Product Details

The Dayco E040312 Poly Rib Belt is a high-quality serpentine belt engineered for reliable power transmission in multiple-accessory drive systems. Constructed with aramid reinforced EPDM compounds, the Dayco poly-V serpentine belt delivers more than just OE quality.

Key Features:

  • Made of EPDM (Ethylene-Propylene-Diene-Monomer) for long service life
  • Rib profile engineered to conform to high mileage, worn or misaligned drives and help eliminate noisy belt conditions
  • Offers extensive flexibility and longer service life, while handling higher workloads and temperature
  • Meets or exceeds SAE J1459 and SAE J2432 specifications
  • Multi-ribbed design enhances power transmission efficiency and reduces slippage compared to traditional belts

This serpentine belt powers critical engine accessories including the alternator, air conditioning compressor, power steering pump, and other components. Designed for demanding automotive applications, the Dayco poly rib belt provides superior performance and durability in both high-temperature and heavy-duty operating conditions.

so far the experience has been great!

Good

so far, so good

Web page was user-friendly. 20% off shipping was very cool. Combined price +shipping was lower than competitors for this part.

Great online shopping experience.

I was able to pay with Amazon pay. Excellent choice! This was on a Hummer H2. I replaced all of the 12v adapter rings. They all slide on to place exactly like the broken stock ones. I also like the chrome trim ring for it. I would have liked to have found ones that had the spring associated with the flip up cover, but these do not have the spring. I know they make them, I just couldn't find anywhere that sold them.

Easy shopping, however the confirmation from the warehouse and then the shipment to my home, took a week. For an overall product purchase it's fine, but if you have your car broken and you are waiting for the part, the waiting time is terrible.

i've been to 5 different sites 2 of them were major parts carriers, none of them had the correct parts in stock.

It was fast and easy.
