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.
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.
