PSF-3 is a Hyundai fluid specification that pre-dates Hyundai's acquisition of Kia from Ford. If you were pull out the lube chart printed in the owner's manual of any Hyundai vehicle manufactured during the mid-to-late 1990's, the power steering fluid would be listed as "ATF Dexron II, PSF-3 type fluid". The original PSF-3 product was Dexron II. True D-II is getting harder to come by, but Dexron III was formulated to be backward compatible with systems originally using Dexron II.

A little off topic, but I think Ford was merely one of the share holders of Kia, and Hyundai didn't actually buy Kia from Ford ?

Personally I'd stick with what Kia spec, and if unsure, play safe and buy it from them.

Important to find the leak !

 

i use good old power steering fluid valvoline maxlife with stop leak works great

 

See what I mean.....lots of confusion out there.

 

Straight answer is, USE what KIA calls for!! PSF3 is what you need to use,plain and simple!

 

they do not make psf3 anymore dealer does not recommend atf repeat no atf alternatives recommened high quality power steering fluid or new and improved just means more expensive PSF4 anyway my two cents

 

PSF3 is similar to generic power steering fluid. I have used it as well as dexIII to top off with in my own Kia vehicles. PSF4 is different and is only called for in a few specific vehicles. It is an extreme pressure fluid with a different viscosity than the other stuff, not compatible.

 

Well....what-da-ya know.....this stuff really does exist!
