As i draw down on my departure date to go to the emerald coast cruizin, i’m watching the weather. It now looks like i’ll be leaving Alabama at 80 degrees, and driving into 85 degrees.
Thoughts turn towards the drive......Do I want to drive 4.5 hours with the windows down, or do I want to be able to do that with them up?
Pretty simple really...Why the hell would I deal with 75 mph wind noise when I don’t have to?
That forced me to consider the AC systems state of charge.....specifically, how much oil is in the compressor?
Since the last time, when the old monster engine was in there, the AC system charge was blown to atmosphere ( I know,....bad Mike,....very bad Mike)
The 2jz put in place, 4 oz of PAG100 oil added to the compressor, and a failed attempt at recharging the system that had low side pressure high, and high side pressure low...
Take the thing to the dealership,...have them evac the system,..and wonder.....How much oil remains in the compressor.
Remove and exchange the drier...seal up the system,...and consider pulling a vacuum on the system prior to a second go at charging the system prior to the trip.
Enter the 3AMD....
” What if the compressor is dry?.....The thing will lock up in about 10 minutes or less if the thing is empty....Then you’ll have way more to deal with than removing compressor and turning it upside down”.
Ahhh fck.
So,......I remove the compressor. And turn it upside down.
Its empty.
Now knowing that it’s empty, I put the thing back. Now I gotta add back oil...What oil, and how much are answers that escape me tonight...I need to talk to Vintage air to know for sure.
And i’m doin all this...with only hours to do it, after work...with a 4.5 hour drive in front of me, on Thursday.
I have 30 oz of R 134...i only need 28. I bought 8 oz of PAG100 oil, but don’t know if that is the right junk...so I’m gonna wait till tomorrow night to deal with it.
Ill have to work till 6-7pm....then after talking to Vintage Air...I’ll add whatever they tell me to put in. Vacuum the system, and leave it...till Wednesday.
Then,....if there’s still the same -28” of vacuum on wed night, that i put on it on tuesday night...I’ll attempt to add the refrigerant.
