Foamy Power Steering Fluid — and Groaning Sound — 2001 V70 T5

If you use the turkey baster as a previous member suggested, you will be able to tell the color of the fluid…If it is red, it is ATF and is the wrong fluid…Pentosin is green…Foamy fluid has air bubbles mixed in and will make noise due to cavitation…The air does not get mixed into the fluid due to an air leak somewhere,it gets introduced right in the reservoir when the returning fluid agitates and swirls the reservoir, whipping it into a foam…Pentosin has additives to prevent that…
