Keep power-steering fluid moving under pressure with the Sunsong Power Steering Pressure Line Hose Assembly 3401990, a direct-fit replacement for the 2006-2007 Buick Terraza, 2006-2009 Chevrolet Uplander, 2006-2009 Pontiac Montana, and 2006-2007 Saturn Relay (see the Buyer's Guide tab for engine-level fitment). This assembly carries pressurized fluid from the power-steering pump toward the steering gear, and worn or leaking factory lines commonly show up as fluid weeping at the fittings, low reservoir level, or a whine and heavy steering effort.
- Pre-assembled with brackets: the pressure and return hoses ship together with their brackets for easier installation and reduced labor versus individual replacement hoses.
- Complete kit: precision-engineered to fit and includes the additional components needed to restore wearable parts to original condition.
- High-pressure rated: the pressure hose exceeds original-equipment performance standards with a 1,500 psi max working pressure, an 8,700 psi burst rating, and 1,600 lb tensile strength for long life.
- Factory-tested: every pressure hose is subjected to a high-pressure quality-assurance test before leaving the factory.
Sunsong is a vertically integrated manufacturer of automotive fluid-transfer hoses and lines trusted by OEMs.
