<small-six block coolant drain plug>

Someone asked about draining the coolant in his 2.0 baby six, saying 
there was no drain for the block...
    I have just run out into my garage in my skivvies to confirm for 
all of you:

            There is!!!

    It is on the exhaust side, by the #5 cylinder, a 17mm or 19mm hex 
head bolt.  Its location is similar to the big 6 and 4-cylinder blocks. 
It is the rearward part of the block to allow complete drainage of the 
cooling jacket.  Look again: it is behind a "ridge" in the block that 
is an oil drain for the cylinder head.  The plug is just below the 
level of the freeze plugs.

Enjoy,
