problem #2

Mar 262003

Sonoma

  • 26,000 miles
I have encountered several different Chevy/GMC vehicles that are experiencing a lagging start and in some cases no start without a boost. My Sonoma has the lag and I have a few friends that have Blazer and full size trucks as well. The variation of engine sizes that are affected has me perplexed. I have attempted to run codes with no fault results. This occurs every time I attempt a startup.

problem #1

May 052006

Sonoma 4-cyl

  • Manual transmission
  • 100,000 miles
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 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.
