Power Steering Pressure Line for Pontiac GTO

This Sunsong power steering pressure line hose assembly is built for 2005-2006 Pontiac GTO applications and is engineered to restore proper hydraulic steering performance. Part number 3402571 is made to match the original routing and connection style for a direct-fit replacement.

  • Fits 2005-2006 Pontiac GTO
  • Power steering pressure line hose assembly for hydraulic steering systems
  • 16 mm male O-ring fittings on both ends
  • 91.5 in. overall length for application-specific routing
  • CSM hose material for durability in demanding underhood conditions
  • Cross-references Four Seasons 75045 and Gates 365677 for the same application

Built for Pressure and Corrosion Resistance

Sunsong 3402571 is designed as a replacement pressure hose for the Pontiac GTO power steering system. The hose assembly uses high-grade steel tubing with a zinc-plated finish to help resist rust and corrosion from humidity, road salt, water, and grime. It is pressure tested before leaving the factory and built to meet demanding steering-system pressure requirements.

What This Hose Helps Address

  • Power steering fluid leaks at the pressure line
  • Loss of steering assist from a damaged hose
  • Cracked, worn, or corroded original pressure tubing
  • Improper hose sealing at the male O-ring connections
  • Noise or steering effort caused by restricted hydraulic flow

Installation Notes

Verify end fitting size and type before installation: both ends use 16 mm male O-ring connections. Confirm routing and length against the original hose on the vehicle, especially on 2005-2006 Pontiac GTO models. Inspect surrounding steering components, seals, and fluid condition during replacement to help ensure proper operation after installation.

Quality Assurance

Every Sunsong pressure hose is high-pressure tested at the factory before shipment. According to the manufacturer, this hose assembly is engineered to exceed original equipment performance standards for pressure capacity and durability. Part number 3402571 is built for consistent fitment and dependable steering-system service.
