Why can't they make it like a maverik beer cooler? AC in cars is not good enough unless you drive for along time!

@thebandit4393 4 күн бұрын

Unfortunately the size of a car means there is a lot of surface area for heat to come through, not to mention all the windows and doors that are difficult to seal completely. You can however make a big improvement with insulation, especially on the firewall, tunnel, and floor where the engine heat tends to bake the interior. These olds cars aren't engineered to be sealed up or insulated like new cars - plenty can be done 👍

Where did you get the j shaped fitting coming off poa valve to make new line to compressor? And what size is it? I have a 70 Monte Carlo and trying to get new lines made for my ac compressor on my ls6

@thebandit4393 Ай бұрын

The POA valve has a #12 o ring outlet. I used an Original Auto Air aka Classic Auto Air PN G13-407 Shepard's hook which takes it down to #10 barrier hose. Another option I tried that did not fit well was Nostalgic Auto Air PN G135.

Thanks for the great video. I have a question about the pressure setting for R134a. I see you set your pressure to 26 psi on your POA valve. When I look at a pressure chart for R134a it shows a set pressure of 27.5 for a evaporator coil temperature of 32°, I'm just curious if you have ever encountered a coil freeze up at the 26 psi pressure? I'm getting ready to make this adjustment on my POA valve. Thanks again. I look forward to your reply.

@thebandit4393 4 ай бұрын

I have not experienced a freeze up. I know some people go even slightly lower on the pressure. I suspect the expansion valve control of superheat would keep freeze-up from happening since the outlet temperature is kept a few degrees above the saturation temperature.

I agree one of those would be a nice upgrade. Since this video was taken I switched to a Grant Corsa GT which is a low buck wheel similar to the Monte Carlo. I plan to upgrade to a nicer wheel like a Momo, Nardi, or Sparco. One I particularly like is the Nardi Gara 3/0. There aren't many steering wheels that look right in this car and also have the ergonomics and gauge visibility that I prefer. The old Grant Challenger wheel in the video had a nice thick grip but the overall diameter and spokes weren't ideal.
