Re: Metric to SAE/standard A/C plumbing questions
I worked in an industrial chemistry laboratory for over 4 decades. SwageLok fittings are absolutely the best, and the by-far most-common fittings used in gas (and liquid) chromatography. What that means for us here is that these fittings were leak free for hydrogen (explosive) and for helium molecul...

Re: Should I Top Off My 16 Year Old System?
But I do agree with the point made above. If you aren't having any problems with the system currently, I would leave it alone. Disclaimer: I am NOT an AC professional. I also agree that if you feel comfortable and cool, then the system is working fine, so do not attach gauges or "top off"...

Re: Question re minimum safe refrigerant amount.
It seems to me - and I'm NOT an AC professional - that manufacturers over the last couple of decades have gone to smaller driers, so that fewer ounces of refrigerant would be required, a cost savings. Given that, over or under such reduced ounces of refrigerant give poor performance. I'm from the co...

Re: Noise after AC service
I'm thinking to replace the fan clutch to improve air flow at idle and slower-speed driving. Or at least test it well.

Re: Broken AC high side cap - 1998 Nissan Frontier
My 1998 Frontier uses a red high side cap and a blue low side cap, no H or L on them. They look pretty much like the ones shown here. https://i.imgur.com/B7DnSaF.png My 2004 Frontier with essentially same engine, transmission, and AC has two black caps of same shape as the red and blue ones. Both Fr...

Re: Broken AC high side cap - 1998 Nissan Frontier
Cusser, I believe that auto manufacturers make their caps with proprietary threads and size differences inside because I've had the same problem as you with replacements not threading on. Why they do that is anyone's guess. One would think that the caps would be standard across the industry with on...

Re: Broken AC high side cap - 1998 Nissan Frontier
Apparently, there are differences/two types of red high side R134a caps and also differences/two types of blue low side caps, see the photo below from a replacement cap assortment, see the differences. But I don't know what the internal differences are - anyone know ??? https://i.imgur.com/B7DnSaF.p...

Broken AC high side cap - 1998 Nissan Frontier
Since Arizona has already had a few 100F days, I noticed that the AC in my 1998 Frontier wasn't as cold as it had been, and the AC compressor clutch was cycling way more than it had in the previous 20 years (I have a dashboard light in parallel to the AC clutch so I can monitor this). So today I wen...

Re: AC service caps for Honda, do they provide seal the AC system?
I've encountered just a few service valve caps that leaked. One was on a R-12 refrigerator from the late 1960s that lost its charge due to a crack in the seal of the service valve cap (like with vehicles, never expect a service valve schraeder to seal 100%). And a couple of years ago one of the valv...
