Our reference material has nothing on a drain on the engine block to drain it from coolant. Usually there is a screw out/in petcock located on the bottom of the radiator on one side or the other that allows you to drain the coolant from the system. If your vehicle's radiator is not supplied with a petcock like this, then you can remove the lower radiator hose from the radiator and drain the cooling system that way. If you are still concerned about the coolant in the engine block you could displace it with compressed air pumped into the system through the above said lower radiator hose into the engine block that way. Please get back to us with how everything turns out. I hope this helps.
