The Dayco 5100749 is a 10-rib automotive serpentine belt with an effective length of 1902.97 mm and a width of 35.05 mm. It is used on accessory drives where a single multi-rib belt turns the alternator, power steering pump, water pump, or air conditioning compressor. To confirm fit, match the rib count, effective length, and width to the belt you are replacing.
Serpentine belts like this Dayco unit are common on engine front-end accessory drives. The 10-rib profile and 1902.97 mm effective length identify the belt's path and pulley coverage. Because accessory layouts vary, the most reliable check is to read the marking on the back of the old belt and compare it to the part number and dimensions here.
When replacing, inspect all pulleys for wear, misalignment, or debris, and check the tensioner and idler bearings. A belt with the correct rib count and length can still perform poorly if the drive has a worn component. If the old belt is missing or unreadable, measure its effective length and count the ribs before ordering.
For a quote, send the part number 5100749, the rib count, and the effective length. If you are unsure, our team can help confirm the right belt or suggest an equivalent based on the data you provide.
