Well depends on how much is in there now if you look on the a/c contanier it will tell you how many pound's it takes. use a tester to see how much is in there now before adding and when adding make sure car is running and the a/c is on max when doing so.

Air compressor wont come on to to put in 134a


The AC compressor does not have to be running to charge the AC system, and the low pressure switch will even prevent the AC compressor from operating until there is sufficient pressure to operate the AC compressor without damaging it.

Start the engine and turn on the AC, then charge the system with the R-134a and as soon as there is enough pressure built up to trip the low pressure switch off, the AC compressor clutch should then engage and then finish charging the AC system.

AC has freon (134a) pressure is good. Compressor


Have a code reader or scanner put on the car to erase all codes,this should reset the ac system circuit.Also check the low side clutch cycle switch,it may be the problem.

Where do I put air conditioner coolant for a 2005 Malibu. I have found two caps but my 134a refrigerant will not fit either. I must be looking in the wrong place?


start from the compressor lines there is one go to the compressor and another comming out ,check for two entries one is big and the other small in the same line there should be two little caps blacks,unscrew one and see if fitts ,now you must have the correct pipe line wich conects the 134a can to the ac line,this you can buy one from autozone,one end will fit the can and the other will fit the ac line,good luck if you have any questions let me know i can send you a picture of the ac lines .

I need to retrofit and recharge my 1988 Dodge Ram Ac.


First, the old R-12 must be completely evacuated fromt the system. R-12 and R-134A do not mix and won't function together. Once you are sure there's no R-12 left in the system, you need to install an R-134A fill valve on the low side AC line. This is where your refill hose will connect to add R-134A. Once the valve is in place you're ready to fill the system. The compressor requires a minimum of 20psi to engage and should not be filled to more than 45psi.

RECHARGING AC SYSTEM

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
4.Insert the other end of the refill hose to the low side valve
5.Puncture the R-134A can with the screw on the refill hose
6.You should feel the system suction the refrigerant out of the can
7.Check for frost on the AC lines and the air blowing inside the truck
8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

Where ac charge ia done cant locate fittings


Ok, heres a tough one. In 1995/1996 car manufacturers switched from using r-12 and began using r-134a. If you vehicle uses r-12 you need to put a retrofit kit on you car in order to change to the new r-134a. The best bet for this is to have a repair shop do it as the system needs to be emptied and vaccumed down to check for leaks. r-12 is very harmful to the environment and needs to be handled accordingly. Once the retrofit kit is applied, then you can use r-134a and you are good to go.

01 mustang convertable i changed the ac compressor now what?


need to evacuate the system check the orifice tube put back together and re-vacuum system to remove the air from the system.
it's cycling to fast which means air in the system.

any air left in the system will counter any refrigerant in the system.

98 mustang squealing and ac


first thing to do before you charge it again replace the 'O' rings in back of the compressor also add some a/c oil because that will help the a/c compressor not to rattle this is the way I do mine I put in a can of 134A first and after that I put in the 134A oil and then I put in the rest of the 134A that is needed
I would disassemble the front brakes and check out the wheel bearings and sometime there is nothing wrong with them just need to add bearing grease but if they are scarred or damaged replace them
