The Dayco 5050661 is an automotive multi-rib serpentine belt with 5 ribs, a 17.27 mm width and a 1679.96 mm effective length. Before fitting it, inspect the drive and sheaves so the new belt runs true and wears evenly.

Start with the sheaves. Look for grooves worn into a V, nicks on the ribs, rust or debris packed into the pulley grooves, and any pulley that turns roughly or has play. A sheave in poor condition will damage a new serpentine belt, so correct it before installation. Confirm the routing matches the drive layout and that the tensioner and idler spin freely.

The belt is identified by its marking: Dayco 5050661, with 5PK1680 as an alias. It has 5 ribs, a 17.27 mm width and a 1679.96 mm effective length. Compare these values with the belt you are replacing. If the old belt is stretched, glazed or has missing ribs, note the condition and check the alignment of the accessories it drives.

When you request a quote, send the part number 5050661 or the alias 5PK1680, plus the quantity and any drive details you have. We carry Dayco belts and can confirm the profile and length from the marking on your old belt.

If the drive shows uneven wear, misalignment or a noisy bearing, address those points before fitting the new belt. A clean, aligned drive helps the 5-rib belt seat correctly and run quietly.
