2011-2016 GM 6.6L Duramax Coolant Bypass Tube - Water Pump to Thermostat Housing - Pacific Performance Engineering - 119000830

GM 6.6L Duramax Coolant Bypass Tube - LML

The OEM mild steel tube is prone to rust, which can lead to coolant system contamination and eventual leaks. Over time, factory O-rings also tend to harden and lose compression, increasing the risk of failure. PPE’s upgraded bypass tube is specifically designed to work with the factory water pump and is crafted from high-grade 304 stainless to prevent corrosion and ensure reliable, long-term performance.
