I have two questions: Where does one check the level of the power steering fluid on this car? I have both a Haynes manual and the 2-volume 1997 Buick LeSabre shop manual. Neither one shows where the reservoir is located and how to add or check fluid. The Haynes manual shows an earlier model engine that is different than my 3.8 liter V6.
Secondly, I get a grinding or rubbing noise when I make a fairly hard turn to the left. After I'm going straight, the noise is gone. It only does it on left turns. Any ideas?
