I recently replaced the the AC condenser because it had a big hole in it when I acquired the car. It's installef and I'm ready to create vacuum and add freon. No caps and they look the same Is this setup correctly for high and low port?
You will not be able to connect the manifold gauge set hoses to the service ports incorrectly.
In the Maxima system, the low side port is the passenger side high position and the high side port in low (radiator) position you’ve got your connections correct.
Also, based on the fact that you’ve actually connected the gauge set, you’ve connected things correctly.

Hey thanks. I'm trying to keep from getting stuck on stupid but I was unable to get any suction because of this yellow line. I'm guessing there's some adapter that was not with the loaner kit. So I'm doing each side individually using the manifolds red and blue cables directly to the vacuum pump. Been vacuuming for about 45 minutes each side. I don't see any more mist coming from the pump so maybe it's ready. A picture of the freon I plan to use it's exactly 18 ounces which is I think the requirement. And the end of the yellow manifold cable which has me scratching my head. There are no other parts included with the loaner kit just three hoses and the manifold
It was empty because the condenser had a hole. And because system was empty i took the eady route to replace alternator removing compressor
Vacuumed the system for an hour to make room for freon test for leaks and get rid of moisture. It's hard to say what the vacuum pressure was. The needles on the manifold gauge stayed pegged on zero for an hour after vacuuming so there didn't appear to be any leaks. Added what the green AC sticker under the hood specifies.
One thing I should mention is that can of freon in the pic above hurt the schrader valve. The hose and connector it came with didnt seat proprly on the low port. So i pushed to get the freon in. Big mistake. It was nice and cold then when I shut car off I could hear the port hissing. Out of desperation I put a tiny screwdriver down the port and wiggled. It worked, stopped hissing. So I lost a little. Going to top off later with a different bottle and connector. Lesson learned if it's tight on the port don't force it. Better off using a twist type like the manifold. Something metal. Maybe the acpro connector is better. But im not sure i want to try.
thanks for posting this, I wanted to know how much vacuum should each side hold before adding the freon?
There is no “amount” of vacuum you’re looking for. You’re simply looking to create a vacuum in the system. Based on the fact that we’re on the planet earth, the maximum vacuum pressure that can be achieved is between 29 and 30 in. Hg.
When applying vacuum to an A/C system, the vacuum shoul be applied for at least 45 minutes to ensure that all atmosphere has removed and all moisture has boiled off.

Thanks for that information gonna be doing the same thing this week

thats at a higher altitude? If you live in FL or in a place closer to sea level i dont think you really need to pull a vacuum. How much pressure would you really be removing in FL?
