I don't see any engine coolant lines going to that water heater. That looks like an electric only, or the engine lines aren't hooked up.
The elbow is a compression style fitting. Is the crack on the water IN connection or the water OUT connection?
You would most likely get very little water if faucets are all closed. You would always open the hot side of the faucets and drain the tank to below the level of the fitting before disconnecting it.
