Review on ๐ŸŽ๏ธ Ultimate Performance: Continental GOO49021 Idler Pulley Unleashed! by James Julien

Revainrating 5 out of 5

good price fits a 2001 Duramax

Bought to replace a pulley that was damaged when another pulley froze and snapped off. It fits a 2001 Duramax motor on a grooved idler pulley. Installation took about 5 minutes to unscrew the old pulley and screw on the new one. When replacing a belt I would also look at Goodyear belts. Your belt is a lot quieter than the old one I had on my truck.

Pros
  • Pulleys
Cons
  • not sure
