Dorman Engine Oil Cooler Hose Assembly 625-209 — Direct-Fit for GM Trucks & SUVs, Durable Leak Repair

The Dorman 625-209 engine oil cooler hose assembly is a direct-fit replacement that restores proper oil flow between the engine and oil cooler on compatible GM trucks and SUVs.

This replacement hose assembly is engineered to match the fit and function of the original equipment, helping repair leaks and reestablish reliable oil circulation. It’s manufactured from durable materials and inspected to meet quality standards so it can be installed without specialty tools. Before ordering, use the vehicle garage tool to confirm exact fitment for your model and trim to avoid compatibility issues.

How does this hose assembly restore oil circulation?

When the factory hose fails, oil flow to and from the cooler can be restricted or leak, raising engine stress. The Dorman 625-209 kit replaces the worn or damaged lines with a matched assembly that routes oil exactly as the original system intended. Proper fit and sealing reduce the chance of leaks and help the oil cooler perform as designed.

• Direct-replacement design for original routing and connection points
• Factory-style fittings to ensure a secure seal at mating surfaces
• Durable hose materials resist oil, heat, and normal engine vibration

Will this part fit my Cadillac, Chevrolet, or GMC model?

The 625-209 assembly covers a range of GM full-size trucks and SUVs from model years listed for each vehicle family. Compatibility depends on year and trim, so confirmation via the garage tool and the Confirmed Fit indicator is recommended. If an information icon appears, review its notes to verify your vehicle’s exact configuration.

• Compatible families include Escalade, Avalanche, Silverado, Suburban, Tahoe, Sierra, and Yukon
• Model years span mid-2000s through early 2010s for many variants
• Always check trim and engine options in the vehicle lookup before purchase

How difficult is installation and what tools are required?

Installation is straightforward for anyone with basic mechanical experience and common hand tools. Dorman designs the assembly to match original connections so special tools are typically unnecessary. Still, plan for routine precautions: drain the oil as needed, use proper torque on fittings, and replace any related seals if they show wear.

• No specialty tools usually required; basic hand tools suffice
• Follow safe steps: relieve pressure, contain any oil drainage, and dispose of fluids properly
• Inspect mating surfaces and replace seals or clamps if compromised

What are the construction and quality features of this replacement line?

Dorman builds this hose assembly from materials chosen to resist oil exposure, heat, and the mechanical stresses of engine operation. Each part undergoes quality checks to ensure fitment and function are consistent with product specifications. The result is a long-lasting repair option when the original hose shows cracking, swelling, or leaking.
