You need to add it to the Low Pressure Port which is on the Passenger side Firewall above the "computer" or PCM as well as your Coolant Recovery Jug. Keep the can in an upright position and turn the A/C on to recirculate, blower motor on High, all windows down and have someone accelerate the Engine to approximately 1500 RPMs. The port has a Black screw cap on it and if needed to find in the future, take Papermate® White out, and place a white dot on the Cap for future reference. Remember to close the Valve before disconnecting and since the pressure on the recharge line is lower at 1500 RPMs, disconnect it while it's running.

Hope this Helps you,

I fully charged the air. It reads full. But the compressor kicks on and off every 10 seconds. And the air is warm. I used Artic Freeze Ultra Synthetic R-134A It came with a gauge assembly.


Overcharging your a/c will cause it to blow hot .The on and of issue may be caused by the High pressure cycling switch . overcharging may be the culprit as well. you need to find out how much r134-a your system takes .

How many bottles of refrigerant a volvo s80 takes?


That's a REAL GOOD question! The factory refrigerant charge specifications for your vehicle is 2.20 Lbs. of R-134A. Freon R-134A comes in 12 oz, 14 oz, 16 oz, 19 oz, and 22 oz cans (as well as 30 Lb Cylinders) - it depends on which brand/size can you are buying, whether your system is COMPLETLY out of freon, or whether it still has some freon in it.

The best way to deal with the situation (in my opinion) if you are going to try and charge you own A/C system is to purchase a kit that comes with a gauge. A company called interdynamics has a real good kit available that comes with a reusable gauge. Once you have the gauge, all you have to purchase in the future is the freon itself. By using the gauge, you can more accurately charge your system without the worry of possibly overcharging. (Overcharging can cause extremely high pressures that can do serious damage to your vehicle or cause personal injury.)

Anyway, this kit is available at O'Reilly's as well as other auto parts retailers. Here is a direct link to see the kit at O'reill'ys web site.

There is also a whole bunch of instructional videos on how to charge your system at the interdynamics web site. CLICK HERE

Cannot locate valve to add 134a refrigerant in a 2000 lincoln navigator


What your looking for is called a service port. On a 134a system there are two of them, located in the refrigerant lines. One port will be larger diameter than the other. The large one is the "high" side and the small one is the "low" side. refrigerent is added to the low side with the system running. You really should use a manifold gauge set to see what the pressures are before adding any refrigerant. If the system has too much, it is as bad as not enough.

Air conditioner does not cool in 2000 Yukon.How do I check freon level and how to replace freon if need be


Get an r134a refrigerant add kit from Walmart or your local auto parts store.

You can even get a can of Arctic Freeze by Intermatics that has a hose and a gauge on it.

Connect the hose to the low side port. You can find this port on the 'thicker' piping that comes off of the compressor (versus the thinner piping that comes off the compressor which is the high pressure side).

Pressure should read 25 psi to 45 psi on the low pressure side when the compressor is running and the a/c is on.

Pressure should read 75 psi to 100 psi on a hot day when the car is off.

However, you'll want the a/c to be running when you add freon.

Press the button on the can to install more freon, if needed.

When I try to use my 2002 BMW X5 heater or AC, neither cold nor hot air blows, but air is being moved. How can I figure out what the problem is?


YES, THE LOWER PRESSURE AC PORT IS AT THE PASSENGER SIDE OF THE CAR.
IF YOU OPEN THE HOOD YOU WILL SEE IT , BY THE WINDSHELD WIPPER TANK. ALSO THE LINE AS A BLUE DOT ON IT. AND A BLACK PLASTIC CAP.
THERE IS ALSO ONE BY THE RADIATOR BUT THAT IS THE HIGH ONE.
YOU WILL NEED THE LOWER ,PORT TO FILL UP THE AC UNIT.
ALSO STAY IN THE BLUE , NOT WHITE OR RED. READ INSTRUCTIONS ON CAN !!!
I USED THE ARCTIC FREEZE ULTRA SYNTHETIC 134 A REFRIGERANT. PEPBOY ALSO WALMART HAS IT.
I BOUGHT THE 134 CAN TO FILL UP THE AC UNIT , AT FIRST IT DIDNT FIT BUT THEN IT WORKED. I TRUNED ON THE CAR AND THE AIR ON HIGH.
NOW AM GETTING VERY COLD AIR.I ALSO CALLED THE DEALER AND THEY WANT $ 250 , TO DO SOMETHING THAT YOU CAN DO FOR UNDER $ 15 DOLLERS. THE DEALER DID TELL ME THAT THEY ALSO CHECK FOR LEAKS AND THEY ALSO EMPTY THE AC UNIT BEFOR THEY REFILL IT .
I HOPE THIS INFORMATION WILL HELP , WHEN USING THE 134 A CAN ! YES IT DOSE WORK AND IT WILL FIT .

1996 jimmy air conditioner blows hot air worked fine a couple weeks ago. I used the arctic freeze ultra synthetic refrigerant 134a+ but didnt seem to do any good. Still blows hot air.


Might be the condincer, does the comprsure kick when you turn the air on. if so you might want to take it to a shop and have them flush the lines out. old as it is it should be done, another thing to check would be the temp snsor for the a/c.

A/C is blowing out hot air and need to know how much refrigerant is needed


interdynamics makes a neat little setup for r134 install. It's a trigger release can top with a hose that fits right on the system. it has a "dummy proof" gauge on it that tells you how much is in there till its at the right level. I have a full set of gauges and use the easy can more than the gauges! (I double checked several times and the can thing does read correctly) There should be a charge label on the compressor or on the radiator cowl.
