The owner’s manual for my 99 V70 says to use ATF in the power steering. But, it does not have ATF in it now. The fluid in it looks like it was probably clear when new, and is now kind of a dark clear.

Any idea what it would be? I have seen clear steering fluid, but I am thinking there is more than one type. I don’t think my car is new enough to use the very fussy fluid that is maybe something like Pentoison (?? or I think it was something like that unless I am mixing up my machinery).

I thought I would try to change it out when I replace the serp belt, but don’t know what to replace it with. I am thinking that throwing ATF in now might not be a good idea since it is used to what it has now.

Thanks,
Charley
