Key Features

The Sunsong 3405086 pressure hose assembly is built around exact-fit replacement requirements for Chevrolet Impala and Chevrolet Impala Limited models. It uses high-grade steel tubing with a zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. The hose is pressure tested before it leaves the factory to support reliable installation and operation.

This part cross-references Dorman - HELP 81012 and Gates 352625 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
• Corrosion-related hose failure on vehicles exposed to road salt and moisture
• Noise or erratic steering feel linked to restricted or deteriorated hose flow
• Fitment issues from a replacement line that does not match OE routing

Installation Notes and Tips

Verify the end fittings before installation: End 1 uses an 18 mm male O-ring fitting and End 2 uses a 16 mm male O-ring fitting. Confirm the hose length and routing against the original line on the vehicle before tightening connections. Inspect mating surfaces, seals, and surrounding steering components for wear or contamination during service.
