Mission Accomplished. Thank you ALL!

Year: 1979
Make: VW
Model: Rabbit C
Engine Size: 1.8
Refrigerant Type: r134a
Ambient Temp: 84
Pressure Low: 25ish
Pressure High: 225ish

Well I'm officially done with the conversion/upgrade to the rabbit.

I had taken it to the shop today and had the system evacuated(had 12oz), vacuumed and refilled to 100% capacity(32oz). On the way home I QUICKLY learned that it couldn't handle that! The whole way home my comp cycled on and off and the vent temps were in the mid 60s. When I got home I checked my pressures and idling it was over 300. With a little rev it went over 400 with ease.

Thankfully I installed the cutoff switch ackits sells and it saved my a/c system by shutting it down!

After evacuating an unknown amount I took the pressures down to 225-250 on the high side and saw a minute amount of bubbles in the glass(zero bubbles with 32ozs). I took it for a spin and in 84 degree weather the vent temps got down to 47. That's nearly a 40 degree drop and the wife was very pleased.

Overall I'm very happy with the system and I can't thank and this forum for all the incredible help.

An airconditioned hippy,

400 PSI, Have to wonder what type of PF condenser you got!

Let us know what its like when the summer hits. Glad the forum could lend a hand with your a/c questions.


When considering your next auto A/C purchase, please consider the site that supports you:
