Went to recharge my AC system on a 2000 Acura TL, the pressure gauge showed the pressure being on the line of "empty" and "filled", put some refrigerant in and the gauge didn't move at all put more in and it still didn't move. Eventually the entire can was emptied and the gauge was still in the same position.
Car ran for about a half hour, air was cold. All of a sudden the engine started smoking in what appeared to be a coolant leak near the AC compressor. Gauge now shows the pressure in the system at empty, and the AC compressor doesn't appear to kick on. But there's no more coolant leaking from the car.
Can anyone give me insight into what happened?
