2005 Chevy Colorado Z85 4x4 Standard Cab

The fan motor has been running for a week now and works great. This eliminated the factory engine squeak and replaced the rubber hose on the factory engine. You will need a 5.5mm jack, a 1/4" U-joint and various extensions for installation. I also recommend replacing the wiring harness with a new one from GM and cleaning the ground point on the passenger wheel well.

Pros
  • Best in Niche
