Pacific Performance Engineering 119000630 Coolant Bypass Tube - Polished Stainless Steel

The Pacific Performance Engineering 119000630 is a premium coolant bypass tube designed to replace the factory plastic coolant pipe that runs from the water pump to the thermostat housing on 2001-2005 GM 6.6L Duramax LB7 and LLY engines. Constructed from polished 304 stainless steel, this upgrade eliminates the common failure point of the stock plastic tubing which can crack and leak over time due to heat cycling and engine vibration.

Key Features:

• Polished 304 stainless steel construction for superior durability and corrosion resistance
• Direct replacement for factory plastic bypass tube
• Eliminates common coolant leak issues from cracked OEM plastic components
• Precision-engineered for perfect fit on LB7 and LLY Duramax applications
• High-quality finish enhances engine bay appearance
• Withstands extreme heat and pressure cycles

This is a critical upgrade for Duramax owners looking to prevent unexpected coolant system failures. The stainless steel construction ensures this component will outlast the vehicle while maintaining proper coolant flow between the water pump and thermostat housing.
