Yes you can do that. Since R134 can be purchased without the need for a license. I must mention tho not to release refrigerant in the atmosphere because even tho 134 is considered not as damaging to the ozone it still contribute to global warming. Plus it is still required by the EPA that you must use a recovery device when servicing a 134 system, you can add some in there without the need for recovery device. Before you do so connect the gauges. Make sure the hoses are clear then start the car and turn the a/c to maximum as well as the blower. You should have all the windows close ( make sure you don't get locked out). As the inside of the car cools down, the pressure on the low side will drop gradually, as it reaches around 35 PSI, then as it reaches what you call a cut off pressure the compressor will cut off then the pressure suddenly starts going up again untill it reaches a certain pressure then the compressor kicks in again. If this cycle happens too often say every few seconds or so that means it is low on refrigerant. If this cycle does not happen at all, then either there is air in the system, or it is overcharged. If there is air in the system or it is overcharged, it wont cool properly, and it can damage the compressor over time. All these peressure reading are on the low side. Recharge kit only have low pressure side gauges. Warning: Never charge an A/C system in a car on the high side, the can will burst and can cause injury. Good luck

You definetly can just keep in mind that it will not be a great amount of freon as when a proffesional shop does an a/c recharge and revac. The first thing you want to do is look for a plastic cap that is near the a/c resavior and remove it. Then just press on the bottle of freon and give it a couple of minutes to transfer through.

Hope this helps!

How to add freon to a 2002 chevy malibu

If I remember right, the AC lines on GM are usually on the left side standing in front of the vehicle. Should be one big tubing and one smaller tubing. The big one is the suction line where you add the freon. You should find a plastic cap in the charging port. You need a can of freon and the proper snap on hose connection to fit the big tubing. Some recharge kits have the hose and a pressure gauge attached so you can watch how much freon you are adding. I recommend this type kit. You add freon with the car running and watch the gauge until the needle points to the green area. Watch removing the hoses since there will be some freon in the hose that could cause frost bit or skin burn whe removing it.

How to recharge ac

For DIY folks, you get a recharge kit from an auto parts store and connect it to one of the ports on the ac line.
Instructions come with the kit.
Keep in mind freon gas is about 30 degrees below zero coming out of the can.

Please advise how to add freon to mitsubishi montero '01 air conditioner unit

The best thing i can tell you is to take it into a shop. You can add freon to a system but you need to know what kind your vehicle needs. If it takes the new current freon your in luck you can buy a recharge kit at any local parts store. If not you have a few options. You can get a conversion kit to change the system over to the new freon or you can try to find a shop that can recharge it with the older freon for your vehicle. Since its an 01 it should be the new freon but i cant be sure. There is a fitting with a cap on it on you AC Lines. should be 2 a red cap and a green cap. You remove the green cap and with the engine running attach a recharger bottle from the store and refill the system. Note the freon recharge kit will come with some instructions to always read them first. hope that helps good luck.

1) need freon 2) A/C/Heat won't turn off

In '92 most cars were still using r-12 freon, but some were using the newer r-134 freon. If its r-12 you need to have a repair shop recharge it. And they will probably try to sell you on converting the system to take r-134, which wont be cheap. If its r-134 you can buy a can with the regulator hose at any auto parts store for under $30 and as long as you know where the low pressure port is you can recharge it yourself. Just follow the instrucions on the can. Good luck, I hope this helps you.

Air conditioner not blowing cold air

go to a parts store such as Advance Auto Parts or Auto Zone and buy the A/C recharging kit they have with the rubber line and connector that connects only on the side that you need to recharge your system. If you can put air in your tires you can out freon in your a/c system.

I have a 2002 pt cruiser and my ac is not colling

Your car ls most likely low on refrigerant. If you're handy, you can get a recharge kit at an auto parts store to recharge your AC system. If not, most service stations will recharge the system for under $100 but be aware that they are mandated by law to detect any leaks prior to recharging the system. If a leak is detected, they must repair the leak prior to recharge which would lead to a more expensive repair. Best of luck.
