The Dayco 5120903 is a 12-rib automotive multi-rib (serpentine) belt with an effective length of 2292.35 mm and a width of 42.16 mm. It is used on accessory drives where a single Poly-V belt turns multiple pulleys such as the alternator, power steering pump, water pump and air conditioning compressor. To confirm fit, match the rib count, effective length and width to the original belt or the vehicle's drive diagram.
Because serpentine belts route over several pulleys, the rib count and effective length must match exactly. This belt has 12 ribs and measures 2292.35 mm in effective length, with a width of 42.16 mm. Check the marking on the back of the old belt, or measure the old belt and compare it to these figures before ordering.
Inspect the drive system at the same time: worn tensioners, misaligned pulleys or a leaking water pump can damage a new belt quickly. If the old belt is stretched or the part number is unreadable, send the vehicle details and a photo of the routing diagram to our team. We carry the Dayco 5120903 and can help confirm it is the right belt for your application.
