I was taking out my radiator to replace it and a tab got caught on the fins of the condensing unit. The damage is evident but I do not know if their is a leak/hole. I do not want to reinstall the radiator and all the parts, run the car, and see if there is a leak. Is there any way I can test for a leak with the car off? Is the condenser under pressure when the car is not running? Would I hear something? I am afraid that even if it is not leaking now, that the increase in pressure when the car is running will make it start to leak. Any help would be appreciated!
