I replaced the heater core successfully with only heat coming out now instead of coolant and steam/smoke. Now I have noticed my A/C isn't making the air cold. I refilled the refrigerant and it became cold for a little while. About a week after I turned on the air and it was not cold. I did not mess with the A/C at all throughout the heater core replacement. There was a part to the right of the heater core that had the same radiator style. I believe it was the AC evaporator and I know I played with that a little. (Rookie mistake for the actual heater core) I think it may be a leak since it stayed cold for a few days. If anyone could answer this for me, please don't be hesitant. Tired of sweating!
