Detailed Product Overview

This engine oil drain plug is engineered to match the original thread pitch and sealing style used on select GM compact and hybrid applications. The pilot point inset gasket design and included O-ring help support a consistent seal at the oil pan drain opening, while the steel body and Grade 5.8 construction provide a serviceable replacement for routine maintenance.
