Serpentine Belt
The idler pulley on my 2015 Ford E350 with the Triton V10 with A/C is chirping. 43,000 miles on it. So I figure while I'm changing the idler I'll replace the belt. A friend of mine who is a mechanic...

I guess it's never too late to teach an old dog new tricks. Following up on the information I had from years ago which I posted above, I find that Dayco has replaced their line of Polycog belts with Dayco Poly Rib Gold Label belts. I found this statement on https://www.bobistheoilguy.com/dayco-qa/
Dayco has been in business for over 105 years and also makes a quality product right here in the USA supply belts to the OEM market.

Poly-cog belts were designed to improve overall durability by increasing the flexibility of the belt as it bends around accessory pulleys. Dayco’s new Poly Rib W profile belts are not cogged, but use a new rubber formulation, EPDM, which increases the overall durability without the cogs, and improves the noise resistance of the belt by allowing the rib tips to flex whenever entering misaligned pulleys. Poly Cog belts were designed and introduced to the aftermarket in 1989 based on the serpentine drives and belt technology that existed at that time. The Poly Rib W profile belt was first introduced in 2007 and incorporated the newest rubber formulations along with the improved rib profile, designed to flex and conform in worn aftermarket drives.
