Turbo Coolant Return Hose, Front, Duramax LB7 | 2001-2004
This is the genuine GM front turbo coolant return hose assembly, GM part number 94002821, for the 2001-2004 6.6L Duramax LB7. The LB7 turbocharger is cooled by engine coolant, and this hose is part of the return path that carries coolant away from the turbo and back into the cooling system.
Key Features
- Genuine GM part number 94002821 (GM name: Hose Asm, Turbo Coolant Return, Front)
- Front turbo coolant return hose
- Direct replacement for the factory LB7 hose
Benefits
The turbo coolant hoses live next to one of the hottest parts of the engine, and years of heat cycles harden the rubber until it cracks or seeps at the connections. A leaking return hose loses coolant and drips it onto hot turbo and exhaust components. An OE hose matches the factory shape and connections, so it routes clear of the turbo without kinking.
Fitment
Fits 2001-2004 Chevrolet Silverado and GMC Sierra 2500HD and 3500 with the 6.6L Duramax LB7. For 2004.5-2005 LLY trucks, use the Turbo Coolant Return Hose, 2004.5-2005; for 2006-2010, use the Turbo Coolant Return Hose, Duramax 2006-2010.
