SOURCE: AC Low Pressure location on 2004 Chevy Suburban

You find the AC low pressure at the top of the compressor, orientated toward you , facing the front of the vehicle. You can also follow the compressor line to reach the port.

The valve is covered a plastic cap covering it.
Near the compressor you find two ports, the high port and low port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports covered with plastic caps. Only one of the pipes will be cold, the cold line will lead you to the low port.

Regards.

SOURCE: where is low side ac hose for recharging located

You will notice the low side has a larger aluminum pipe, and along that pipe you will find the low side port. Anyways you can't connect the low side charging hose to the high side so there is no way you gonna make a mistake on connecting the can to the high side and blowing up the can.LOL

SOURCE: LOCATION OF LOW PRESSURE AC VALVE ON 1992 FORD

Valve is between accumulator and evaporator on the passenger side. Your van originally came with R-12 freon, so you will need to verify that it has been converted to R-134 before adding freon. The different gasses (and especially the lubricating oils) do not mix well.

Where is the low port located in the engine to recharge the ac for a 2008 Chevy Malibu LTZ 3.6 v6


The low pressure side to the ac will be the Schrader valve that is the smallest size. If you are recharging it yourself try to fit you valve on both valve and you will see what I am talking about.

How to recharge ac


There are many ways to recharge an ac system but to do it correctly is a bit more in-depth. You can read the ac tag under the hood of your vehicle and purchase a can of coolant then hook it up to the low pressure side as shown on the can. Start the engine and follow their instructions. If you have a leak you should add UV dye to the system to locate the leak then repair as needed. To recharge system I recommend purging the system to a proper catchment contaner, recycle the refrigerant as required. Put an ac manifold on the high and low ports of the ac system (they are sized to only fit in the proper location) then attach a moisture removing vacuum pump create a vacuum in the system of 20lbs at sea level or more. Close the high and low pressure valves and disconnect the vacuum pump connect the refrigerant to the vacuum line, start the vehicle, turn on the ac (fan on low) add the amount of refrigerant that your vehicle tag requires.

Low pressure valve for 2008 ford explorer xlt


There should be two ports with black caps on the ac lines. One is bigger than the other to help prevent you from hooking up to the wrong side of the compressor.

I attempted to recharge the AC. I first pulled a vacuum to 30". Started to recharge, low side pressure approx 20#, high side pressure approaching 400 PSi and tripping on high head pressure. What's...


I would say a restriction somewhere.. Likely the expansion valve itself. It should be located in the tubing just before the evaporator. You will have to recover that freon you just put in, pulls the valve and check it.

Low Pressure Valve 97 Grand Am


The low pressure valve is down by the AC Compressor. It is part of the aluminum manifold that connects directly to the AC compressor. It is accessible from above, but easier to reach from under the car.

By the way, is there any particular reason why you want to recharge your AC system? If it isn't working, adding refrigerant will not necessarily fix the problem. If the refrigerant has all leaked out, you probably need to evacuate the system first.

2004 Lincoln LS A/C Valve


In order to charge, you must locate the low pressure valve to install the refrigerant. The low pressure valve is between the compressor and the evaporator. Do not charge on the High Pressure side, The high pressure valve is between the compressor and the condenser. To locate the low pressure valve, follow the line that comes from the compressor and routes toward the firewall. The valve will be somewhere on that line. Do not overcharge. The amount of pressure that is needed on the low pressure side will depend on the ambient outside temperature.

AC has stopped blowing cold air. Compressor is working. Where is the recharge valve located?


There are two A/C refrigerant lines. The small line is your high pressure line and the larger line is your low pressure line.
Start at the fire wall and follow the "large " low pressure line to the compressor. The low pressure charge port will be some where on that line.
DO NOT try to recharge on the high pressure side ( small line )
Good luck, let me know.

Locating low pressure valve on 96 explorer for ac recharge


The largest diameter line is the suction which is low. The small one that runs to a coil by radiator is high pressure. If there is no cooling then you may have air in the system which means a leak must be fixed first. Are you sure the compressor is engaging? You should hear it click and the engine bog down a little.
