It might be high water pressure in system? When did you last check your radiator cap?

Cracked head pushing pressure into the cooling system?

It's difficult to say why it is leaking. If no or low antifreeze is in the system it will rust and cause a leak.
Take it to a radiator shop and ask for a free quote on repairs. They will tell you the fault.
To make out a head problem, cracked or blown gasket open the radiator cap when cold and start the vehicle, it will through water out the radiator while the engine is still cold.
