Power steering fluid

[oj88]

Is this complete flush and fill? The Shell station that i go to uses vacuum to suck out the old fluid lang from the reservoir.

Complete flush.

Suck out as much of the old fluid as you can from the reservoir. Remove the return hose from the reservoir and attach it to a clear container. Start the engine and you'll see the old fluid flow into the container. This is done while new fluid is being poured in the reservoir and another person is turning the steering wheel lock to lock. As soon as you see clean fluid coming into to the container, the process is complete.

Return everything to how they were and just top off afterwards.
