PPE Power 116111810 Features:

PPE’s modified coolant tube for LMM Duramax 6.6L is designed for use with PPE Up-pipes and Manifolds. Our experts cut, reposition and weld the coolant tube for proper clearance. The coolant that flows through the tube provides heat to the heater core for the in-cab AC/Heat system.

Installation Disclaimer: Fully install the gasket side of the tubing first then position the bracket on and finish the installation for proper fitment.
