2003 Jaguar X-Type coolant leak

Coolant is leaking from the under-carriage of the car. There is pools in the morning. It seems to quit dripping an hour after the engine is shut off. It does not over heat on drives either. What would tell me if it is the radiator or a hose malfunctioning? And there is also an odor of coolant burning. Could it be the head gasket, and what would be a sign of that? Lost job and can not afford dealers prices. Thank you very much.
