Detailed Description

Sunsong 3401203 is a power steering pressure hose assembly for the 2004-2006 Acura TL. It is built to meet original equipment performance expectations with a maximum working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and tensile strength rated at 1,600 lb. The hose uses high-grade steel tubing with zinc electroplating for added resistance to corrosion from humidity, road salt, water, and grime.

This Acura TL power steering pressure line hose assembly is precision engineered for exact fitment and includes the required PS switch port. The design supports proper steering system routing and helps maintain consistent hydraulic pressure in the power steering circuit. Part number 3401203 also cross-references Four Seasons 55166 and 92156 for the same application.

What This Hose Helps Address

  • Power steering fluid leaks from a worn or damaged pressure line
  • Loss of steering assist caused by pressure loss in the hydraulic circuit
  • Noise or stiffness related to restricted fluid flow
  • Corrosion-related hose deterioration from road salt and moisture
  • Fitment issues from an incorrect or poorly matched replacement hose

Installation Notes and Tips

Verify the end fittings before installation: 18 mm male captive O-ring on one end and 16 mm male inverted flare on the other. Confirm the 59.8 in. hose length and PS switch port location match the original routing on your Acura TL. Inspect adjacent steering components, seals, and mounting points before installing the new hose to help ensure a clean repair.

Quality Assurance

Each Sunsong pressure hose is pressure tested at the factory before shipment to confirm proper operation and installation readiness. The construction is intended to deliver durable service in demanding steering system conditions.
