alright guys, let me know if I'm forgetting something....

My A/C has not worked since I got this car but, it's summer and I knew it's time would come. I have on order:

O-ring set
receiver/Dryer
2 12 ounce cans of R12
1 can of R12 Oil charge
1 Pressure Gauge
R12 Service hoses
1 Vent thermometer

So here's the plan...I bypassed the low side pressure switch and the compressor kicked on...SO, All I should have to do is:

1. Check the system to verify there is no pressure. If there is pressure, I take it to a shop and get it evacuated.

2. Install new O-rings and Receiver/Dryer

3. Pull a Vacuum to at least 4 in of mercury and let the system set for a while then come back and verify that the Vacuum held. If the vacuum did not hold fix leaks before proceeding.

4. Charge the system from the low side svc fitting starting with the oil then Freon to 25 ounces with the system running.

5. Verify a cool breeze and ride happy.


And that's all there is to it right?
