Dayco 89362 Automatic Serpentine Belt Tensioner Assembly

The Dayco 89362 No Slack Automatic Belt Tensioner is engineered to maintain constant tension on your serpentine belt throughout its service life. Featuring flat spring technology, this tensioner allows for an increase in torque to be transmitted to the belt when needed, compensating for stretch and wear while maintaining constant tension. This precision-engineered component resolves common belt issues including squeal, improper tracking, and accessory failures.

Key Features:

• Deflected Arm Plate that decreases rotational movement and extends tensioner life
• Locator pin built to withstand maximum drive demands and correctly locate the tensioner for installation
• Heavy-duty cast aluminum spring case to resist cracking and rust while delivering quieter performance and longer service life
• Flat wire spring construction allows for internal tension to be concentric, providing constant tension
• Durable cast aluminum housing and arm with steel locator pin and arm plate
• Counter-clockwise rotation with 74mm diameter pulley and 39.25mm width
