The Dayco 5120783 is a 12-rib automotive serpentine belt with an effective length of 1988.82 mm and a width of 42.16 mm. When you replace a serpentine belt, the part number on the old belt is the fastest way to confirm you are ordering the correct one. We supply this belt to maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America.

Start by reading the marking printed on the back of the belt you are removing. If it shows 5120783 or 12PK1990, this Dayco belt matches that profile and length. Count the ribs to confirm the number, and check that the old belt is a 12-rib unit rather than a narrower one that may have been fitted previously.

Measure the effective length only if the marking is worn or unreadable. The Dayco 5120783 is listed at 1988.82 mm effective length, so a belt measuring close to that figure with 12 ribs is the correct match. Do not rely on a general size description alone, since serpentine belts with the same rib count can differ in length.

If you are unsure, send us the part number from the old belt, or the rib count and measured length, by WhatsApp or email. Our team will confirm the right Dayco belt for your drive or suggest an equivalent, and reply with a quote.
