To change power-steering fluid, siphon out the old fluid, and refill the reservoir with a fluid recommended by your car's manufacturer after flushing the system. You need a siphon bulb or turkey baster, an empty container, a quart of power-steering flush and power-steering fluid.
- Prepare the reservoir and empty container
Locate the power-steering fluid reservoir, and unscrew the cap. Ensure the container is ready to accept the fluid.
- Insert the siphon into the reservoir
Insert the tip of the turkey baster or siphon bulb into the reservoir. If you are using a siphon bulb, insert the other end into the container.
- Remove the old fluid
Squeeze the handle of the siphon, and transfer the fluid from the reservoir and into the container.
- Start the engine, and fill the reservoir with power-steering flush
Turn on the engine, and fill the reservoir to the full line with power-steering flush. Allow the engine to run with the flush for 10 seconds.
- Remove the flush, and repeat
Siphon out the flush until the reservoir is empty. Repeat until a quart of power-steering flush has been used.
- Fill the reservoir with new fluid
With the engine still on, add a little power-steering fluid to the reservoir. Check the dipstick to see if the fluid is over the minimum line. If not, add more fluid. Do not exceed the maximum line.
