Replace A Small Hose Before It Becomes A Big Problem

Sometimes the smallest cooling system components are the ones that can leave you stranded when they fail. The PPE 116002046 Turbo Coolant Hose is a simple but important replacement that helps keep coolant flowing properly between the turbo coolant return line and the thermostat coolant pipe on your LLY Duramax. As factory rubber hoses age, they can become brittle, crack, or soften from years of heat exposure, increasing the risk of coolant leaks at the worst possible time. Replacing this hose during cooling system maintenance is an easy way to improve long term reliability while everything is already accessible. Additionally, the durable silicone construction offers excellent resistance to the high temperatures commonly found in the engine bay. Whether you are refreshing an aging truck or completing a larger cooling system repair, this PPE hose provides the dependable fit and performance needed to keep your Duramax operating with confidence.

Designed For Reliable Cooling System Performance

Engineered for 2004-2005 Chevrolet Silverado 2500HD and 3500HD along with GMC Sierra 2500HD and 3500HD models equipped with the 6.6L LLY Duramax engine, the PPE 116002046 Turbo Coolant Hose serves as a direct replacement for the factory connection between the turbo coolant return line and the thermostat coolant pipe. The straight hose features a 10mm inside diameter, matching the original application for proper coolant flow and secure installation. Furthermore, the silicone construction is designed to withstand the elevated temperatures and harsh operating conditions found within the engine compartment while maintaining flexibility over time. The hose replaces OEM part number GM 94013117, making it a practical solution when servicing worn or deteriorated factory components. Installing a fresh coolant hose during related cooling system repairs helps reduce the chance of future leaks while supporting dependable engine and turbocharger cooling. Built by PPE, this replacement hose delivers the quality and durability that Duramax owners expect when maintaining their truck for years of reliable service.
