Keep hydraulic steering assist flowing from the pump to the steering gear with the Sunsong power steering pressure line hose assembly, part number 3403612. It is a replacement for the 2005-2011 Cadillac STS. See the Buyer's Guide tab for engine-specific details.
Sunsong is a vertically integrated manufacturer focused on researching, developing and producing automotive fluid transfer hoses and lines. The company says it builds products around what installers need, aims to exceed industry quality standards rather than simply meet them, and designs for exact form, fit, and function.
- Pressure ratings: The hose is rated for a maximum working pressure of 1,500 psi, a burst pressure of 8,700 psi and a tensile strength of 1,600 lb. Sunsong states these figures exceed original equipment performance standards.
- Pre-assembled with brackets: Sunsong pre-assembles its pressure and return hoses with brackets. This is designed to make installation easier and take less labor than hoses sold individually.
- Precision engineered: The assembly is engineered to an exact fit for the listed application.
- Pressure tested: Every pressure hose goes through a high-pressure quality assurance test before it leaves the factory.
A pressure hose may need replacing if you see power steering fluid leaking or wetness at the hose or its fittings, a falling fluid level, a whining pump, or heavier steering effort. Diagnose the source first. If the pressure hose is the cause, this assembly replaces it. After installation, refill and bleed the system with the fluid specified in the vehicle's service information.
