This is what happens when the heater tubes just exist… shut off valves closed and heater core empty…
those pipes will be retired!! New stainless steel pipes will join the radiator pipes under the car, coupled front and back to stainless, braided Teflon lined hoses! no more heated center console !
working on the heater-A/C core… the original A/C had flared fittings… I am changing to O-rings! New hoses as I found one hose was spliced with a tube and 2 hose clamps! No more Mickey Mouse 💩!!!
