Charging a Vintage Air System For The First Time! How to Vacuum, Charge, and Test Your New Install!

Set up you gauges, vacuum the system, check to see that it holds pressure, add the freon, test the system for the proper pressures. New Vintage Air System installed and now it needs set up properly. This process will work on any automotive AC system.

So jealous! I cannot wait to get my vintage air system in. Looks like you did a great job Nate! Just like I learned in hvac school!

[@HeavyPedalGarage]

Right on! The vintage air kit was a lot of fun to put together!

[@benbunker2946]

Great info! Getting ready to do mine in my '76 C10! The tips at the end were especially helpful!

[@HeavyPedalGarage]

Sweet! Glad the video could be helpful.

[@ridenda67camaro]

Awesome video this is the video I’ve been waiting for :) thanks again

[@HeavyPedalGarage]

For sure! this was a fun project from the install to the charge. Super cool! ( see what i did there, lol)

[@rexracer537]

Another great video 👍🏾

[@HeavyPedalGarage]

Appreciate it. Thank you!

[@asicerik]

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!

[@HeavyPedalGarage]

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!

[@RST563]

great job

[@HeavyPedalGarage]

Thanks!

[@garyemery2497]

Great video I was wondering what color your car is. Royal Plum?

[@HeavyPedalGarage]

It’s a UreChem color called sparkling merlot pearl. I love it!

[@swampy6x659]

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

[@HeavyPedalGarage]

Great suggestion. thanks.

[@hdd5tgggg580]

Great videos. Question, what did you do to adapt the 5/8 hose going from the evaporator to the 3/4 nipple on the timing chain housing

[@HeavyPedalGarage]

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.

[@MrHevyshevy]

I put vintage air in my 72 Firebird. Does not keep car cool on hot days in here in North Carolina.

[@HeavyPedalGarage]

That's a bummer. Its been keeping up for me in ohio this summer. 85-90F It takes a while to cool a hot car down though.

[@bengonzalez1730]

Do you know what size orifice tube you installed on your system?

[@HeavyPedalGarage]

Everthing I used came in the kit. Not sure about actual sizes.

[@MattDavis-zs4mt]

All vintage air units have an expansion valve, there is no orifice tube

[@rogerfoltz4759]

what temperature at the vent read?

[@HeavyPedalGarage]

I showed a shot of it in video, but i think it ranged from 30 to 43F depending on where the lazer was hitting.

[@swampy6x659]

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

[@HeavyPedalGarage]

Ok. Right on. Thanks.

[@swampy6x659]

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 .

[@HeavyPedalGarage]

Thanks for the info.
