Power steering hose size

Power steering fluid flush

Ok, slight update...

Flushed my power steering juice using this method (post#2):
Changing Power Steering Fluid - advice needed - Toyota Nation Forum : Toyota Car and Truck Forums

It's SUPER EASY, and not that messy. Biggest chance for a mess is taking your short hose off the return inlet on the reservoir. Just keep a finger ready to stop it off when you take the hose off.

The ID of the hose is in fact 3/8" so just like the Toyota Nation thread use:
3/8 - 3/8" barbed hose coupling
3/8" barb w/ 1/4" male pipe thread
1/4" female pipe thread
teflon tape
1/2" OD x 3/8" ID vinyl tubing. A short piece to plug the return inlet, the long one to mate to the return line and go to your catch container

- Used a bottle pump to get out the old fluid from the reservoir.
- Jacked up front end to turn wheel and pump out more old fluid (didn't get much)
- hook up hoses and fill reservoir with new fluid.
- turn wheel back and forth to flush fluid with the pump. Keep the reservoir topped up. Watch until fresh fluid is running into your catch container.
- button everything back up and get the reservoir level back to the correct range
- I turned the wheel from lock to lock a few time to ensure any air is out. I turned on the truck to listen for bad noises from the PS pump. All good.
- put some fluid in the truck in case you need to top off or something afetr you drive a little

See the toyota Nation thread for more pics. Here's a shot of my set up.

The bottle pump is better than a turkey baster because the hole in the top of the reservoir is small. Or rather, it was too small for the baster I have.

BTW, I was at a Starbucks and asked if they had an old, empty flavor bottle ready for the trash (to get the pump for this), and they just gave me a new pump still in the wrapper. The girl behind the counter said they had tons. Another case of "you never know until you ask..."

Old thread, but wanted to say thanks! Mainly for the hose size, which is, in fact, 3/8. Well, in reality it is metric, but 3/8 works perfectly. I saw 7/32 in a couple of other threads and pretty happy I did more research to bump into this one. I was pretty sure that there is no way it is 7/32.

I changed the power steering fluid in my vehicle yesterday and it made a world of a difference.

A couple of things. First, I simply plugged the "dead" end with a dowel, which I made myself out of the stick I found I found. You can see it on the first photo attached. Second, I did not use any pump to get the old fluid out. I put some paper towels right under the connection of the hose to the reservoir and placed an empty Pepsi bottle (whatever the volume of the small one is) right after I disconnected the hose. Also, there is no need for the clamp because there is no pressure in the system and the fluid flow to the easiest route to escape, so it will not leak regardless of the presence of the clamp.

The fluid in my vehicle was of "diluted" fresh engine oil colour (see the first photo). Supposedly, it was changed at roughly 80,000 km. Today the Runner has just over 205,000 km. I still can't believe the results, to be honest.

The second photo shows that there was no mess, really. I have not cleaned up anything and that's what it looked like after the change. The only "spilled" fluid was on the hose itself as can be seen on the photo. The third photo shows the paper towels that were under the hose when I disconnected it. So really, not much of a mess at all.

Thanks again for the post!
