Product Details

Bando’s Rib Ace Precision Engineered V-Ribbed Belt line focuses on OE-style accuracy and durable materials for domestic and import vehicles. This belt is compounded with EPDM for longer life, while the soft backing helps reduce noise during operation. The machine-cut rib profile and bidirectional cord design are intended to maintain alignment and deliver consistent performance in accessory drive systems. This part cross-references Gates K030441 and Dayco 5030440 for the same application.

Compatible With 2001-2002 Toyota Prius, Air Conditioning and Water Pump, and 2003 Toyota Prius, Air Conditioning and Water Pump. The Bando 3PK1120 is a direct-fit option for Prius accessory drive service where the OE belt specification calls for precise metric sizing and a 3-rib configuration.

Common Problems This Belt Can Address

  • Squealing or chirping from a worn accessory drive belt
  • Belt slip under accessory load
  • Cracking, glazing, or rib wear on the existing belt
  • Noise from an aging belt backing or rib surface
  • Loss of proper drive to the air conditioning compressor or water pump

Installation Notes and Tips

Verify the OE number and belt length before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since damaged components can shorten belt life and affect tracking. Confirm the rib count and routing path match the vehicle’s accessory drive layout before final tensioning.

Quality Assurance

The Rib Ace line is engineered to exceed OE manufacturing specifications using EPDM compounding, precision rib cutting, and reinforced cord construction. For 2001-2003 Toyota Prius accessory drive applications, Bando 3PK1120 provides an OE-style replacement built for consistent fit and durable service.
