PPE Raw 304 Stainless Steel Engine Coolant Return Pipe (2004.5-2005 GM 6.6L Duramax) - (119001100
Overview
PPE's 304 Stainless Steel Engine Coolant Return Pipe is a direct replacement for the factory mild-steel pipe used on 2004.5-2005 GM 6.6L Duramax engines. Designed to work with the OEM thermostat housing, this upgraded pipe improves durability and helps maintain reliable coolant flow.
Corrosion-Resistant 304 Stainless Steel
The stock coolant return pipe is known to rust and eventually leak. PPE solves this issue with a 304 stainless steel construction that resists corrosion far better than the OEM design, making it ideal for both automotive and marine environments.
Engineered for Proper Fitment
This pipe is specifically designed to integrate with the factory thermostat housing and supports installation of the OEM turbo coolant return thermostat. Fitment and alignment match the stock component for a smooth, trouble-free installation.
Reliable Upgrade for Demanding Use
Whether used on a daily-driven truck, a tow rig, or a marine application, this stainless return pipe offers improved longevity and eliminates the common failure points found in the OEM mild-steel tube.
