How to Use

1. Add the UV dye through the low-pressure filling port of your A/C system, just as you would add refrigerant oil.
2. Turn on the air conditioner switch (for dual-zone vehicles, activate both front and rear A/C).
3. Allow the A/C system to run for at least 10 minutes so the dye circulates throughout all refrigerant lines.
4. Put on your protective UV glasses and scan all hoses, fittings, connectors, and components with a UV flashlight.
5. Any area showing a bright fluorescent glow indicates a leak — repair or replace that component as needed.

Frequently Asked Questions

Q: Is this UV dye compatible with my car's A/C refrigerant type?

A: Yes — this eco-friendly fluorescent UV dye is designed to be universally compatible with most automotive A/C refrigerant systems, including R134a. It mixes safely with standard compressor oils and will not damage your system's seals or components.

Q: Do I need a special UV flashlight to see the leak?

A: You will need a UV (black-light) flashlight or a dedicated A/C leak detection UV lamp to see the fluorescent glow. The dye glows brightly under UV light, making even tiny leaks easy to spot. UV protective glasses are also recommended for eye protection during inspection.

Q: How long does the UV dye stay in the system?

A: The fluorescent dye remains active in your A/C system indefinitely, which means you can re-check for new or recurring leaks at any time by simply scanning with your UV flashlight — no need to add more dye for future inspections.

Q: Can this product be used for systems other than air conditioning?

A: Absolutely. This versatile leak detection dye can also be used to identify leaks in power steering systems, fuel lines, automatic transmission fluid circuits, engine coolant systems, and hydraulic systems — making it a truly multi-purpose diagnostic tool for any vehicle.
