just follow what owners manual says

 

 

It takes ATF+4. Same fluid as the transmission.

How much SP fluid did you use? Just a top off or have you worked on it?
I don't know if the system is heavily dependent on the +4 or if they say that just to keep things simple with the fluids.

 

ATF+4 fluid. It was changed to that since the 3rd generation vans started having some issues with shudder, so there was a TSB issued to change it to ATF+4 back then. In the 4th gen, they just opted to use it right off the bat to head off any issues. It has excellent anti-shear properties which was why they switched to it.

When I first got our 3rd gen van back in 2009 and had to replace the power steering pump, I immediately cleaned out the remote reservoir and switched it over to ATF+4. Never had any issues in the 50,000 miles we've driven it since, and I refilled it with that when I replaced the steering rack and lines with junkyard replacements (due to heavy corrosion/rusted through line). Even the replacement steering rack I got had ATF+4 in it!

 

Well I guess I know what I'm doing this weekend!

 

I like to do the turkey baster method (with ATF+4).

 

What, you don't want to raise the van,crawl under it, take the hose off the rack and let it spray everywhere, even on you!

 

After many a power steering fluid flush with a darn mighty vac brake bleeder (would have to empty the bleeder 2.5 times for one reservoir emptying 😑) I made this nifty little setup, makes my life SOOO much easier.

Ain't pretty, but it will empty the PS reservoir in about 3 seconds!

 

Ah ha, so this is how one makes FAKE moonshine.
