Q: power steering fluid

A power steering fluid service should be done every 3-4 years. It was once an overlooked service but like any other fluid service (engine oil, transmission fluid, etc), the more frequently you change it, the more life you will get out of the lubricated components. The correct way to do it is: First empty the power steering fluid reservoir with some sort of suction device. Once emptied, refill with the correct fluid. You will have to loosen one of the hydraulic hoses to the pump and run the vehicle. Run the engine and allow the dirty fluid to slowly bleed into a container. Make sure you keep an eye on the fluid level. DO NOT let the fluid level get too low while bleeding or you risk damaging the power steering pump and rack & pinion. Stop the engine when the reservoir gets low and refill with fresh fluid. Do this until the fluid runs out clean. Be sure to dispose of the old fluid properly. Most chain-type auto parts stores will recycle used oil/fluids free of charge.
