Re: What PSI range for a water Press. gauge for my Force??
How did you get the plug out?
Mine came out relatively easy. Tapped it a few times with a 10-oz. ball peen hammer, then used a big ol' flat-bladed screwdriver with a 10" wrench for leverage. My plug was made of stainless steel, and of course the engine block is aluminum, so if your's is the same it would not be surprising that the two metals have corroded together.
I'm no expert, so take the following advice for what it's worth, but if your plug is really stuck, I would go with some judicious application of heat to the general area. Assuming you would use a propane torch like I would, don't apply enough heat to burn the paint, but it should be hot enough to feel fairly uncomfortable to the bare hand. Then, hold an ice-cube onto the top of the plug (but not the surrounding area). Give it a 10-count and then try to undo the plug. The theory being that since stainless steel has a lower coefficient of expansion than aluminum, the iced plug should not expand as fast as the aluminum and therefore the threads will loosen up and you might be able to break the corrosion free. Or something like that.
