I wanted to see if anyone else is running atf for p/s fluid. I replaced the pump last sunday due to a leak with a reman and now i have a slight leak from my pump. The truck had atf in it when i purchased it and i didn't feel like flushing the whole system. Just wanted to see if its me being lazy and i should have flushed it and replaced the fluid with p/s fluid or i just got a bad pump.

 

Do not ever use p/s fluid in a Toyota!

​Dexron iii atf is the only fluid you should have in the power steering system.

It must be a Japanese thing, I have a Suzuki and Subaru that spec dexron iii as well.

 

Ford/Mazda cars of the 80's and '90s, maybe longer, specd the old type F ATF for their power steering, even when the trannys in those cars specd Dextron/Mercon III

Type F has less friction modifiers than Dextron. More of a true hydraulic oil.

Toyotas do like Dextron III.

I have used type F without trouble as well. No 'power steering fluid', for sure.

 

That is what i thought, i just wanted to confirm so thank you. Just came in from the garage and found it leaking from the flow control valve....

New pump is on the way.

 

My 2002 Montero also calls for dexron III

 

Mitsubishi, and Mazda got added to the list: it's official, using atf as power steering fluid is a Japan thing.

 

Gee whiz, all you gotta do is read:

 

So few seem able to read today unless it is on there phone!!!

 

Though to be fair, the older reservoirs got a decal with the specs. By the time it was in my hands, mine was wordless. I think I found that info in the owner's manual.
