Brand New Water pump, intake manifold, thermostat, fuel injectors, spark plugs, radiator, radiator hose, radiator cap, intake gasket, and coolant. Currently coolant is drained, but whenever I drive my car within a few hours, all my coolant is gone. My engine overheats and spews coolant from the radiator cap at boiling temps.

I'm thinking I may have a blown head gasket, car runs fine, just a stupid overheating issue. Anyone have any experience with this issue?
