Litens 19 431 998 Accessory Drive Belt Tensioner Assembly - 19 431 998

The Litens 19 431 998 is an accessory drive belt tensioner assembly engineered to maintain consistent tension on the serpentine belt throughout the accessory drive system. As the world's largest original equipment (O.E.) supplier of power transmission products, Litens designs this tensioner to meet or exceed original equipment form, fit, and performance specifications.

Key Features:

• O.E.-Quality Construction: Manufactured by the original equipment supplier to ensure proper form, fit, and performance
• Round Spring Technology: Internal torsion/round spring design provides constant belt tension and proper alignment throughout the tensioner's service life
• Internal Damping Design: Reduces belt vibrations caused by engine firing pulses for quiet, smooth accessory drive operation
• Automatic Adjustment: Self-adjusting design compensates for belt stretch and wear over time, keeping the belt correctly aligned and functioning effectively
• Belt-Wear Indicator: Indicator markings warn of excessive belt stretch, signaling when belt replacement may be necessary
• Durable Pulley: Heavy-duty pulley construction for long service life and reliable performance
• Installation Instructions Included: Packaged with step-by-step installation guidance

Since belt removal is required during tensioner replacement, it is recommended to replace the drive belt at the same time to extend overall accessory drive system life and reduce total labor costs. The Litens 19 431 998 tensioner is a direct, confidence-inspiring replacement that restores proper belt tension and protects engine accessories.
