Hello,

I have an 03 Chevy Trailblazer. I have replaced the tensioner belt at least 9 times in the past 2 months!!! The water pump had a bad bearing, and that has been replaced. The tensioner arm was also replaced, and I got a month of driving without any issue once this was replaced. However, The belt continues to shred! I have had several ppl look at this, and they cannot think of what is wrong with it. Any ideas...?

 

Either an alignment issue (I assume the serpentine belt) or something rubbing on it. Closely inspect for alignment or interference with the belt with engine running. DO NOT STICK HANDS FACE ECT. IN THE ROTATION OF THE ENGINE/BELT!

 

Hello,
Nothing seems to be out of alignment, and there is nothing that is interfering with the belt while the engine is running. I had 3 mechanics look at the pulleys, and they seem to be fine (not loose, in place). When the engine is running, the serpentine belt does not move, jump the ribs/notches. I tired both sizes for the belt, and they still keep shredding on the same side (the side closest to the engine/alternator, and not the side closest to the fan...if this makes sense). Always shreds on this side.

 

Hello. I too have an 03 TB and started experiencing the exact same issues. I was just wondering if you were able to figure out how to fix it. Any help will do. Thanks

 

One of the accessories that the serpentine belt turns is likely creating some drag that is wearing the belt out. Take the belt off and check all the accessories and make sure they turn freely.
