1995 Yukon ran hot put water and coolant
started it back up it water consistently run
from the place inbetween the lower belt
pulley on the lower motor block what could
possibly be wrong since the lower hose has
only a little water coming from it but it's
actually pouring from that lower area by the
engine block could it be a seal broke Loose
or the theramost sticking or a freeze plug
Post of the pic, but from your description that sounds like it's leaking from the water pump. Don't drive it if it is overheating, or you risk blowing the motor. If it is the water pump it will need to be replaced, replace the thermostat at the same time since you have the coolant drained. Very doubtful it's a freeze plug, but if you take it to a shop, have them check their condition as well since you have an older car.
