Continental 4040329S Serpentine Belt - Air Conditioning

Overview

Continental Multi-V Stretch Belt 4040329S is a fixed-drive accessory belt built for air conditioning applications that require a stretch-fit design. It uses low modulus and high elongation construction to install without a tensioner on the specified applications, while EPDM rubber and a polyamide tensile cord support stable operation.

• Stretch-fit Multi-V design for fixed drive systems
• EPDM rubber construction for accessory drive use
• Polyamide tensile cord for added belt strength
• 4-rib profile with a 0.55-inch top width
• 32.90-inch belt length for specified applications

Detailed Description

This Continental serpentine belt is part of the Multi-V Stretch Belt line, which focuses on stretch-fit accessory drive applications that do not use a conventional tensioner. The belt’s low modulus and high elongation construction helps it seat on fixed drive systems, and the OEM-oriented EPDM compound is paired with a polyamide tensile cord for consistent belt structure. Part number 4040329S is used in Subaru air conditioning applications, including WRX STI, Forester, Impreza, and WRX fitments.

Compatible With Subaru WRX STI, Subaru Forester, Subaru Impreza, and Subaru WRX air conditioning drive applications. If you are replacing a worn Subaru serpentine belt in these configurations, 4040329S matches the specified stretch-belt setup. This part cross-references Subaru 11718AA082 and 23979AA000 for the same application.

What It Solves

• Cracked or glazed accessory drive belt surfaces
• Noise from a worn stretch belt
• Loss of belt grip in air conditioning drive service
• Incorrect fitment on fixed-drive stretch-belt applications

Installation Notes

Use only on the listed stretch-belt applications. If a stretch belt is removed for any reason, it must be replaced on the specified Subaru applications. Verify belt length, rib count, and routing before installation. Part number 4040329S should be matched to the vehicle’s air conditioning drive configuration before service.

Quality Assurance

Continental designs this belt with OEM-level material technology, including EPDM compounds and a polyamide tensile cord, for the specified accessory drive applications.
