The factory-original belt that drives the AC compressor on my '00 Chrysler 300m decided to disintigrate recently (first the inner 1/2 separated and got shredded in amongst the pulleys and then the outer 1/2 got noisy so I had to cut it and remove it).
This belt is behind the serpentine belt, so I figured I might as well
replace both of them. A local parts store was offering the Goodyear
Gatorback as a replacement.
The defining characteristic of these "gatorbacks" is that they have
diagonal notches cut into them for some reason.
Here's a few pictures:
I asked the parts guy why would I want a belt that was made
intentionally weaker by having some of the belt material removed by
cutting these notches on the inside. He said these were premium belts
and the notches help to clear dirt from getting into or staying in the v
grooves. I told him I didn't buy that argument, and the addition of
these notches would make the belt noisier.
Note the package:
"The quite belt"
Quiet my ass. You put those notches on the side of the belt that
contacts the pulley or the v-grooves, you're going to have noise. The
notches are at a bit of a diagonal so maybe that cuts down on some
I had them order me some "normal" belts that haven't been intentionally
weakened by the notch-cutting.
Anyone have the same (or different) take on these belts?
A google search seems to turn up some reports and pictures of early
failure of these belts...
