The Dayco 5030343 is a 3-rib automotive multi-rib (serpentine) belt with an effective length of 869.95 mm and a width of 10.16 mm. Before you fit it, inspect the drive and sheaves so the new belt runs true from the first start.
Check each sheave for wear, rust, burrs or debris in the grooves, and confirm the ribs are clean and undamaged. Spin the pulleys and idlers by hand to feel for rough bearings or excess play, and check that the tensioner moves freely through its range. A worn or misaligned sheave will shorten the life of any new belt, so correct it before installation.
Confirm the routing matches the drive layout, then seat the belt fully in the grooves without forcing it over a pulley flange. Verify that all ribs are engaged and the belt is centered on each sheave. After running the engine briefly, recheck tension and alignment.
If you are replacing a worn belt, read the marking on the back of the old belt and compare it with the Dayco 5030343. Send the part number, the belt marking and a photo of the routing to our team by WhatsApp or email, and we will confirm the match or suggest an equivalent.
