Notice: Do not run the engine without fluid in the power steering pump reservoir. Doing so could damage the pump bearing and seals. The belt that drives the power steering pump also drives the coolant pump and other components. Do not disconnect the belt and run the engine. A malfunctioning power steering pump and/or system still serves as an idler pulley for the belt. If the pump is allowed to run without fluid in it, the bearings will seize up and cause the coolant pump to stop. This can cause damage to the engine.
If the hydraulic booster system fails because of a fluid loss, take the following steps before starting the vehicle:
- If the failed component is not the power steering pump, route the pressure pipe back to the fluid reservoir.
- Make all necessary repairs.
- Replace the power steering fluid.
- Bleed the power steering system. Refer to Power Steering System Bleeding in Power Steering System.
Metal shavings from a worn power steering pump often contaminate the system. If you replace the power steering pump, clean and flush the hydraulic booster system. Refer to Power Steering System Flushing in Power Steering System. Remove the pipes and hoses. Refer to Power Brake Booster Inlet Hose Replacement or Power Brake Booster Outlet Hose Replacement in Power Steering System. Blow the pipes and hoses clean of all metal shavings.
