Major confusion!?!? I keep loosing about two cups of coolant a day (50 to 60 miles) and can't figure out where it's going. There was coolant under the expansion tank so I changed that, new cap and related hoses. Still loosing coolant. Found coolant on bottom right hand corner of radiator so put a new one in. No change. Carpet is dry inside by heater core. Broke down and bought a universal adapter to do a pressure test; not loosing pressure. Also did a block test. HELP!!!!!
