Product Details

Nissens 891505 is an A/C compressor designed around critical wear components such as the pulley, clutch, hub, bearing, and wobble plate. That design focus supports consistent refrigerant pumping and helps control operating noise and vibration under demanding conditions. For buyers servicing older Mazda RX-7, Mazda 626, or Mazda B2000 applications, the 891505 offers a fitment-specific replacement option built around OE-style specifications.

This part cross-references Gates 5725 and Global Parts Distributors LLC 6511421 for the same application. The 891505 part number appears across multiple interchange listings, making it easier to match the correct compressor when replacing an existing unit on compatible Mazda, Subaru, and Renault platforms.

Common Issues This Part Can Address

• Loss of A/C cooling from compressor wear
