My Tahoe is leaking coolant almost as quickly as I am putting it in. Is it most likely the intake manifold gasket?

Can't say for sure over the net!....Got to be able to locate that much of a leak!!! .. Have a car savvy friend take a look!.. NOT 'most' likely the intake! 'Possible' heater hose connection if at rear of engine... IF at front, possible water pump... Just got to SEE it!!!
