works as advertised
Dye is highly visible and I was able to rapidly pinpoint the leak in my AC system. Worked like a champ. I am highly pleased. Please remember that you should not cross contaminate different coolant types. This one is for R-1234yf

It’s so easy to use
We fitted a new ac pipe to the car and got it recharged by a garage and it only lasted three days. So we bought and used the ac leak stop, then refilled the system and it’s been working ever since. It’s so easy to use.

Actually worked
I was pretty skeptical but after $3000 in repairs and trips to fours different mechanics (two dealers and two independents) this little can fixed my air leak. My 1234xy would last 2-3 weeks before. Now it is going on 9 weeks and is still going. Worth it and bought another.

Worked perfectly for me
Use this on my wife's van. Has a very good UV die and easy to use. I cannot however tell you how easy it is to find the leak since this appears to have sealed it. Haven't had to recharge all summer. I was having to recharge it once a month last year.
