Detailed Product Description

The Sunsong 3402231 power steering pressure line hose assembly is built with chlorosulfonated polyethylene (CSM) material, providing resistance to heat, oil, and abrasion commonly encountered in power steering systems. The hose measures 59 inches (1500 mm) in length, ensuring proper routing and connection between the power steering pump and steering gear. Both ends feature male o-ring fittings—16 mm on one end and 18 mm on the other—allowing secure, leak-resistant connections. Additionally, this assembly includes a power steering switch port, enabling integration with vehicle sensors for system monitoring.

This hose assembly is specifically compatible with Chevrolet Express 1500, 2500, 3500 and GMC Savana 1500, 2500, 3500 models, making it a suitable replacement part for maintaining hydraulic pressure and steering responsiveness in these vehicles. The absence of a bracket means it mounts directly using existing hardware in the vehicle’s power steering system.

Common Applications and Issues Addressed

• Replacement of worn or leaking power steering pressure hoses
• Restoring proper hydraulic pressure to improve steering response
• Eliminating fluid leaks that cause steering noise or difficulty
• Preventing hose failure due to abrasion or heat damage
• Maintaining sensor functionality with integrated power steering switch port

Installation Notes and Tips

• Verify hose length and fitting sizes (16 mm and 18 mm male o-ring) before installation
• Ensure power steering system is depressurized prior to hose removal
• Inspect and clean fittings to prevent contamination during installation
• Use appropriate torque specifications for fittings to avoid leaks
• Check power steering fluid level and bleed system after installation
