Fits: 2007.5 thru 2010 Chevy Silverado/GMC Sierra 2500HD/3500HD LMM Duramax Diesel

PPE’s modified coolant tube for LMM Duramax 6.6L is designed for use with PPE Up-pipes and Manifolds. Their expert 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.

Notes:

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