shown below, and measure the tension of the belt.

A/C Compressor Belt
Used Belt: 490 - 590 N (50 - 80 kgf, 110 - 132 lbf)
New Belt: 1030 - 1130 N (105 - 115 kgf, 231 - 254 lbf)

NOTE:
^ If there are cracks or any damage evident on the belt, replace it with a new one.
^ Follow the manufacturer's instructions for the belt tension gauge.
^ "Used belt" means a belt which has been used for five minutes or more.
^ "New belt" means a belt which has been used for less than five minutes.

2. Loosen the upper mounting bolt and the lower mounting nut of the alternator.
3. Turn the adjusting bolt to get proper belt tension, then retighten the lower mounting nut and the upper mounting bolt.
4. Recheck the tension of the A/C compressor belt.
