Help! Just replaced a power steering pump on a 73' Pontiac Grand Am. The old pump was leaking badly and I had started the motor up several times with no fluid in the reservoir. Now that the new pump is on I have great amounts of air in the system. I've tried the old way of bleeding by turning the motor on for a couple of seconds and turning the steering wheel from left lock to right lock. Done this 20 or 30 times and the pump still fills with foam in just a couple seconds of running time. Is there something else I can to do bleed the air out of the system? If I continue with this method I've been performing will I ever get the air out of the system? Thanx.
