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 power brake booster system fails due to a loss of fluid, take the following steps before starting the vehicle:
When servicing any part of the brake system, verify the drive belt tension and condition.
When servicing any part of the brake system, check the level in the power steering fluid reservoir. Check the fluid level in the reservoir at regular intervals. Add fluid as needed. Refer to Checking and Adding Power Steering Fluid .
