Does R134a have UV dye?
Because Freon™ 134a UV is essentially pure Freon™ 134a with a small amount of UV dye, you can expect the same AC cooling performance as you would with pure 134a. The pressure-temperature relationship is the same; refer to the chart at the end of this bulletin. via

What happens when Freons are exposed to UV light?
The presence of Group 17 elements such as fluorine, chlorine, and other such elements contributes to their stability. The molecule is extremely stable due to the presence of C-F and C-H bonds. However, in the presence of ultraviolet rays in the stratosphere, freons die out due to UV ray exposure. via

How is a dye solution added to the AC system for leak detection?
It’s a method in which a small amount of fluorescent dye is injected into and circulated through an operating system. The dye/refrigerant mixture will escape and accumulate at all leak sites. By then scanning the system with a leak detection lamp, all leaks will fluoresce green or yellow, making them easy to spot. via

Does Stop leak work for car AC?
Does home AC leak sealers work? Most AC stop leak sealers work well to stop small pinhole leaks in the AC pipes, but it’s not recommended by us. It is not proven that they can stop leaks around O-rings or shaft seals, which is much more common than pinhole leaks in AC systems. via
How long does Freon last in a car with a leak?
You’re safe to drive without checking the Freon for at least five years—or until you notice a problem (like no cool air). If you need Freon more frequently— like if you’re not able to cool down your vehicle even if the refrigerant was recently topped up—then you may have a leak. via

How do you test for Freon poisoning?
There are no medical tests available to diagnose Freon exposure. There are also no FDA-approved drugs to treat the poisoning. In the case of inhalant misuse, the affected individual may need to be hospitalized in a drug treatment center. via
Is Freon an anesthetic?
Freon, a new and safe refrigerant anesthetic for surgical skin planing. via
How long does it take for UV dye to work?
Depending on the size of your system, it can take anywhere from 5-45 mins. via
What color is AC leak dye?
The fluorescent leak detection requires the addition of a fluorescent dye into the refrigeration system. This is done for the dye to mix with the lubricant to circulate throughout the air conditioner. If there is a leak, dye will come out with a bright yellow-green color to help you pinpoint where the leak is located. via
How do I fix my AC leak in my car? (video)
Can you dye your coolant?
Any trace colourant in the water / coolant of an engine coolant system will usually suffice. I have previously used a food colourant liquid as a dye and it has worked well. via
