Sunsong 3403016 Power Steering Cylinder Line Hose Assembly - Cylinder
Power Steering Cylinder Line Hose Assembly
Sunsong 3403016 is a power steering cylinder line hose assembly built for precise OE-style replacement on steering systems that require a 20-inch hose with 1/4-inch male inverted flare ends. It is engineered for durable pressure handling and corrosion resistance, making it a practical choice for power steering hose replacement on select Honda Civic and Toyota Corolla applications where this configuration is specified.
Key Features
- Part number 3403016 power steering cylinder line hose assembly
- 20 in. length with 1/4 in. male inverted flare fittings on both ends
- CSM hose material for fluid and heat resistance
- Pressure-rated construction with a 1,500 psi max working pressure
- 8,700 psi burst pressure rating and 1,600 lb tensile strength
- Steel tubing with zinc electroplating for added rust and corrosion resistance
- High-pressure tested before shipment for installation confidence
Detailed Description
This Sunsong power steering cylinder line hose assembly is built to restore steering fluid transfer between system components with the correct length, fitting style, and pressure capacity. The 1/4-inch male inverted flare connections and 20-inch overall length make 3403016 a direct-fit style replacement where those specifications are required. For shoppers searching for a Honda Civic power steering hose or Toyota Corolla steering line hose, this part number 3403016 provides a specification-driven match rather than a universal fit.
Construction details matter in steering repairs, and this hose uses CSM material along with steel tubing protected by zinc plating to help resist humidity, road salt, water, and grime. That makes it a solid option for replacing a worn or leaking power steering cylinder line hose assembly on Honda Civic and Toyota Corolla vehicles when the original routing and connection style call for this configuration.
This part cross-references Dorman - HELP 80580 for the same application.
Common Problems It Can Help Solve
- Power steering fluid leaks at the cylinder line hose
- Cracked, hardened, or deteriorated hose material
- Corrosion on steel tubing or fittings
- Steering noise caused by restricted fluid flow
- Loss of steering assist from a damaged pressure line
Installation Notes and Tips
Verify the hose length, fitting type, and end size before installation. This assembly uses 1/4-inch male inverted flare ends, so matching the original connection style is important for proper sealing. Inspect adjacent brackets, grommets, heat shields, bushings, and protective sleeves on the vehicle and replace any worn components as needed during the repair.
For best results, flush contaminated power steering fluid before installing the new hose and confirm that the routing matches the original line path to avoid contact with moving or hot components.
Quality Assurance
Each Sunsong 3403016 hose is pressure tested at the factory before release to help confirm leak-free operation and consistent performance. The hose is engineered to exceed original equipment performance standards for pressure handling and durability.
