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.
Take the following steps before starting the vehicle if the hydraulic brake booster system fails due to the loss of the fluid:
| • | Make all of the necessary repairs. |
| • | Fill and bleed the hydraulic brake booster system. Refer to Hydraulic Brake System Bleeding . |
Clean and flush the hydraulic booster system before replacing the power steering pump. Metal shavings from a worn power steering pump contaminate the system. Disassemble and clean the booster head. Replace all of the seals and the O-rings. Remove the pipes and the hoses. Blow clean all of the metal shavings from the pipes and the hoses. Refer to Hydraulic Brake System Flushing . Refer to Power Brake Booster Replacement .
