Sunsong 3401189 power steering pressure line hose assembly for the 2001-2003 Toyota Highlander carries pressurized fluid in the power steering system.
Fluid seeping at the hose or its fittings, or a cracked or bulging hose cover, can mean a pressure hose is wearing out. Before replacing it, look the hose and both ends over with the engine off and cool, since a wet spot can also come from the pump, the steering gear or a loose fitting.
This hose assembly is a direct-fit replacement for the 2001-2003 Toyota Highlander.
