Do I need to put in my ac system if it is fully depleted? I have a series 2 car.

 

I remember about 40 oz. total (3 and a half 12 oz. cans) from my days of repairing A/C systems in the 80s and 90s, but might be a few ounces different????

If you are using ACTUAL R12 and not Freeze 12 then watch the pressures and sight glass!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

bob gauff

 

wouldnt be better to use 134a??

 

I don't know, can I put 134a into an old system?

 

You've got a lot of nerve talking a/c recharge while the rest of us are freezing our buns off! jk

 

What can I say, I'm in California...we had a few nights in the 40s and there was mass panic....

 

Was it deliberately emptied of gas, or has it all leaked out ? If it was me, I would have it checked for leaks by an air con specialist, then regassed. I watched a chap test my Maxda Xedos for leaks a few years ago using high pressure nitrogen. Fortunateley there were none !

 

YES! 134a can be a better substitute, and has a leak sealer in it ,along with compressor oil.

Vacuum down ,then install 134a, i do it to all my older cars.
most imprortant its much less cost.

 

The car sat for 5 years then I found the compressor was shot so now. I took the old compressor out and haven't put the new one in yet. I assume there is no juice in it now if there is no compressor attached...

 

just go ahead and go thru normal procedues, watch your gages, keep things at standard numbers. probably should replace dryer at same time!

it will be OK

 

According to the bottom of the following page, it takes 3.4 pounds:

Replace any o-rings that are disturbed by disconnecting of lines.

Borrow a vacuum pump and use it to fully evacuate the system for at least 30 minutes, an hour is better. This gets all the water out and promotes better performance and longer life. You can sometimes get these pumps from auto parts stores loaner tool programs. Some AutoZone stores have them, but not all. Check with your local store, and ask if any of their sister stores have a wider selection of loaner tools that includes the vacuum pump for A/C work.
