freeze plugs

Hey guys just had a question for ya... I have been running water for coolant instead of antifreeze and didn't change it in time before it got 20 degrees one night. So I went to move it in the garage the next morning and all the water drained out.

So my guess was that it popped a drain plug. Only thing is I know nothing about this truck and was just wondering if anybody knows where the freeze plugs are at and if they are super hard to get to. I took a quick look in there but didn't see anything.

This is a 1988 mighty max with a 2.0 manual. Thanks.

They're probably under the intake and exhaust manifolds. They're not drain plugs, they're the holes that were left after casting the block. Never a good thing to pop them. Good luck.
