2001-2016 Duramax PPE Billet Aluminum Air Bleeder Screw (513081000)

People know that billet aluminum is a lot tougher than plastic. That toughness means fewer problems over time. So replace your fragile plastic, factory air bleeder screw with the longer-lasting billet aluminum PPE Air Bleeder Screw.

The damage and distortion that typically happens with a plastic screw from under hood temperatures and routine servicing will no longer be a problem because PPE’s Air Bleeder Screw features billet aluminum construction and a Nitrile O-ring seal.
