• – After any service of the power steering system, always bleed the air from the system and verify proper system operation. An accurate fluid level cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise as well as pump damage over a period of time.
• – Always check the manufacturer's service information for the correct power steering fluid to use. Different fluids are specified by the manufacturer to meet the operating requirements of their power steering systems. Using the wrong fluid could cause hose and seal damage as well as fluid leaks.
• – Always follow the manufacturer's specific instructions on flushing.
• – Check your vehicle's power steering fluid levels periodically, and add fluid when necessary.
• – Flushing the system will help eliminate any residual contaminants from causing future power steering pump failure. Dirty or contaminated fluid may cause low or no pressure from the power steering pump.
