One problem related to engine belts and pulleys has been reported for the 1999 GMC Sonoma. The most recently reported issues are listed below.
Not sure if belt broke first or fan blade the blade broke off and flew inside of truck causing damage to parts under the hood it was 1000. 00 to fix all the parts broken by this. I have all the old parts. The belt was ok but something caused the blade to brake off and there are noticeable cracks in the blade around the nut. Because of this failure I had to replace a lot of components under the hood.
