Volvo: power steering fluid or ATF?

First off, don’t pay any attention to internet forum posts when replacing or topping up fluids. ALWAYS follow the manufacturers recommendations.

All you have to do is read that owners manual and it will tell you exactly what to use and how much.

If you do not have this book, phone or go to your nearest dealer and ASK what is supposed to be used.
Supply information needed: the year/make/model/engine size and whether automatic or standard trans.
