Have a '96 Saturn SL2 with the factory R134A system.
I professionally evacuated and recharged the system with the correct amount of R134A refrigerant (1.5 lbs) in June 2009.
Last week, in 70F weather, I noticed the A/C performance was mediocre at best. Given the 70F ambient temperatures and medicore cooling performance, the system was evidently undercharged.
So, I added 1/2 can of R134A[/quote]. At this point, the system was cooling well for 70F weather so I left it alone.
Today, we had a wave of warm weather. Temperatures were in the upper 80s, and I'm sure my car was over 100F after being parked in the sun for a while. The A/C system was again, mediocre for the 80F+ heat, but once the outside temperatures cooled down the A/C was working fine again. So, I added the rest of the can of R134A (for a total of ~11 oz) and the A/C seemed to be even colder (even though it was now nighttime).
It is very likely for the system to be slightly overcharged by a few ounces. At the same time, I am quite certain that I have a leak somewhere, so I'm sure it'll leak out. But if it doesn't, what kind of issues will a few ounces of overcharge cause?
Thanks!
