How can I flush the PS fluid in my 07 F150?

 

Just suck out what you can and refill it.

 

With like a turkey baster straight from the reseviour? How do I ensure I get it all out?

 

A turkey baster works. I used a wet dry vac and a narrow funnel..

 

Why do you want to get all the old fluid out? I've never flushed a power steering system in over 40 years of working on vehicles. The only reason I'd ever do it is if the cap had been left off and dirt and water got into the system.

 

If you are experiencing a little pump moan add a half bottle of friction modifier-Motorcraft 8 oz bottle.

 

Because I just didmy 06 Duramax with 50k miles and the fluid was black and the steering and brake response is noticebly better now.

 

They do work better with fresh fluid. My van had never been changed and it had over 200k on it,figured it was due and it did make it quieter..

 

Is there not a better way to drain/flush than simply pulling some of the fluid out of the reservoir with a turkey baster or vacuum?!?! I had my oil changed at the dealership today and they said my power steering fluid was brown. I want to change it out.

 

Not really.

 

Not much need to do more than what's in the reservoir...there's probably only a few ounces throughout the rest of the system and what you get out doesn't justify the pain/mess of getting it out.

Im also in the club that every vehicle I've changed the fluid in has made a substantial noticeable difference in feel and performance. Used Amsoil ATF also, even in my speed sensitive Lexus it made a difference.

 

There is a Ford process in the shop manual that involves disconnecting the "inlet" hose from the bottom of the resivoir and plugging the hole that it comes off of (I used a new pencil with a cut up inner tube from the kids bike). Then route the hose to a bucket, open the resivoir and DON'T let the resivoir go empty. Start the engine and turn the wheels from side to side. This will pump old fluid into the bucket, have a helper keep the resivoir full while you keep turning the wheels, don't stay turned to the stops as this applies too much pressure. When you see fresh fluid go into the bucket, you are flushed. Reconnect the line and top off the fluid. In rare cases, air can be trapped in the line like in the brake lines. If this happens, you need a vacum to pull the air to the resivoir.

Your welcome.

 

Yea, I disconnect the line as well, - flushed her out good. Didn't have enough Amsoil on hand so I used RP instead. She hasn't complained since and still looks like fresh fluid. The old stuff was pretty spent. I wasted a new quart of fluid flushing her out, but it was worth it IMO.
