No, it's really a remnant from the block casting process, but also does provide some protection if you don't have antifreeze and the coolant freezes. These are steel or brass plugs & replacement is routine, but can be messy because of access. I think there are 4 altogether. > > What is its function? See above. > > Can I get one fairly easy? Yes, and there should be an "emergency" sort of plug made partly from rubber, with a bolt to tighten. Best is to have all replaced - if you do it yourself, check the archives for how to use this opportunity to clean up your coolant system also. > > What should I do to the engine before I start it up again (like say nice > things to it?) when the hole is finally plugged (it had to go about a mile > with no coolant before I could pull over)? Probably no problems - doesn't seem far enough to cause overheating. > > Will Laura Bush ever find a decent cocktail in the White House? Doesn't Dubya have a secret stash? >
