Description

The industry standard recommendation is to replace the automatic belt tensioner, and often any idler pulleys, simultaneously with the serpentine belt itself. While modern belts can last between 60K and 100K miles, the tensioner’s internal components, like the spring and bearings, experience the same high-mileage stress. Component manufacturers often design the tensioner and idler pulleys to have a similar service life, frequently covering approximately two belt replacement cycles.

Since the labor required to access and replace the tensioner is largely the same as the labor needed for the belt, addressing both components at once is a significant cost-saver. Ignoring the tensioner means that a worn spring or failing bearing could quickly cause a brand-new belt to slip, glaze, or be thrown off the pulley system entirely. Replacing the tensioner is considered preventative maintenance that safeguards the investment in the new belt.

We have created complete accessory drive kits, which bundle the belt, the tensioner and any necessary idler pulleys. This approach ensures the entire system is refreshed with components engineered to work together, restoring optimal performance and tension specifications.
