Continental 4040357S Elite Poly-V Stretch Serpentine Belt 4-Rib 36.1"

The Continental 4040357S is an Elite Poly-V Stretch Serpentine Belt engineered for accessory drive systems that lack a mechanical tensioner or adjustment slot. Unlike standard serpentine belts, this stretch belt uses advanced low modulus and high elongation technology to self-tension once installed, maintaining consistent belt tension throughout its service life.

Key Features:

• Belt Type: Elite Poly-V Stretch (OETS) — identified by the "S" suffix in the part number
• Outside Length: 36.1 inches
• Cross-Section Width: 0.56 inches
• Rib Count: 4 ribs
• Construction: EPDM compound with polyamide tensile cord for superior heat, ozone, and wear resistance
• Profile: Cogged Poly-V (Multi-V) design
• Self-Tensioning: Stretches for installation on fixed drive systems, then recovers to maintain proper tension without a mechanical tensioner
• True OEM-grade materials and engineering — Continental is a major OE supplier to domestic and foreign vehicle manufacturers

Important: The Continental 4040357S Stretch Belt is not interchangeable with standard Poly-V or conventional serpentine belts. Always verify the application requires a stretch-fit belt before installation.

Continental's OE Technology Series brings factory-level fit, form, and function to the aftermarket, making the 4040357S a reliable, direct OEM replacement for qualifying accessory drive systems.
