A/C leak S70

Use a valve tool to tighten the schrader valve, if it might be loose. Most cans of r134a contain dyes (yellow) which can be seen with UV light.
NAPA sells a 3oz can of leak stopper which must be chased by a can of r134a. It will stop most leaks. Just remember, AC shops refuse to evacuate any system with leak stopper in it, because it destroys their equipment. AND, if the leak persists you will not only need a new evaporator, but a new drier, hoses, condenser, etc. So says my local AC shop.
I just keep adding r134a at $11/can.
