Honda Accord A/C Pressures

echeeves on Wed June 11, 2008 12:58 PM User is offline

Year: 1992
Make: Honda
Model: Accord
Engine Size: 2.2
Refrigerant Type: r-12
Ambient Temp: 90
Pressure Low: 21
Pressure High: 140
Country of Origin: United States

What do you guys think of the pressures? Blows slightly cool, white and foamy in the sightglass.
I also have colder air out of the passenger vent and vents get a little warmer as you move toward the drivers side? any ideas on the reason for that?
Thx to all....

It's undercharged. Check for leaks, repair if any found. On a true R-12 system you can go by the sight glass for topping up, charge until it runs clear.

Should I be concerned with adding oil to the system? if so,can I use bva 100? I have some on hand. I bought the car used so I don't know what oil is in it.
I just purchased some R-12 and was planning on doing this Sunday.
Thanks in advance....

How does the compressor sound? If there is a little noise to it you probably could get away with adding 1 ounce of oil. But check the connections for signs of a leak before adding any.

If this system is indeed still R-12 you should stick with mineral oil, but Ester is also suitable. You will need an oil injector to add oil to a system that is already under pressure. Too much oil is bad so unless you have noise from the compressor or evidence of oil leaking out you should not add any. Do spend some time looking for leaks.

I do not have any sound from the compressor so I will not add any. I will check for any oil around the fittings and proceed from there.
Thanks for your input guys.....
