My power steering pump in my 05 Explorer 4.6L V8 is starting to howl it's displeasure on a cold start at near zero temperature.
It doesn't do it when warm.
I thought I would change the fluid but the owners manual says to use Mercon ATF, but Ford now sells Mercon V as power steering fluid. It also warns not to mix the two kinds.
So, which one should I use?
And, which way to change it, siphon pump the reservoir and replace with new a few times, or let the pump pump it out and replace as it goes?
