When a coolant hose fails it is usually a good indicator of the condition of all coolant hoses, so there is a good possibility he will have to replace more than one hose.. also original hose clamps need to be replaced with new ones when replacing hoses.

Everything you are saying has already been looked at and tried without success. Any limp home ideas to make 500 miles
Expert:  Cardoctor71 replied 10 months ago.

I do not recommend driving this vehicle until coolant leaks are located and repaired , it is not worth destroying your engine , make other arrangements to travel 500 miles.
