Customer Questions & Answers

  • Question: What is Certified A/C Pro Car Air Conditioner Leak Detector Dye used for?

    Answer: Certified A/C Pro Car Air Conditioner Leak Detector Dye is specifically formulated to detect leaks in air conditioning systems of cars and radiators. When added to the A/C system, this UV dye circulates with the refrigerant and helps pinpoint any leaks by emitting a bright fluorescent glow under UV light. This visual indicator makes finding and fixing leaks more efficient, ultimately saving time and preventing further damage to your vehicle's cooling system.
  • Question: How do I use the A/C Pro leak detector dye?

    Answer: To use the A/C Pro leak detector dye, first ensure your vehicle's A/C system is turned off. Carefully add the dye to the A/C system through the service port using the included applicator or a compatible injector. Then, run the A/C system at maximum for approximately 10-15 minutes. Using a UV flashlight, inspect all connections and components; any leaks will be visible as a bright, glowing substance, easily identified against the standard automotive colors.
  • Question: Is the UV dye safe for my vehicle?

    Answer: Yes, Certified A/C Pro Car Air Conditioner Leak Detector Dye is designed with safety in mind. It is non-toxic and compatible with all types of automotive refrigerants and oils, making it safe for use across different vehicle systems. This leak detection solution helps prevent costly repairs by accurately identifying leaks without harming vehicle components, providing peace of mind for car owners.
  • Question: Can this product be used in both A/C systems and radiators?

    Answer: Absolutely! Certified A/C Pro Leak Detector Dye is versatile and can be used in both automotive A/C systems and radiators. This dual-purpose functionality means you can effectively assess the integrity of both systems using the same product, making it a practical choice for comprehensive vehicle maintenance and repairs, giving vehicle owners greater value from their purchase.
  • Question: How long does the dye last in the system?

    Answer: The dye remains in the system as long as the A/C refrigerant is present and functional. It can last for several months or even longer, depending on the system's condition and use. Periodic inspections with a UV light can help track down any new leaks that may develop over time, ensuring you stay ahead of potential problems within your vehicle’s A/C and cooling systems.
  • Question: Can I use this dye if my A/C system has already leaked refrigerant?

    Answer: Yes, you can still use the dye even if your A/C system has lost refrigerant. However, for the best results, it is recommended to recharge the system with the appropriate refrigerant before adding the dye. Doing so allows the dye to circulate properly and effectively highlight any leaks present. This proactive measure aids in identifying issues promptly, avoiding more severe damages or costly repairs down the line.
  • Question: What type of UV light should I use for detection?

    Answer: A UV flashlight or blacklight specifically designed for automotive maintenance is recommended for detecting the dye in your vehicle's system. These lights emit the appropriate wavelength necessary to make the dye fluoresce brightly, allowing for easy identification of any leaks. Using a manual UV flashlight provides better control and visibility of inspection areas, ensuring a thorough assessment of your A/C and radiator systems.
  • Question: Is this product environmentally friendly?

    Answer: Yes, Certified A/C Pro Car Air Conditioner Leak Detector Dye is formulated with environmentally friendly components. It helps you identify leaks efficiently, reducing the need for excessive refrigerant replacements that could harm the environment. By detecting and repairing leaks promptly, car owners can contribute to a more sustainable approach while maintaining their vehicles, promoting a more responsible use of automotive systems.
  • Question: How much dye comes in one bottle?

    Answer: This product contains 1 Oz of A/C Pro Car Air Conditioner Leak Detector Dye, which is typically sufficient for multiple applications depending on your vehicle’s system size. The concentrated formula allows you to effectively use a minimal amount while still achieving optimum detection results. Multiple uses make this dye an economical solution for regular maintenance or inspections across different vehicles.
  • Question: Where can I buy the Certified A/C Pro Car Air Conditioner Leak Detector Dye in Saint Pierre and Miquelon?

Ubuy offers an easy online shopping platform where you can find the product, often with various purchasing options to meet your needs.
