So I decided to take some time today and change the fluid in my Power Steering. Ever since it got cold I've had a moaning PS pump and have been trying to figure out how to fix it. It's always been fine on fluid level, but when I checked it the other day right after coming to a stop it was very frothy. So I decided on the fluid swap. I decided on a Synthetic Power Steering Fluid and read the FSM for proceedure. Seemed pretty straight forward, but now even the new stuff is frothy right at engine start-up. I have to admit that it was pretty tough doing it by myself and keeping the reservoir full all the time. Did I introduce air into the system during the process or is it supposed to be somewhat frothy at engine start? (Somehow I doubt it.. :-\) Good news is he moan is significantly less than before. Plus, anyone have a better method of swapping out the fluid? I have a hunch that I'm going to have to do it again. Thanks.
