Kent-Moore EN-49761 GM Valve Stem Seal Installer
Applications: GMT900 C/K Silverado/Sierra; GMT610 G-van Express/Savana
EN-49761 installs the new MY 2010-I valve stem seal to a specified height. MY2010-I Duramax diesels will not have a retaining groove for the new-style valve stem seal on the guide boss. EN-49761 will work with the valve in place (on-vehicle) or out of the head.
