First? Hey, all. Been hearing a whine from PS pump on the 99 Ford Expedition. Will be wanting to look at Power Steering fluid next.
A couple of quick, possibly dumb questions, so that I may make the right move:
1. Shall I get a spray bottle, and remove the old PS fluid from the reservior?
2. Is there a best PS fluid for Ford, or will the Supertech or the Prestone (are both fine? I would choose ST) work well?
3. Will this eliminate the whine, and ever so slight heavy feeling?
The fluid may be low.. my question is as to changing it, and not just topping it off.
I feel as though I am giving this truck its pre-160,000 mile service.. perhaps to repeat in another 4k. It runs real smooth.
Beyond this, only other issues are: 1. Sunroof not 100% closed, as evidenced by the car wash
and 2. Headlight switch does high beams, not low beams. So high beams are always on, when lights are on.
Thank you.
