• High-grade steel tubing with zinc electroplating for corrosion resistance
• Precision-engineered hose assembly for exact fit
• End fittings: 14 mm banjo and 16 mm male O-ring
• Hose material: CSM
• Length: 65.6 in. (1666 mm)

Detailed Description

This Sunsong power steering pressure line hose assembly is built to restore pressure delivery between the pump and steering gear on covered Mazda 626, Mazda MX-6, and Ford Probe vehicles. The hose construction is designed to handle demanding steering-system pressure while the steel tubing and zinc coating add resistance to rust, road salt, moisture, and grime. Sunsong 3401845 also follows the original routing and fit requirements for applications that replace both upper and lower pressure line hose assemblies where noted.

This part cross-references Gates 367620 for the same application. Sunsong 3401845 is a direct-fit steering hose replacement for 1993-2002 Mazda 626 pump to gear, 1993-1997 Mazda MX-6 pump to gear, and 1994-1997 Ford Probe power steering pressure line service.

Common Problems This Part Can Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Loss of steering assist caused by pressure loss in the line
• Noise or stiffness from restricted fluid flow in the steering circuit
• Corrosion-related hose or tube deterioration in high-humidity or salt-exposed climates
• Fitment issues when replacing both upper and lower pressure line hose assemblies on covered vehicles

Installation Notes and Tips

Verify end fitting type and routing before installation: this assembly uses a 14 mm banjo end and a 16 mm male O-ring end. Confirm the vehicle application, steering layout, and pump-to-gear routing against the original hose before removal. Inspect related seals, mounting points, and surrounding components for wear or corrosion so the replacement line seats correctly and maintains proper steering system pressure.

Quality Assurance

Each hose is pressure tested before it leaves the factory to confirm proper operation and installation readiness. Sunsong builds this hose to exceed original equipment performance standards for pressure capacity and durability, with materials selected to support long service life in demanding steering applications.
