The Dayco 5120788 is a 12-rib automotive multi-rib (serpentine) belt with a 2000 mm effective length and 42.16 mm width. Before you fit it, inspect the drive and sheaves so the new belt runs true from the first start. We carry this belt and quote by part number.
A serpentine belt that fails early often traces back to the drive, not the belt. With the old belt off, check each sheave for wear, nicks, or buildup in the grooves, and confirm the ribs are clean and uniform. Misalignment between pulleys will pull a 12-rib belt sideways and wear the edges. Spin the idlers and tensioner by hand and listen for roughness. Any play or noise should be addressed before the new belt goes on.
The Dayco 5120788 is a 12-rib belt, 2000 mm effective length, 42.16 mm wide. Match those numbers to the belt you are replacing, and route it per the drive layout. Keep the belt seated fully in every groove before you apply tension. After the engine runs, recheck the tracking and tension.
