Yes, the dye will continue to work in the same way.
Automotive A/C systems are closed systems that are subject to harsh weather and road conditions. Your A/C has plenty of places for leaks to occur in metal components like the condenser, evaporator, accumulator or receiver/drier, as well as in the rubber components: hoses, O-rings and gaskets. The refrigerant in your vehicle’s system only gets lower because the system has developed a small leak, which over time, causes you to feel warmer air blowing from the vents. Typically, refrigerant leaks occur in cars that are over five years old because the rubber O-rings and gaskets that seal the different components of the system have become brittle and dried out, allowing the refrigerant in the system to leak past them.
The best way to find leaks is with our R-134a UV Leak Detection Kit (part #436) which provides UV dye, high-intensity UV light and yellow-tinted protective glasses.
Yes. The dye will not affect A/C performance.
