Anybody got a pic of where the drain plug is for the block?
Want to drain the engine of as much coolant as possible. Which bolt needs to be taken out of the block in order to perform this? Anybody got a pic of the location?
Thanks.

What motor? ASSuming your username then I would say a 22r. It is located under the exhaust manifold on the the side of the block roughly under number 3 cylinder. A 14mm socket is what you need. This is the block drain plug.

I think I"m on the right bolt, and have sprayed it with WD-40, but it's in there pretty good. Kinda scared of putting too much grief on the bolt, in fears of breaking it off.
The reason I want to get the bolt out is to drain the system down and change the cam out, since the cam is bad. Hoping I can change the camshaft without breaking the head gasket loose.

Any suggestions on getting the bolt out? I've sprayed it with WD-40, but it's still in there good. Should I start the engine, let it warm up, and then give it a try?
Just hate to snap the dang thing off.

it is from my experience that heat wont do much to the bolt, since heat causes things to expand. in auto class i had a problem with a car getting a bolt off, he suggested i leave it outside for about 30 minutes to let it get fairly cold and let it contract, then it took mild pressure to get it off. if its cold where you live right now, try that, or you can find some sort of canned air and just spray it with that

get yourself a 14mm 6 point wrench, and smack it with a hammer. usually that thing hasn't been removed in years, and it can be a PITA the first time taking it out. some of them have a 2 piece plug, one part screws into the block and it has a brass screw in the end.

You ever heard of endust?
I think he means this junk. You know the cans of compressed air that you used to grab and flip over and shoot the cold ass fog all over people? Keyboard dusters, electronic duster crap. The compressed air is propelled out by a little amount of CO2 (I think), which is cold, so if you flip the can over and shoot it, you can freeze stuff, like food, bolts, people's fingers, you know? Get creative, or something.
PB blaster is also God's greatest gift to mechanics, modders, and 'yota wrenchers everywhere, and it's cheap, too.

I don't know if that would get the antifreeze away from the head gasket or not by just draining from the radiator. I don't have time this year (very slow at getting work done to the 4runner due to my "honey do" list ) to pull the head, so hoping i can just swap the cam without comprimising the head gasket.
