Description

The Pacific Performance Engineering Coolant Bypass Tube is a direct replacement for the factory water pump to thermostat housing connection on 2001-2005 GM 6.6L Duramax engines. Crafted from high-grade 304 stainless steel, it resists corrosion and leaks, unlike the OEM mild steel tube. This upgrade also includes two Viton O-rings for a reliable seal.
