Detailed Description

Apex AVC396S is an engine valve cover gasket set for vehicles listed in the fitment data, including Chevrolet Colorado, GMC Canyon, Hummer H3, and Isuzu i-350 applications.

Installation Notes and Tips

Confirm engine configuration and fitment before installation, especially on 2004-2006 Chevrolet Colorado and 2004-2006 GMC Canyon models. Clean the sealing surfaces thoroughly and inspect the valve cover for warpage, cracks, or contamination before installing the new gasket set. Verify that the application calls for grommets and spark plug tube seals, as listed in the fitment notes for this part.

Quality Assurance
