How to partially change power steering fluid

[flounderfilet]

I have a 2005 Corolla LE with 53,000 miles. Never changed fluid before and it is currently very dark. I heard you can use a turkey baster to suck out half and refill. The owners manual recommends I use automatic transmission fluid Dexon 2 or 3. Does this make sense? Thanks.

Dexron III.

I don't know if the reservoir design changed after 2003, but I couldn't get a turkey baster down into mine. I had to disconnect one of the hoses and turn the engine over to pump out the fluid (we're talking only a few seconds of engine turning).

Reconnected the hose and filled it back up. Wheel turns a bit smoother and the pump isn't as loud as it was.

Your fluid is red to begin with, so "dark" fluid isn't necessarily a big deal unless it's not red anymore.

I believe my PS reservoir cap said Dexron IV, I could be wrong though. after I did my tranny swap I put in my leftover mobil 1 ATF (dex. IV equivalent) in my PS system. we used a long, large syringe to suck out as much of the old fluid as we could.

I used an old coolant tester, gets in there almost perfect or if you have a old turkey baster you can attach some clear tubing on the end to suck it up...I used Lucas Power Steering Fluid with Conditioners, sucked out half/filled then ran my car a while then did the same, works and runs great

If you also want to change the brake fluid by bleeding, I would suggest invest a vacuum pump like this:

Instead of a partial change, you can do a full exchange like Trd mentioned. Of course you can do a partial exchange and keep diluting the old fluid, say at every oil change.

I easily replace all the power steering fluid without a suction pump... Jack up the front, remove front left wheel, unhook lower PS hose on rack+pinion and drain in a bucket. Attach a hose (~1/2" ID) to rack+pinion fitting, with the other end of hose into bucket. Remove small hose in front of PS fluid reservoir which is now empty (1st hose you drained), and plug the hole. Start filling reservoir with new fluid which flows through pump and rack+pinion, as old fluid comes out attached hose. Keep filling reservoir while turning steering wheel all the way back and forth a few times. Reinstall bottom hose when fluid comes out clean and red. Remove plug and quickly rehook hose on reservoir, then fill up to max cold line. Turn steering all the way both sides a couple times and keep refilling to bleed air out. It takes almost a quart.
