I have the UR (underdriven) pulley set on my 03 G. Using Gates belts, but they seem to stretch a week after I adj them and the squeek on startup. The AC belt is stretched to the point I can no longer adj. Anyone else having this problem??? Any suggestions, or recommendations would be appreciated.

 

I've had the whole set on my car for over a year with the same belt. It did take a few adjustments initially to get it all set and not squeaking, but I haven't had to adjust it for over a year either.

 

Squeeking will occur b/c of glazing of the belts by the soft aluminum. If they are really stretched or cracked, they probably need replacement

 

Gates belts? All i know is i used the Nissan belts that came with it when I had it, no problems. I don't know if it's gates you should be using, I might be wrong, as for the squeek, that is NORMAL, after I got it installed, they told me I might here squeaking within 1-2 weeks, come back or I can tighten it my self, it squeaked after 3 weeks, i just came back and they adjusted it, since then no problems.
