I just did mine the other day.

Siphon out as much as you can from the reservoir (I used a turkey baster) and then crawl under and crack open the bleeder valve. let gravity do the job for you and then fill the reservoir with fresh fluid a couple of times. When the fluid coming out is clear, close the valve, top off the reservoir and you're done.

One final note. Don't forget to buy the wife another turkey baster. They don't wash up very good.
