Chevrolet Corvette C7 2015 Automatic Gasoline mileage: 29 KM Brothers, a question My AC is leaking refrigerant I refill it every two weeks.. What could be the cause of the leak? Could it be the AC evaporator? And if it is the evaporator, where can I find it or order it from abroad, and if possible, the part number? And the second question Is the AC evaporator the same as the heater core? Thank you and I appreciate it
