Designed for high mileage multiple-accessory drivesthe Dayco® “W” profile belt (patent pending) is the most innovative advancement in multi-rib belt design in over 25 years. Developed through extensive laboratory and actual road mileage testing, this unique rib profile has been specifically Dayco® engineered to conform to high mileage, worn or misaligned drives without a sacrifice in quiet, long-lasting performance. The "W" profile cut into the tip of each rib makes the tip more flexible and eliminates belt chirp when the belt enters a worn or misalligned pulley. Constructed with Aramid reinforced EPDM compounds, the Dayco® “W” profile belt delivers more than OE required quality...it delivers the solution to troublesome drive problems. Dayco® Poly-Rib® Belts meet or exceed SAE J1459 and SAE J2432 specifications.

Customer Questions
Can a serpentine belt cause smoke?
Yes, a serpentine belt can cause smoke. A serpentine belt is an essential component of a vehicle's engine system. It drives various accessories such as the alternator, power steering pump, water pump, and air conditioning compressor. If the serpentine belt becomes worn, damaged, or misaligned, it can cause friction and generate smoke.
Why is my serpentine belt squealing?
The serpentine belt can squeal due to various reasons, including tension issues, worn-out belt, or a problem with the belt's pulleys.
Is my serpentine belt too tight?
If your serpentine belt is causing issues like excessive noise or accelerated wear on the pulleys, it may indicate that the belt is too tight.
Why did my serpentine belt come off?
Serpentine belts can come off due to factors such as belt wear, improper tension, misaligned pulleys, or a faulty tensioner.
