My 1986 s10 blazer 4x4 has a water leak.
The water comes out steadily like
almost as soon as I put it in the
radiator but it is leaking behind the
first belt pulley
Water pump or there is a small hose for the pump to the heater core
Agree with 83camino,unless you have and intake leak.
Water pump, either radiator hose, heater hose, if the intake was leaking that bad your motor probably has more coolant in it than has hit the ground. The old intakes were pretty solid. Could be a freeze plug. put your hose on the radiator and start looking for where the water comes out
