Acura 91-05 NSX AC Compressor Belt 38920-PR7-305

Genuine Acura NSX A/C Compressor Belt - 1991-2005 (38920-PR7-305)

The A/C compressor belt is a wear item that cracks and glazes with age, and on an NSX you want it kept fresh and genuine. When it goes, you lose your air conditioning, and a worn belt often announces itself with a squeal before it fails outright. This is the genuine Acura belt for the NSX A/C compressor, a 4-rib, 975mm belt that fits both automatic and manual cars across the full 1991-2005 run, so you're replacing it with the exact part Acura specified.

When To Replace It

Like any belt, this one ages whether or not you drive the car much, heat cycles and time crack and harden the rubber, so on a low-mileage NSX it can age out by the calendar rather than from use. Inspect it for cracks on the ribbed side, glazing (a shiny, hardened surface), fraying, or a squeal when the A/C compressor engages, any of those means it's due.

A failing A/C belt first costs you air conditioning, and a belt that's shedding or slipping can take out the works around it. It's an inexpensive part and a sensible thing to stay ahead of, especially if you're already in there doing the alternator belt, which ages on the same timeline.

The Correct A/C Belt For The NSX

Fitment specifics, so you get the right belt.

This is the A/C compressor belt for the 1991-2005 NSX, and unlike some belts on the car, it fits both automatic and manual transmission models. It's a 4-rib, 975mm belt, the correct profile and length for the NSX's A/C compressor drive. As the genuine Acura part, it's made to the exact spec, so it fits, tensions, and wears correctly where a generic belt might be slightly off or fail early.
