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.

Audi A4 Ac charge valve.


On that year a4 and a6 there is no low side charging port. (sucks)
The way you charge those systems is by evacuating all of the refrigerant, then with the vehicle off, add the correct amount of refrigerant to the high side port (turning the compressor over by hand occasionally)

2002 ford expedition air conditioner needs R 134 refrigerant. I cant seem to locate the service port.


The low pressure valve on the 02 expedition is located on the accumulator on the passenger side fire wall. The accumulator is underneath the battery relay and a grouping of wires. Had to squeeze hand underneath a heater2_bing.gif hose and an a/c line to remove cap and hook up hose. Nothing has to be removed to locate the valve just a little touchy feely. Valve faces a 45 forward toward the engine.

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.

please rate as fixed if this helps you.

The low pressure service gauge port valve is located on the evaporator to accumulator/drier suction line.


The evaporator to accumulator/drier suction line contains low pressure refrigerant gas and is equipped with a serviceable low pressure A/C charge valve port.

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.

Where is the AC Low pressure valve on a 1999 Pontiac Grand Prix?


sometimes its behind the alternator real close to the firewall. Find the bigger of the two hoses and pipes the low side is always bigger. Also the cap is blue and the fitting for the charging can will only fit on the right valve.
