Coolant in, coolant out

Yesterday the Discovery started getting very hot and getting down on power (felt like the turbo wouldn't spool up, couldn't get up a hill after a while and had to stop to let it cool) until I let it cool down and then it would drive like normal again for a while. I found an inter cooler hose was split (entering the inter cooler from turbo side) which I will be replacing tomorrow and I believe this was the main source of the issues yesterday (air not properly getting properly cooled and throwing hot air into the engine, making it not run properly and read very hot?).

However, this morning I went to check the coolant - empty reservoir. Topped it up, and everything I poured in came out the bottom .

I haven't had a proper look yet but would welcome some ideas as to what could have gone wrong based on yesterday's symptoms. I'm hoping a coolant hose has just come undone or split with the added pressure, but I'm guessing I could be looking at something more serious like a thermometer or gasket? For reference, the coolant was pouring into the ground just behind the diff, though obviously that doesn't mean that much, could have run there from nearly anywhere.

Thoughts?

Ok, as an update, I have found the water pouring like Niagara Falls out of what looks like a round brass plug the size of a milk bottle cap located behind the engine mount on the drivers side of the car. I believe it's a core plug?

Are these threaded or can they be tapped back into place? I hate to think I need to remove the engine to get it back into place!

They are tapped in, using a suitable size socket, Sod's law it isn't easy !

You're not kidding... Looks like i might need to take the engine mount out to get to it properly!?

no need to drop the engine mount
just remove the starting motor

I can see the one you're talking about, but I've had a look and there's definitely no way of getting to the one I have leaking without dropping the mount. I just hope I don't go through all the pain and find a cracked block instead
