I want to flush the power steering system on 1998 Delta 88 3.8. as the fluid is sort of brown and smells burnt . What is the best way to do this ? - Thanks .

Turkey-bastering the old fluid out works. A vacuum pump with a long hose will work even better. And a funnel with a long hose to pour new fluid in.

Other people will be more specific.

I thought about that method and I guess I could do it several times to complete changing the fluid . I was wondering about a method of flushing the PS system ( remove a return line ( where / how ? ) and pouring in fresh PS fluid are the same rate as it is draining or is the more trouble than it is worth . -Thanks

I did the turkey-baster style swap. 4 times over 4 weekends will get something like 90% of it.

You can do a complete flush through the lines like you mention, but the risk of getting air trapped in the rack was too high for my taste.

draining and refilling works well enough. Heck, if everybody around here does it with the transmission sauce, it'* likely more than fine for the PS sauce.
