A/C Compressor Belt

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 - 11.0 mm (0.31 - 0.43 in)
New Belt: 5.5 - 6.0 mm (0.22 - 0.24 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 5 minutes or more.
- "New belt" means a belt which has been used for less than 5 minutes.

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

Tension Gauge Method




1. Attach the special tool to the A/C compressor belt as shown, and measure the tension of the belt.

A/C Compressor Belt
Used Belt: 440 - 640 N (45 - 65 kgf, 99 - 143 lbf)
New Belt: 930 - 1,080 N (95 - 110 kgf, 209 - 243 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 5 minutes or more.
