New to A/C Work

use pag 100 oil and when its a new compressor you should use 8 oz. of oil in the system...you have to evacuate the system and hold a vacume for 15 minutes. your car takes 2.2 pounds of refrigerant.

I did mine for 30 minutes when I replaced my compressor last summer. Just make sure you vacuum the system, or you'll have a system full of air that you're trying to charge. If you don't have access to a vacuum pump, any HVAC shop should be able to do it for a very small fee. They'd probably do it for free if they were evacuating the old R134a out, but either way, it's a simple deal for them.

Or 34oz. Just put in 3 12 oz cans and be done with it. I just did mine. AC is freezing cold . Also, I know they say to replace the accumulator blah, blah, blah. I had an accident back in 11/2000 - St. Farm wrote it off - and the car sat for about 4 years before I began the rebuild process. The AC system had been empty all the while. I just replaced the AC condensor because it was smashed up in the accident - no accumulator, compressor blah, blah, blah and everything works like the day I first bought the car. Personally, I would not spend anymore money than needed to just evacuate and charge system.

Note: While charging make sure you have a water hose around because the high side pressure will rise and you don't want it to go above 150-175. Use the water hose to spray the condensor and you will see the pressure drop immediately to about 100-150. When you finish you will be proud of yourself and know that the shops can't screw you anymore.


Good luck
Peace
