i didn't closely inspect my drive belts but i saw many small cuts (like the look when a rubber is too stretched) on the belts.
The car has 41000 miles and i think it's the time to replace them(?)
I heard good and bad reviews on Goodyear Gatorback belts but mostly positive ones. So i'm going to give this a try since i hate to buy from dealers.
But i can't find the part numbers. Can someone provide me part numbers on Goodyear Gatorback belts both A/C and alternator belts? Which website to buy from?
I looked up on summitracing but 350zs don't show under drive belts.

thanks.

 

Goodyear Poly-V Gatorbacks:

A/C: 4040372
Alt P/S: 4060465

FWIW, Gates sell very good belts as well.

 

i think it was from 350ztech.com where i saw someone saying gatorbacks are upgraded version(?) of Gates. Less squeal and all that. Oh, also he/she said that gatorbacks have wider belts than OEM. How does that affect our engine>?

EDIT: i tried again and found belts on summitracing. Do any mechanic shops or auto parts store carry these?

 

i got my gatorbacks from Schucks (oreily now)

 

autozone carries gatorback
oriellys carries gates.

 

Thx. i'll check autozone out

 

If these were available for my HR, I'd buy one:
