My powersteering groans terrible on cold mornings and if i try and drive it if it hasnt warmed up for 5 or 10 minutes, it will shoot the fluid out. has anyone else had this problem? now I got some valvoline synthetic blend im gonna put in it now, so what is the best way to get all of the old stuff out? will sucking out the reservor be enough, or is there a better way to get all of it out and would i need to get it all out?

 

Synthetic Dexron III/Mercon ATF is the best power steering fluid IMHO. I would think that you could take the return line off the pump and drain it that way. Maybe crank the engine over without starting it, and add new fluid to flush the old out.

 

How cold? I don't have too much experience in the cold but I do know that disolved water will boil in a brake line. Will it freeze in power steering fluid? just a left field guess. I went into an interstate median with no brakes (including parking brake) as a result of overheated motor/ bad brake fluid... BTW, the parking brake was rigged IAW specs...

 

i guess im not sure how cold, maybe like 5-10 degrees. usually whenever it high idles the power steering whines (seems like every morning in south dakota). i guess i never thought about getting water in it, i will drain it and add that synthetic and see what happens

 

turkey baster method worked good for me, only took bout 10 min. to remove old fluid......yeah i know i didnt get it all out.......i dont care.
