    15. Fill the power steering system with synthetic power steering fluid. We recommend Royal Purple full synthetic fluid. When filling the reservoir, do not fill to the top. Allow about 1/2" for fluid expansion due to heat. It will take some time to fully bleed the system the first time. With the vehicle on jack stands and tires completely off the ground, engine not running, turn steering wheel from lock to lock several times and then refill the power steering reservoir with fluid. Note, this is done so that the power steering pump does not get started dry, which can cause damage to the pump. Now you’re ready to start the engine and turn the steering wheel from lock to lock, we recommend that you run the motor for about 5 minutes at a time during the bleeding. Allow the oil to set until all the bubbles have separated out of the oil, then run the motor again for 5 minutes. Repeat this procedure until the oil runs without foam or bubbles.
