ContiTech 49273 Accu-Drive Accessory Drive Belt Tensioner Assembly

The ContiTech 49273 Accu-Drive Tensioner Assembly is an engineered replacement for your vehicle's accessory drive belt tensioner, designed to meet or exceed OEM specifications for fit and performance. This precision-manufactured component maintains optimal belt tension throughout the life of your serpentine belt system, ensuring reliable operation of critical engine accessories.

Key Features:

• Round torsion-spring technology provides superior damping of engine vibrations compared to traditional flat-spring designs
• Automatically compensates for belt wear and maintains constant tension for extended belt life
• Integral pivot shaft and OE-style locating pins ensure precise mounting accuracy and alignment
• Patented proportional damping system reduces drive system noise and harshness
• OE-quality pulley construction ensures smooth belt travel and proper alignment
• Enhanced corrosion protection for longer service life

This complete tensioner assembly is designed as a direct replacement and includes all necessary components for installation. As a non-serviceable unit with a preloaded internal spring, the assembly should always be replaced as a complete unit rather than attempting repairs.
