Keep power steering fluid moving back to the reservoir with the Sunsong power steering return line hose assembly, part number 3402392. It is a direct-fit replacement for the 2006-2008 Buick Lucerne. See the Buyer's Guide tab for engine details. The return line carries fluid on the low-pressure side of the system, routing it from the steering gear back to the reservoir so the pump can recirculate it.
- Rated to 250 psi: Sunsong return hoses exceed original equipment performance standards, carry a maximum working pressure of 250 psi, and are suited to low-pressure, high-temperature operation.
- Precision-engineered assembly: Built for exact fit and supplied with the additional components required, intended to bring the wearable parts back to original condition.
- Corrosion-resistant tubing: The tubing resists rust and corrosion from high humidity, road salt, water, and grime.
- Pressure-tested: Each return hose goes through a high-pressure quality assurance test before it leaves the factory.
Sunsong is a vertically integrated company that researches, develops, and manufactures automotive fluid transfer hoses and lines. It designs its products around what installers need, with a focus on exact form, fit, and function.
Signs a return hose may need replacing include fluid seeping from the hose or its fittings, a cracked or swollen hose, and a steadily dropping fluid level. Pump whine from low fluid can also occur. Confirm the source of a leak before replacing parts.
