I am getting steam and coolant from way down under the block near the drivers side fire wall. It has to be leaking and have a breach in the coolant system/ up -down /in this location. It is Under the booom and near the drivers side fire wall. What connects to the coolant system here? Heater core? A simple hose fitting? I need to jack this car up high and look at where it's coming out from. Simple ad that.
