PPE Heater Outlet Hose 20-26 GM 6.6L Duramax L5P
Are you dealing with a cracked or worn outlet heater hose on your L5P Duramax? The PPE Outlet Heater Core Supply Hose Kit is designed to replace the weak OEM rubber hose with a heavy-duty silicone upgrade built to handle the temperatures and pressure cycles found in diesel applications. Factory coolant hoses can deteriorate over time from heat, vibration, and constant pressure fluctuations, eventually leading to leaks or premature failure. PPE’s upgraded hose kit helps improve long-term cooling system reliability while adding a cleaner, high-performance appearance under the hood. Designed as a direct-fit replacement, this kit installs easily using factory routing without cutting or modifications.
