My Altima in signature has an AC refrigerant leak. I’ve topped it off 2X recently.
When using a gas sniffer, is the sniffer detecting the refrigerant or the dye?
I went to a shop today to make an appt to check my system and through our discussion, the tech told my that they don’t use a gas leak detector(sniffer/snake) any longer.
They evacuate the system, recharge it through the manifold gauges and search for the leak/issue and repair. Yes, the also pull vacuum after the complete repair. .
But my Q is about the sniffer. Is it sniffing for a R134a leak or the dye?
