Route high-pressure fluid from the pump to the steering gear with the Sunsong Power Steering Pressure Line Hose Assembly (P/N 3402345), a direct-fit replacement for the 2003-2004 Cadillac CTS. Built by a vertically integrated maker of automotive fluid-transfer hoses and lines, it comes pre-assembled and ready to install in place of a leaking, chafed, or corroded original.
- Pre-assembled with brackets: the pressure and return hoses ship with brackets already fitted, easing installation and cutting labor time versus hoses sold individually.
- Complete kit: precision-engineered to fit and includes the additional components needed to restore wearable parts to original condition.
- High-pressure capability: the pressure hose carries a max working pressure of 1,500 psi, a burst rating of 8,700 psi, and 1,600 lb tensile strength for durability and long service life.
- Factory-tested: every pressure hose passes a high-pressure quality-assurance test before it leaves the plant for trouble-free installation and operation.
Signs the original line may need replacing include power-steering fluid leaks, whining or groaning from the pump, and hard or uneven steering. If a failed pressure line is the cause, this assembly replaces it.
