Built for a More Durable Oil Line Repair

This engine oil cooler hose assembly addresses a common failure point on GM trucks and SUVs where the original rubber inlet and outlet hoses can harden, crack, or burst from heat and pressure. Dorman 625-340XD uses PTFE and braided stainless steel construction to provide a more robust replacement for the factory oil cooler hose assembly. It is a direct-fit solution for vehicles such as the 2005-2006 Chevrolet Silverado 1500, 2005-2006 GMC Sierra 2500 HD, and 2005-2006 Cadillac Escalade, as well as 2007 Chevrolet Silverado Classic and 2007 GMC Sierra Classic models.

This part cross-references GM 15809049 for the same application.

Common Problems This Part Can Address

• Oil leaks from brittle or cracked cooler hoses
• Burst inlet or outlet lines caused by heat and pressure
• Loss of oil pressure from damaged cooler hose assemblies
• Oil contamination around the engine oil cooler line routing
• Repeat failures from aging rubber hose construction
