Serpentine belt chirping
Hi Folks. '05 H2 w/177,000 miles
I put on a new NAPA belt (NBH 25060930-$40.00) months ago and it started chirping again within a week. I troubleshooted with water and soap, Figured replacing the upper tension pulley(was bad)... replaced exact same belt under warranty and its chirping again after another week or so.
That spray bottle diagnosis quiets down at the water-pump pulley, but i'm wondering if anyone is having issues with this NAPA belt quite often.
I Replaced water-pump a year ago and done the AC belt on the day I'm talking above. Would trying a different store belt be a good idea as the next fix attempt?
Thanks for any input.

Phil has it right.... They are not called Gatorback (now Continental Elite) anymore though. The hand down best belts you can get are the Continental Elite belts.
Main belt
AC belt
Could very well be a pulley though. There is the static idler pulley plus the pulleys on everything else that could have a bearing going....
I did just re-read that you did change the waterpump a year ago. Cheapo one or AC Delco or some other good brand? I know the cheapest stuff for something like that is something to avoid due to inferior quality, particularly in things like bearings. However it could be any one of the assorted drive bearings like on the tensioner, idler, power steering pump, etc. Realistically the best way to id something like this is to use a mechanics stethescope with the long tube rod and probe down by each of the accessory drives and pulleys and see if you can narrow it down to a specific one.
Could very well just be a poor quality belt as well though.

I think i'll give that a try. I looked around all the pulleys to see if anything else was causing the problem. The motor block pulley appears to shimmy a slight bit, but none of this started until I thought replacing the belts might be good idea since the power-steering pump was being change.
It doesn't chirp when idling- No change in loudness...
I'll look for where I can purchase the belt referred by you two helpful folks and post back the outcome.
Thanks again for advice.

We did use a stethoscope to find the upper tensioner seemed a problem. However, It all started with a new power steering pump, but the chirp wasn't down there.
Is that main belt you posted the exact fit for my 05 H2 base model 6.0?
My sister works at Amazon and I can get it with less hassle on me.
