Just did this job + all new hoses and clamps.

I went through this thread pretty thoroughly, so if this has been covered feel free to roast me.

I found a cheaper alternative to getting a replacement reservoir for these trucks if you aren't in need of the metal bracket. I can thank an old Motorweek review segment of the 2006 Pontiac GTO for this. This reservoir is used in many vehicles so after seeing it under the hood of that GTO I dug up a P/N.

GM 92202130

I received the part yesterday and can confirm it's identical to the reservoir in our trucks. They changed the labelling on the cap to just a couple info graphics, but that's irrelevant to me.

Wow! You have telepathy powers!
We had a GTO at work for sale until a few days ago, and since it drained it’s battery while seating , we had to jump start it all the time.

I saw the reservoir and googled it to check it out, even tried to find similarities between them, and was about to post here to ask if someone tried one. Just got busy, the GTO sold and I completely forgot about it.

Thanks for the reminder!

Rhetoric - thank you for providing the part number for the GM power steering reservoir. I just swapped a new reservoir in this evening after flushing my steering system with 3 quarts of new ATF. The reservoir costs $38.79 on Rock Auto, with 7.99 for priority shipping. Total cost of the fluid was less than $20.00, so overall a very economical way of replacing the old/stock power steering reservoir. (Mine was an ugly yellow color after 24 years of life on the 2000 100 Series.)

Did mine this week!
I simply unplugged the lower hose.
Filled it with 400ml to max cold.
Drove it for a week.
Drained & filled 400ml again today.
Fluid from Toyota dealer, $10.

I used to think the steering was heavy because of the 35s, but now it is much better!

Even though i noticed the difference in steering feel after changing the fluid with Mobil ATF, I found a bottle of Redline D4 for $10 on facebook and decided to do another exchange

Glad I did!
The difference is huge! Steering is much lighter!

I overfilled it but didn't notice the fluid expands when hot, I guess because it is synthetic and the extra fluid helps with keeping it cool

Best to not overfill.

Watch level during first step of bleed (engine off, tires off ground) level drops and raises. Too much fluid and it find a way out of reservoir (cap and or hoses)

BTW: Mobil (not all are full synthetic) is not the same as Mobil 1 (all are full synthetic).

Has anyone installed a filter for the power steering system?

 

[2001LC]

If I was going to install PS inline filter. I would use a PS inline filter. They have almost no flow restriction and powerful magnets.

Amazon.com

above link, is to a good one of the magnefine line. Magnefine has even better and cartridge type.

Did it with Redline D4 this time, I felt a different steering immediately! Nice! Thanks for the tip @Tareq !

 

[fussychicken]

Man, what a great little project! And what a nice improvement!

This is also yet another reason to love these forums due to the great finds by @Rhetoric for the reservoir and @Tareq for the Redline D4 tip. Thanks guys!

Oh yeah, and also thanks to @shtbrwn86 who found the return hose with Breeze auto. I didn’t feel like driving all around town trying to find the right hose at an auto parts store so I just ordered from Breeze and the hose works great. It was a little tight getting it onto the new reservoir, but it wasn’t bad getting it onto the hard lines down by the rack. (More here if you want to order from Breeze)

I’m not sure how much improvement came from the redline D4 itself, but there is for sure a small but noticeable difference in lighter steering effort after doing this change! I ended up flushing through ~3 quarts before calling it good. So glad to have some good synthetic in there knowing how much heat this fluid deals with.

I also don't know if my rack has ever been replaced or not. The boots are still dry, so fingers crossed this fluid change will help it last a little longer.

My parts list for my 2001:

New Reservoir	GM GENUINE 92202130	Rock Auto
Return Line (2003+ is different)	3/8" ID Conti Hose	Breeze Auto
Feed Line	44348-60240	OEM Toyota
PS Fluid (ATF Fluid)	Redline D4 ATF	Amazon
Seal Reviver	AT-205	Amazon
Feed Line Clips	90467-21010	OEM Toyota
Return Line Clips	90080-46355	OEM Toyota

My final photo looks almost exactly like @Rhetoric lol

Who knows if or when this has ever been done on this truck. The fluid was absolutely black with clearly some not so great looking sediment in there.

glad I stumbled on this thread...I just rolled over 265k miles and pretty sure this has never been done...love this forum!

Will the OEM Toyota cap fit on these GM reservoirs? I like to keep things looking as stock as possible and my cap is still in good condition.

Yes they will. That is exactly what I did. You can even pull the gasket off the new one and put it on the OEM cap.
