A/C Compressor

Measuring Drive Belt Deflection:

DEFLECTION
1. Apply a force of 22 lbs (10kg, 98 N) and measure the deflection between the A/C compressor and crankshaft pullies.
Compressor Belt Deflection:
Used Belt: 0.26-0.41 in (6.5-10.5 mm)
New Belt: 0.20-0.31 in (5.0-7.0 mm)

P/S Belt Deflection:
Used Belt: 0.31-0.47 in (8.0-12.0 mm)
New Belt: 0.24-0.37 in (6.0-9.5 mm)

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 A/C adjust pulley nut and the adjusting bolt.
3. Turn the adjusting bolt to get proper belt tension, then retighten the bolt and nut.
4. Recheck the deflection of the belt.

Measuring Drive Belt Tension:

TENSION
1. Measure with Belt Tension Gauge: Attach the belt tension gauge to the belt and measure the tension of the belt.

Compressor Belt Tension:
Used Belt: 77-110 lbs (35-50 kg, 343-490 N)
New Belt: 132-176 lbs (60-80 kg, 588-784 N)

P/S Belt Tension:
Used Belt: 77-110 lbs (35-50 kg, 343-490 N)
New Belt: 110-154 lbs (50-70 kg, 490-686 N)

NOTE:
- If there are cracks or any damage evident on the belt, replace it with a new one.
- See the instructions for the tension gauge.

2. Loosen the A/C adjust pulley nut and the adjusting bolt.
3. Turn the adjusting bolt to get proper belt tension, then retighten the bolt and nut.
4. Recheck the deflection of the belt.
