I've got my '94BRG up on stands, doing oil/filter, and thought I should drain/flush the cooling system since I don't know when/if the previous owner did. My Haynes manual shows a picture of the engine block drain plug... but I sure can't find it on my Miata... perhaps the picture is of a 1.6 engine, or maybe Haynes screwed up and inserted a picture from a different auto. Can anyone advise exactly where the engine block coolant drain plug is, and/or point me to an on-line resource that will show me?
thanks,
Pete
