Where is the AC valve on a 2000 Chevy Malibu?

Question

I want to refill the R-134a.

There is no leak. The system is partially empty. I do have a measuring tool & know how much pressure there should be. I'm simply asking where the valve is.

Answer 1

This is one of those questions that if you ask, you should not do.

Is it empty or low or full and not working?
Do you have a vacuum pump to evacuate the system first? Do you have a guage set to know if and when it is evacuated properly to begin filling?
Do you have a scale to measure in the correct amount of Freon to within an ounce of optimum?
If your system is empty or partially empty, did you find and fix the leak? If not, you are wasting money and might as well just dump the freon into yur backyard.
I do not mean to be harsh, but sometimes you have to stop being penny-wise and pound-foolish.

Your vehicle is not old enough for a long term leak. You have either a big leak or a malfunction.

Answer 2

Do you have any experience with a/c systems ? If you overfill you can damage the compressor. The a/c low side valve is the fill side. It will be in the area near the compressor. There are two valves that are quick disconnect type. Be sure to use the larger of the two as the smaller is the high side and has around 140 psi. Be careful. Be sure engine is at idle and A/C is on before you connect the can of 134A or the can may explode.

Answer 3

You should NOT be trying to fill the AC on any car. If you have the training, and you do not, the you would understand.
It is vary easy to over fill or under fill the AC. It requires special equipment to work on it.
You MUST repair the leak before you fill it.
You could also hurt yourself or damage the system with out the right training.
