Detailed Description

Sunsong 3402788 is a power steering pressure line hose assembly designed for specific Chevrolet Colorado and GMC Canyon suspension applications. It uses CSM hose material and steel tubing with a zinc coating to help resist rust and corrosion from humidity, road salt, water, and grime. The assembly measures 41.8 inches in length and includes a 3/8 in male end and a 16 mm male O-ring end for the listed fitments.

This part cross-references Gates 365906 for the same application. If you are replacing a worn or leaking pressure hose on a 2004-2005 Chevrolet Colorado or 2004-2005 GMC Canyon, part number 3402788 provides a direct replacement option built to OE-style dimensions and connection points.

Common Problems This Part Can Address

• Power steering fluid leaks from a cracked or corroded pressure line
• Steering effort that increases when the hose can no longer hold pressure
• Noise or foaming caused by a damaged pressure hose assembly
• Rust-related deterioration on exposed steering line tubing
• Fitment issues when replacing an incorrect or worn hose on Colorado or Canyon models

Installation Notes and Tips

Verify suspension configuration before ordering, since this hose is listed for Colorado and Canyon models with Z71, Z85, or ZQ8 suspension. Confirm the end fittings match the vehicle connection points and inspect surrounding brackets, grommets, and heat protection during replacement. Flush the power steering system if contamination is present, and check for leaks after installation.

Quality Assurance

Each Sunsong 3402788 hose assembly is pressure tested at the factory before it leaves production. The design uses corrosion-resistant tubing and exact-fit engineering to support trouble-free installation and reliable operation on the specified Chevrolet Colorado and GMC Canyon applications.
