The Dayco 5050855 is an automotive multi-rib (serpentine) belt with 5 ribs, a width of 17.27 mm and an effective length of 2171.7 mm. It is used on engine accessory drives where a single belt routes around the alternator, water pump, power steering pump or air conditioning compressor. To confirm fit, match the rib count and effective length to the belt you are replacing.

This belt is identified by its 5 ribs and 2171.7 mm effective length. The effective length is measured along the belt's pitch line, so it is the correct figure to compare against the old belt or the drive specification. Width is 17.27 mm. The part number 5050855 and the alias 5PK2170 both refer to this belt.

When confirming fit, read the marking on the back of the old belt and compare the rib count and length. If the old belt is worn or the marking is unreadable, measure the effective length and count the ribs directly. A belt with the same rib count but a different length will not route correctly, and a belt with the same length but a different rib count will not seat in the pulleys.

This is a serpentine belt for automotive accessory drives, not a timing belt. Inspect the pulleys for wear, misalignment or contamination before installing a replacement. If you are unsure which belt your drive uses, send the part number, rib count and length to our team by WhatsApp or email and we will help confirm the right belt or suggest an equivalent.
