Gates Accessory Drive Belt P/N:2/5VX800
Silence belt squeal and keep the fan and alternator turning with the Gates Accessory Drive Belt 2/9670PB. This belt carries rotation from the crankshaft over to the fan and alternator, and it drops in as a direct-fit replacement for the 1988-1990 Chevrolet B60, 1989-1991 GMC B6000, 1989-1993 Mack RB, and the 1990-1993 Mack RD, Mack RM, and Mack RW.
A worn belt often shows up as squealing or chirping on startup, glazing, cracking, or fraying. If a failing belt is the cause of those signs, replacing it with this belt restores the drive path to the fan and alternator; diagnose the underlying condition first, since noise or charging issues can also come from the tensioner, pulleys, or accessories themselves.
