I posted up about the Fluidyne rad I picked up cheap a week ago. Well I really bought it based on the size only, and had a buddy that lived close pick it up for me. Well neither of us noticed for days, that it doesn't have the fitting for the heater core. Living in Canada, running without heat is not an option. Can I just plumb the heater core from the pump and or manifold? Are there fittings made for this application? Any ideas? Or am I reselling this thing?
