Just installed a vintage air system on my car and did everything the same in this video. Same little harbor freight vacuum pump and Amazon gauges. My AC blows COLD and works awesome!
You might want to clock your compressor so the oil filler plug is on top . The way you have it mounted its not on top. Looks like its over by the inner fender side. It could allow the oil to drain from the compressor when not in use, thereby not lubricating it properly. Also. Hope you didnt damage the reed valves internally. Sandens are a fixed displacement and are gas fill only. Liquid fill is highly noted in instructions of what not to do.
i cant remember specifically, but i have the Vintage Air, full install, video on my channel. You could check it out and see if you can find what you are looking for.
If you had the compressor power wire hooked up all of this time, would the binary or trinary switch have prevented it from coming on due to no pressure in the system???
Good stuff. I need to take mine into a shop to get all the fittings done. Good tip on the engine temp, I better make sure my cooling is up to snuff before dropping it off at the AC shop!
For sure> Its been a fun project. Nice to have cool air! Been watching your interior come together. I love it! Cant wait to see your "maro out on the road!
Reality suggests proper HVAC techs use is at least 4cfm dual stage vac pump upto 10cfm D/stage WHY vacuum equals a micron level . Level to achieve is under 200micron pump on / stabilize. at 200-1000 micron for upto 30 mins pump off . Charge by weight or bubbles in sight glass. Advanced charging [ fixed displacement compressor ] super heat sub cool . As u can do nothing about PSI H/L , thermostat temps etc If these are an issue there is a fault .Psi and temps are what they end up being .
A system with 50% charge will reach thermostat off point easily . What happens if u under charge the compressor oil does not circulate eg shortens life . Charge by weight / sight glass / subcool txv system / superheat if orifice system . 5--10f subcool at 1200 engine rpm or higher will be alot closer than current charge . U need to no gauge psi converted to temp f at the outlet of condenser or liquid line eg R134a gauge reading 200psi =131F USE A PT CHART Actual physical liquid line temp close to service fitting 120F The gauge avg the condenser The liquid line surface temp is exactly that Having a liquid line temp colder means there is cold liquid in the liquid line ,, this means the system is FULL
Evacuation removes moisture NOT impurities/debris Use di lectric grease on manifold o rings when new and flush with liquid refrigerant . This ensures no vacuum issues eg micron will not lower with grease in system
