PPE Power Coolant Block-Off Plug Duramax (LMM) - 119000100
When installing PPE Exhaust Manifolds and Up-pipes, the factory coolant
tube is no longer compatible. Intended for race trucks that no longer have
the need for coolant to flow to the EGR and cabin heater. The Coolant
Block-Off Plug is installed in place of the coolant tube.
