How to Vacuum Recharge Automotive AC with R134A HFC134A Refrigerant

We vacuum the A/C lines in a Lexus IS300 after a compressor and condenser replacement project. We then recharge with 22 Oz of R-134a which is same as HFC-134a. We also refill the oil with ND Oil 8 (PRAG). Check the other videos and the list of parts below if you are doing this and need anything else.
You can borrow the vacuum from local autoparts or buy a new one on Amazon.

There are charts on the internet that show what the system pressure at the ambient should be. I charged my pick up today, and it was 100 degrees outside. My low side required 50-55 psi and high side at 285-300 psi. My vent temp was 30 degrees with blower on high. Your pressures seemed low, and vent temp at 50 is warm.

I got 40F discharge air with a proper vent thermometer. This is consistent with my other Toyota cars.

Very nice! Well explained

Glad you liked it and watched. Hope it helps for future DIY.

Excellent video

[@TunerwithKids]

Thanks for watching.

[@electric9977]

Why were you opening and closing the valve of the freon?

[@TunerwithKids]

Was trying to get it to flow so wasn’t sure since I didn’t see it move the sight glass. But it too a second to get going.

[@electric9977]

Same issue i was having, I wasn’t able to get the refrigerants flow to the system? Any advice what can cause that?

[@TunerwithKids]

@electric9977 those new “self sealing” cans are finicky. Sometimes the screw on nozzle has too much gasket and the pin can’t penetrate too. I screwed in all the way and was trying to hear the pressure drop and see the sight glass.

[@electric9977]

So i have to turn it all the way down and leave it as is?

[@TunerwithKids]

@@electric9977 no, turn it all way down to penetrate seal, the open to allow refrigerant out into the line. You should hear it and see if flow into the manifold.
