PPE Power Coolant Hose Kit - GM 6.6L Duramax 2017-2019 L5P - Black 119020400

Fits: 2017-2019 GM 6.6L Duramax

Factory coolant hoses are composed of plastic Tee junctions that are prone to cracking and leaking after heat cycled. This PPE silicone hose kit completely eliminates the Tee junctions - the lower radiator hose, coolant overflow hose, and heater hose are all molded into one single piece of durable 5-ply silicone, providing maximum protection against leaking and heat fatigue. The silicone material used in this kit is far more heat resistant than the factory rubber - making it a better choice for this high-heat environment.

The CNC machined billet aluminum adapter ensures easy, OEM-like fitment onto the radiator outlet. All connections are sealed with uniform-tension 304 stainless steel clamps.
