Where is the coolant drain plug on the ENGINE of 1984 Mazda b2000
I know my truck has a coolant drain plug on the block somewhere (in addition
to the drain plug for the radiator). Can anyone tell me where to find it? It should
be a 4-side bolt. I find some bolts here and there, but I'm a little reluctant just
to take 'em out to see what happens. Thanks.
