Detailed Description

Cloyes B40050 is an accessory drive belt kit built for specific-fit service on the Buick LaCrosse, Pontiac Grand Prix, Chevrolet Impala, and Chevrolet Monte Carlo. It is intended for accessory drive systems where belt condition, pulley alignment, and tension control all affect performance. The grooved belt design and standard replacement grade make it a practical choice for restoring a worn serpentine belt drive system. This part cross-references Monroe Shocks & Struts (e.g., BK5313) for the same application.

For buyers searching for a Buick LaCrosse accessory drive belt kit, Pontiac Grand Prix serpentine belt replacement, or Chevrolet Impala belt drive service part, B40050 provides a direct-fit solution for the listed applications. The kit format supports a more complete repair approach by addressing the belt-drive system as a whole rather than replacing only one worn component. The part number B40050 is also useful when verifying the correct Cloyes accessory drive belt kit for your vehicle.

What It Helps Address

• Noise from a worn or glazed accessory drive belt
• Belt slippage caused by stretch or loss of tension
• Tracking issues from worn belt-drive components
• Vibration in the accessory drive system
• Premature wear from aging belt-drive parts
