Flushing power steering fluid refers to the process of circulating the fluid in an automobile's steering system in order to assure proper operation. At slow speeds, power steering allows you to easily turn the big, heavy wheels on your car — as long as you have enough steering fluid. The procedure is not difficult, and with a little knowledge, even someone with a minimal amount of experience in mechanics can perform this task on his or her own. | Flushing power steering fluid refers to the process of circulating the fluid in an automobile's steering system in order to assure proper operation.

#Check your owner's manual for the recommended power steering flush schedule. Your power steering system is actually remarkable at staying clean. That said, over time natural wear and tear will cause bits of rubber, plastic, and dirt to enter the fluid, and this can cause problems to the entire system if the fluid is not flushed. Each car has it's own suggested interval after which you should change the fluid, so look up your model's time frame. | #Check your owner's manual for the recommended power steering flush schedule.

#Drain the power steering fluid by disconnecting the low-pressure hose from the steering pump at its lowest point. There will be multiple thin (1/2-1" thick) hoses running from your power steering. With your pan ready underneath, unhook this hose and drain the old fluid. | #Drain the power steering fluid by disconnecting the low-pressure hose from the steering pump at its lowest point.

#Refill the reservoir to its prior level with fresh fluid. This simple procedure will protect your car, cheaply, and is just as effective a method as a full flush if you have no other problems. The power steering system is, relatively speaking, rather clean and simple. Unlike other fluids, like oil, the power steering system doesn't even need a filter. This quick "refresher" is likely all you'll need to do to keep your wheels turning easily. | #Refill the reservoir to its prior level with fresh fluid.
