Buyer's Q&A

Frequently Asked Questions

Is this Dayco serpentine belt right for the 2005-2007 Peterbilt 357 11.1L or 12.5L?

Yes. Dayco 5081020 fits the 2005-2007 Peterbilt 357 with either the 11.1L or the 12.5L engine. For any other model, open the "Vehicles it fits" section and check your exact engine.

Is a Dayco fan belt the same as this serpentine belt?

Yes, for this part. Dayco 5081020 is a serpentine belt whose position covers the fan, the alternator, air conditioning and the main drive.

Is this serpentine belt made of EPDM?

Yes. It is EPDM with aramid reinforcement, in a K-section profile with straight ribs and standard rib depth.

What temperature range and standards does the Dayco 5081020 belt cover?

It operates from -45°F to 212°F (-42.7°C to 100°C) and is built to SAE J1459 and SAE J2432.

How can I tell if my serpentine belt is worn?

With the engine off and cool, look for cracks or fraying along the ribs. A squeal while driving is another sign, and a shop can test the rest of the belt drive.
