Re: Leak detector dye colors
A red refrigerant dye (NOT with stop leak) that FJC describes as "visual" is available. It's not fluorescent, and it doesn't glow brightly like the greenish yellow dye does using a UV light and special eyeglasses in a darkened shop. It might be sufficient for your purposes, though.

Re: Leak detector dye colors
Most of what you'll find for MVAC systems is the greenish yellow or green fluorescent dye, and sometimes but rarely, fluorescent red. The much better option IMHO is a decent-quality "sniffer"--electronic leak detector--that can sense even minute refrigerant leaks that the dye won't show. W...

Re: AC issues
Seems to me the refrigerant continues to leak out, shutting down the compressor. I don't think heating-up the car had anything to do with it. Hopefully, there was no sealer in the refrigerant can you put in. Sealer can destroy a system right quick. I suggest not jumping the clutch to force-engage th...

Re: Can I drive with my system before filling it up
Do you have a High Pressure Cut-Off and/or a Low Pressure Cut-Off switch (or a binary or trinary switch) installed? If the answer is yes, you can safely drive the vehicle regardless of whether the A/C system is turned on or off because the compressor won't engage anyway if the refrigerant is low or ...

Re: Should I try control valve or just replace compressor
it has 90K With 90,000 miles on the clock, the A/C system probably would benefit from a new compressor, along with a new OT and accumulator, which contains a desiccant. On a 2005 LeSabre it has poor cooling performance. At 80deg ambient, vent temp at 72deg. Low side is 55-60, high side 170. Thought...

Re: Peterbilt AC potential evap problem
Is it possible there to much "gas" in the system vs liquid refrigerant? It's a sanden compressor, maybe its bad yet again? thanks for any help. Was this system converted from R-12 to R-134a? I doubt that it's the compressor failing. When you hear that hissing sound, it usually means that ...

Re: Should I Top Off My 16 Year Old System?
Remember that whenever you attach your Manifold Gauge Set (MGS) to a system, you lose some amount of refrigerant that (when you disconnect the MGS) remains in the hoses. How much depends on the length of the hoses, and also how much remains in the gauges and the manifold itself, if any. With a compa...

Re: Should I try control valve or just replace compressor
I agree with Tim.
Although the compressor might be "tired," pressures can often throw you off with a variable-displacement compressor. Best to weigh-in the OEM-specs charge first, then see how it performs.

Re: Question re minimum safe refrigerant amount.
Thanks for the good ideas. The local Community College has an auto AC class, but only in the spring. I'll seriously consider taking it next year. It's free for seniors... Good timing that the CC offers the class in the Spring, just when people start thinking about getting their MVAC systems in shap...
