Here is the scoop, I replaced my intake and head gaskets due to the fact they blew and it cost me 2 grand, my car is now overheating and losing water? Do you think it could possibly be the water pump? How do I check and see? If not any other suggestions?

Thanks.

Do you have an actual leakage if not then its being burn in the combustion chamber.

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following:, Pressure test the Rad. Cap, Clogged radiator, air lock in the cooling system, Fan clutch, Radiator electrical fan, collaspe hoses, water pump.
