I did the timing chains on our 2001 last year. When I did that I also replaced the idler, tensioner and serpentine belt with a Dayco Poly rib. It squealed a badly when the truck was cold and has been getting progressively worse. I bought another one looking for a cog style but was informed that Dayco doesn't make cog style belts any more, just poly rib. It too squealed when I put it on today. I brought it back and got a refund. I then tried the old school solid rib Gates made Napa belt. Nice and quiet, not a squeak.
I am not liking the poly rib belts.
