Key Features

Detailed Description

This Cloyes accessory drive belt kit is intended for the Nissan Altima and addresses the belt-driven components that keep the accessory drive system operating correctly. The kit is centered around a grooved black belt and standard replacement components selected for fit and function in the specified applications. Part number B40033 is used for 2007-2013 Nissan Altima coverage, with the 2013 model noted for use without electric power steering and OE exact fit.

Cloyes B40033 is a practical choice when the belt system shows wear, noise, or loss of proper tension. It supports a complete service approach rather than replacing only one worn component, which helps maintain consistent belt tracking and system operation. This part cross-references Monroe Shocks & Struts (e.g., BK4211) for the same application.

What It Is Used For

• Replacing a stretched or cracked accessory drive belt
• Addressing belt noise caused by worn drive components
• Restoring proper belt tension and pulley alignment
• Servicing the accessory drive system during preventive maintenance
• Correcting wear-related issues in the Nissan Altima belt drive system

Installation Notes and Tips

Verify the exact Altima application before ordering, since the 2013 listing includes a note for vehicles without electric power steering. Inspect related belt-driven components during installation and replace worn parts as needed to complete the repair correctly. Confirm routing and alignment after installation to ensure smooth belt operation.
