Overheating and no heat. I had thermostat changed by a back yard mechanic. It has been randomly leaking antifreeze, but only when parked. What could be wrong?

Based on the loss of coolant, the first thing is to check for a leaking cylinder head gasket. Your mechanic can perform a chemical test at the radiator for that. It involves drawing air from the radiator, while the engine is running, through a glass cylinder with two chambers partially-filled with a special dark blue liquid. If combustion gases are present, the liquid will turn bright yellow.
