For those motors that use drain plugs in the block /manifolds may sure you probe the opening with a nail,screw, drill bit, wire, etc. TO MAKE SURE IT DRAINS. just removing the plug and seeing nothing come out DOES NOT mean it dosent contain water that could freeze.

Very very good tip. Sand or crude can build up in there and block the hole, as it catches on the plug. I've had to use a nail, just like you suggest, to probe through it and once through I always have a little bit of water come out.
This tip could save your engine. Good one BtDoctur!!!!
