ContiTech K49250C Poly-V Serpentine Belt & Tensioner Kit

The ContiTech K49250C is a complete Poly-V serpentine belt and tensioner kit, engineered to replace all critical accessory drive components in a single service. Bundling the serpentine belt with a matched tensioner and idler pulley, this kit eliminates the guesswork of sourcing individual parts and helps prevent premature system failure.

Kit Includes:

• Serpentine Belt: 6-groove Poly-V design, 85.50 in. length, 0.83 in. width
• Smooth Surface Steel Idler Pulley: 3.54 in. outside diameter, 0.670 in. bore, 1.19 in. wide
• Automatic belt tensioner assembly

Key Features:

• Advanced EPDM rubber compound virtually eliminates chirps, squeaks, and squeals associated with pulley misalignment
• Polyester tension member specially treated to reduce elongation and control belt stretch
• Tensioner features patented proportional damping system tuned to absorb engine vibrations and reduce drive system noise
• Accu-Drive tensioner technology maintains near-constant belt tension, maximizing accessory drive component life and preventing belt slip
• OE-style locating pins and pivot shaft ensure precise mounting accuracy and alignment
• Meets or exceeds OEM fit and performance standards

Why Replace as a Kit?

Continental belt drive components are engineered to work as a system. Replacing individual components can lead to uneven wear, belt slippage, and loss of tension. Replacing the belt, tensioner, and idler together at the same time protects against complete accessory drive system failure and costly repairs down the road.
