A hole in your block comes from massive mechanical failure. Mostly a broke rod or crank. If you have a hole in your block, you need a new motor.
A hole in the engine block is God's way of telling you to get a different car. You get a hole in the engine block when a piece of your engine--normally a rod cap--comes off at full speed and goes through the side of the block. And there's no way to fix it.
it is not a cracked engine block it is just a loose block
This is the diameter of the cylinder hole in the engine block for the pistons.
The spring end faces towards the engine block and if the thermostat has a vent hole the hole is at the top of the thermostat

Maybe the coil pack don't know what hole you are talking about
That is the water pump weep hole. The water pump has failed.
The spring faces the engine block ( and the vent hole goes to the top )
Turn them so the hole lines up with the holes in the block.
An oil leak.
A hole in the radiator would do that, or a damaged radiator cap. It could be a cracked engine block that is allowing cylinder pressure into the cooling system, pressurizing the water until it breaks through a weak spot in the radiator.
Lack of anti-freeze in sub-freezing temperatures. The water in the block freezes and expands.
