What would be the simplest way to replace steering fluid?

[sqa]

Today I was told that my Mazda Protege has dirty steering fluid and was offered to change it for 89 CAD. OUCH!!!
Is there a simplest way to replace it (at least partially until summer), outside (on my drive-way) with -10C outside (it is a winter in Canada already).

Thanks

no real "easy" way . undo the line and blow it out ( into a container) with low pressure compressed air . or .. a turkey baster but tbh unless you dip your finger in it and it feels gritty it can wait till spring. all the oil change shops use a vac-extractor which will MAYBE get about 30% of the fluid out

Thanks, will wait then.

Never did it, but I figure you remove the return line, stick it in a container, start the car and turn the steering wheel from one end to the other... should spit it all out...

how much of this fluid in there?
Thanks.

Manual would tell you...found it: 0.85 US quarts or, you being Canadian, 0.8 litres!
And actually the engine doesn't need to be running...

Thanks a lot gentlemen, you saved 90 + taxes bucks for me. I am very appreciate it. Happy new year. Armageddon 2012 will not touch you for your kindness. (LOL)
