Fitment and Application Details
Use this hose assembly when replacing the return-side steering line on vehicles that require a direct-fit replacement with the correct routing and connection points. This Sunsong 3401140 hose assembly is listed for 2000-2005 Chevrolet Impala and 2000-2005 Chevrolet Monte Carlo applications, including Impala models with cooler and excluding police and taxi configurations.
End 1 uses a 16 mm male O-ring fitting, and End 2 uses a 3/8 in ID hose connection. The hose measures 136.8 in (3473 mm) in length, which supports the original routing used in the vehicle-specific application. This part cross-references Dayco 85010 and Gates 365966 for the same application.
Common Replacement Reasons
- Leaking power steering return hose
- Cracked or hardened hose material
- Corrosion on steel line sections
- Fluid seepage at hose connections
- Restricted or damaged return-line routing
Installation Notes
Verify the vehicle’s steering configuration before installation, especially cooler-equipped applications and the listed Impala exclusions. Confirm the fitting sizes and routing against the original hose assembly before removal. Inspect related wear items such as brackets, grommets, heat shields, bushings, and protective sleeves, since this assembly is engineered to restore the original fit where those components are required.
Quality Assurance
Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-side steering service. The steel tubing is zinc electroplated to help resist rust and corrosion from humidity, road salt, water, and grime, supporting long-term durability in demanding underhood and road conditions.
