There is usually one on the bottom of the radiator.Possible AnswerI have gone to the dealer and the chief mechanic said that there is no drain plug on the 1997 Mazda protege. Sounds sketchy to me, but I can't find it either. ***Many (most I think) cars have two drains in the cooling system -- one on the bottom of the radiator and one on the engine block. You normally open both when changing the coolant because the coolant won't drain out of the block very well if you don't. I expect that the dealer and chief mechanic were answering the question "Where is engine block coolant drain plug?" I have just been crawling around under my 2002 Protege which I think has much the same engine as the 1997. Damned if I can find a drain plug on the block. Based on what you were told, I'm going to proceed on the assumption that there isn't one*** vtcodger
