      Can you tell what the difference is between Type M and Type F ?

        Type M fluid is for a CVT transmission. It probably has very different properties from Type F which is for traditional automatic transmissions. It might be ok to use but I would not use it.

          I've heard you can use ATF as steering fluid, but then again a bottle of steering fluid is like $2

            The problem is that I live 200 miles into the desert in Saudi. I need to go into town to get the power steering fluid. That's why I want to know if its OK to top up with ATF for the long drive.

              I'd say don't put anything in it other than type F (NOT type M, designed for very different conditions) transmission fluid. I'd rather run low for 200 miles than have to replace or flush everything somehow because you put the wrong fluid in.

              Type F transmission fluid is the fluid recommended for these cars by Ford.

                Top it up with what you have, and when you get the correct stuff, just use a turkey baster to pull out as much as you can and swap it. The power steering system is not grossly picky about what it uses. If you use too thin of a fluid, it makes more noise. The additive properties and all that are completely unimportant. Its better to top up with a different kind of fluid than it is to run it low. Air is an absolutely horrible lubricant, and running the system low enough to churn and suck air will ruin the pump.

                and yes, the factory-specified fluid is Type F. Many people run Mercon/Dexron III without any problems, though it does make more noise when you do this. Power steering fluid has similar problems with noise. Its just not that critical.

                    Ok, I tried to find it but I couldn't find it. How do you flush the power steering system again. I topped it off with power steering fluid and shes whining...annoying....

                    I was told you pull the return hose (no clue where it is at) and run it into a bucket. Turn car on and pour in atf while someone turns wheels to replenish. Am I right?

                      Nah, suck some out with a turkey baster, fill it up with new stuff, turn the wheels back and forth, rinse and repeat. A little whining isn't out of the ordinary on these.

                        I've successfully used/use Dexron in mine. I wasn't going to buy a bottle of Type F just for power steering when I have gallons of Dexron III around.

                            As long as you dont use motor oil, you're fine. Hydraulic systems are hydraulic systems. I run tractor hydraulic fluid in the auto transmissions on my 96 saturn and 94 s blazer. Converter stalls at a lower rpm tho. 15k on the chevy, 80k on the saturn with the real hydraulic fluid. No problems yet.

                            Motor oil is a different story though.. Don't do it.
