Detailed Product Features and Specifications

The Sunsong 3401390 power steering pressure line hose assembly features 16 mm swivel o-ring fittings on both ends, providing secure and leak-resistant connections. The hose is made from chlorosulfonated polyethylene (CSM), a material known for its excellent resistance to heat, oil, and abrasion, which is critical for maintaining hydraulic integrity under demanding conditions. With a length of 41.8 inches (1061 mm), this hose assembly is tailored to fit the power steering systems of Ford Explorer, Explorer Sport, Explorer Sport Trac, Mercury Mountaineer, and Ford Mustang models. This assembly does not include a bracket or a power steering switch port, simplifying installation where those components are not required.

Applications and Common Issues Addressed

  • Replaces worn or leaking power steering pressure hoses in compatible Ford and Mercury vehicles
  • Prevents power steering fluid leaks that can cause steering difficulty or pump damage
  • Restores proper hydraulic pressure for consistent steering performance
  • Eliminates hose swelling or cracking due to age or heat exposure
  • Helps avoid power steering pump failure caused by fluid loss or contamination

Installation Notes and Technical Tips

Installation of the Sunsong 3401390 power steering pressure line hose assembly requires proper handling of hydraulic components. Ensure the vehicle is safely lifted and the power steering system is depressurized before removal. The 16 mm swivel o-ring fittings should be inspected for damage and replaced if necessary to maintain a leak-free seal. Sunsong provides technical tips TT1000 and TT1002 to assist with installation and maintenance procedures. Since this assembly does not include a bracket, verify existing mounting points for secure hose routing.
