'99 Silverado Ext Cab, 5.3
A/C serpentine belt broke at 25K and replacement Gates belt broke 10K
later. All parts connected to belt turn freely and without noise.
All components appear to be in alignment and there are not sharp
places. Belts appear to have been ripped apart and original joint
seam is intact. Anyone else having this problem. Any ideas how to
prevent this would be appreciated. These belts are expensive.
I don't know if that year of vehicle is affected, but we've had a number
of the new style trucks with compressor problems. It ends up destroying
the tensioner and sometimes throwing/breaking the A/C belt. The fix
is to replace the compressor with an updated one. I looked at your
year of vehicle to see if there were any bulletins relating to this problem,
didn't see any at the moment.
