If the engine block is cracked, it's best to install another engine, however it can be fixed but not recommended. It may be the freeze plug that needs to be replaced. And again it could be the line running from the transmission to the the front at the radiator with a hole or crack. I would try to fill with water and crawl under there before the engine gets hot to see where the leak may be coming from. Then look from the top of the engine. Good Luck
If the engine block is cracked, there no fix but replacement, check and make sure it's not the rear freeze plug, the rear freeze plug is between the engine block and the transmission.
Remove head and have head and block checked for warpage, re-install with new gasket and sealer
Cracked block? Eh... You can try to have it welded but thats not a promising fix. I think you may have signed your jeeps death certificate. On the bright side you can pick up a used motor from a salvage for around $450. Try welding it. Its worked for me before.
