I have a 01 Bonneville SE. My father has replace my front motor mount and now we are wondering about where the oil pan is located. My oil leaks and we are going to try and replace the gasket to see if that fixes it. I have an idea about which one it is but HE thinks it has something to do with the transmission???? I have never had to fill up my transmission fluid. Oil and power steering fluid is the only things that leak. PLEASE HELP ME. Point me to some pictures or maybe post some so I can show him.
Look at the rubber boots on the ends of the steering rack. See image (original C/O Danthurs, I think). If they appear wet, I'm told that the rack must be replaced. I saw this on my Lesabre, so I figured I had nothing to lose so I added a bottle of power steering conditioner that conditions internal seals. So far it has worked and solved the leak.
Best thing to find out what your leaking is clean the floor real good. Then lay down some white cardboard or paper towels. Then look in the morning. Make a note of where the spots are, how big they are, and what color they are. Red, transmission fluid, brown, oil, clear, steering fluid, pink/orange/green, radiator fluid depending on the brand you have.
You guys are awesome. I will be trying all this and more. My Bonneville is paid for but it has so many problems. I want to fix all the mechanical problems then maybe make it look better cosmetically. All the guys on here make it easier on me.
Start with general maintenance, fluids, plugs, etc. then pick something to fix and work on that. when done, move on to the next. don't look at all of it at once. It'* one issue, then another, not a whole bunch of things.
