      Description

      Upgrade Your Cooling Pathway for Better Flow and Reliability. The PPE Coolant Bypass Tube; Water Pump to Thermostat Housing replaces the stock bypass routing with a purpose-built tube that improves coolant flow between the water pump and thermostat housing. Cooler, more efficient circulation helps your Duramax manage heat better under load, reducing stress on the cooling system during towing, heavy use, or hot-weather operation.

      Durable Construction Built for Long Life. Manufactured from robust materials designed to resist corrosion, heat, and vibration in the engine bay, the PPE Coolant Bypass Tube; Water Pump to Thermostat Housing stands up to real-world use. Its sturdy build helps prevent swelling, splitting, or premature failure, common weak points with stock rubber hoses, so your vehicle’s coolant path maintains performance mile after mile.

      Supports Better Thermal Stability Under Load. By smoothing the transition between the water pump and thermostat housing, the PPE Coolant Bypass Tube; Water Pump to Thermostat Housing helps your engine maintain more consistent coolant flow and temperature control. This improved stability can reduce heat soak and enhance engine longevity, especially during long hauls or heavy towing where cooling demands are highest.

      Installation. Putting this PPE Coolant Bypass Tube; Water Pump to Thermostat Housing on your vehicle takes 1 hour to install.

      Warranty. There is a 1-year limited warranty on this product.

      Application. The PPE Coolant Bypass Tube; Water Pump to Thermostat Housing fits 2011-2016 6.6L Duramax Chevrolet Silverado 2500 HD models.
