1998 Jaguar Vanden Plas • V8 • 59,000 miles

I have a 1998 Jag XK8 with 59000 miles. I keep getting a error code of engine coolant level low. I refil the expansion tank and it will blow the tank empty after it worms up and the thermostat opens. The fans are working and I have replaced the water pump, thermostat and cap on the expansion tank. I noticed that the radiator hose attached to the thermostat housing calapising. Whats next? Is there a certin way to fill the radiator? I have no books that came with the car. Any help is welcome.
