You can lose a large amount of coolant and not see any leaking onto the floor. There are several large web areas on top of the block that can hold coolant and then boil it. Most likely not only are the hoses behind the water pump leaking but also the "o" rings on the distribution pipe.You must replace all of the hoses on the engine, the gaskets, and "o" rings and should also replace the water pump.Be prepared to drill out bolts that you will break as you disassemble the top of the engine and distribution pipe. You cannot settle for anything less than a system that can hold #15 psi hot for over 15 min. Anything less means you still have a leak somewhere.You probably didn't blow a head gasket but the things to look for include, a white frothy oily film on the dipstick, two adjacent cylinders with a higher than normal compression pressure, a pressure cap that always seems to be letting out coolant with a need to constantly bleed the coolant system, excessive blowby in the crankcase, higher than normal operating temperature. Any or all of these symptoms would indicate a blown head gasket.
