2007.5-2010 GM HD Coolant Block-Off Plug LMM (119000100)

Description

This billet aluminum plug prevents coolant leakage from the engine oil cooler adapter during service. When you install PPE exhaust manifolds and up-pipes on a 2007.5-2010 LMM Duramax, the factory coolant tube is no longer compatible and must be removed; the block-off plug seals the oil cooler adapter in its place. It also lets you run a 2007.5-2010 oil cooler adapter on a 2007-or-earlier engine build.

Features

• Billet aluminum construction
• Seals the engine oil cooler adapter when the coolant tube is removed
• Required when fitting PPE manifolds and up-pipes

Notes

• Intended for race trucks that no longer route coolant to the EGR and cabin heater.
