2017-2019 Duramax Upper Coolant Pipe (L5P-FLU-A192)

Our Upper Coolant Pipe replaces the stock rubber hose on the L5P Duramax with a rugged stainless steel piece that looks custom and stands up to heat, vibration and repeated coolant cycles far better than the factory part. The rubber hose does its job, but once you start running higher power tunes or our compound turbo kit, your cooling system is working harder, and all that extra heat and pressure is exactly what makes rubber age, get brittle and crack over time. Swapping it out takes care of one more weak point, so along with the extra power you're building a truck that's more dependable as a whole. The smooth bends also clean up the area between the radiator and the thermostat housing for a much neater look than the bulky factory hose.

Part Number: L5P-FLU-A192
