Oiwa Garage Tech Note
"Match the belt to your compressor - the title notes the compressor it fits. With the belt off, check the A/C fluid while you have easy access. Set a new belt to 35-60 kgf. It beds in to 22-40 kgf, so recheck after a short run."
Frequently Asked Questions
Which compressor does this fit?
Compressor 100. Enter your vehicle VIN/chassis number at checkout (example HA4-1234567).
How do I check the A/C belt?
Twist it to inspect for cracks and glazing, then check tension with a gauge. A used belt should read 22-40 kgf. A squeal when the A/C engages usually means the belt is loose or glazed.
How tight should the A/C belt be?
Set a new belt to 35-60 kgf on a tension gauge. A used belt runs at 22-40 kgf, so a fresh belt beds in and loses a little tension. Recheck after a short run. Too loose squeals when the compressor loads, too tight wears the bearings.
How often should the A/C belt be replaced?
Replace it at 68,000 km (42,000 miles), the same interval as the alternator belt, so most people do both together. Check the A/C fluid while the belt is off.
