Where do I add frion to my 2003 chevy malibu


To the suction port, or low pressure side of the system. If you do not know what one that is, you might want to get some help. You need to have the proper amount of freon in the system or there could be compressor damage.

Where is the opening to add freon on a 2000 buick lesabre


I have a 2000 Lesabre and it is located on the passenger side of the engine compartment right on top of the Canister. There are two ports, one is larger than the other and both have a threaded plastic cap on them. The smaller one is the low side where you can check your R-134 pressure. Start engine and run the A/C on MAX. Remove the plastic cap from the smaller valve connect your gauge to that valveFollow the instuctions and tempurature specifications on the R-134 package. f9068a37-e087-4f01-b346-ecdafc697251.jpeg 587e478d-1464-4e2e-8ad9-44bf76552d6f.jpegThere ya go man, as you're hooking up the refill line hit the trigger so u don't allow any air in the lines instead of just straight freon.

The AC in my 2003 VW Convertible is not chilling enough. What can I do about it?


Your system may just be low on freon. Most auto parts stores sell 134a freon for about $10 a can. If you visit an Autozone store the parts counter personnel might also show you how to add freon to the VW Beetle, it's not hard once you know where the correct port is located. You simply start your car, connect the freon dispensing hose to the AC port (there are two (2) ports, but the hose connection will only fit onto the smaller of the two (2) ports - the low pressure side). Allow the car to run while the can is discharged into the AC system, generally takes 10-15 minutes. Most dispeners have a freon pressure gauge on the hose portion that attaches to the can. Never disconnect a partially empty can unless there is a shutoff valve, and the valve is closed all the way. Better to add the entire can to the AC system.
If you have never added freon to your 2003 VW Beetle, that's the most likely problem. You could also have developed a slow leak in the compressor or AC lines, so I recommend adding freon WITH a sealant in the same can just in case.

The job would cost between $45 and $65 if you take it to a reputible mechanic to perform. That usually includes a full blown pressure test of the AC system. and a whole list of costly recommendations.

What is the correct pressure for freon in AC unit and what is the color of the cap where you add the freon?????


The charging port cap is usually blue, The charging fixture hose will not clip onto the wrong port, so you really can't mess that up. the pressure of a system as measured on the low side hose should be about 28-32 PSI with the system stabilized and engine at operating temperature.

My air conditioner quit cooling. i was going to add freon but cannot find the low pressure port. it has 2 ports on the same line and my fill tool will not fit but one. the freon will not go in.


The ports are keyed - you found the proper port if you have the proper hose. If the Freon will not go in - and you have complied with all the package instructions ... right? ... Freon is not your problem. Going much beyond what you have done already is dangerous. Please have your AC looked at by a licensed AC Service Mechanic.

Thank you for your question @ FixYa.com

How do you add freon to a 1996 nissan maxima?


It is the same as with any other car. The freon must be added through the low side service port. If the freon is low, it means that there is a leak. It is recommended that you find and fix the leak before charging the system with more freon that will just leak back out.

AC blows warm. fan + compressor don't seem to engage.


The system could be low on refrigerant. The A/C pressure switch will not let the compressor run if the system pressure is below 28psi or above 455psi to protect the compressor from damage. At low pressures not enough oil (mixed in with the refrigerant) will circulate, and at high pressures, the compressor seals will likely blow. You can get a set of A/C manifold gauges for R-134a and check the system pressures yourself or get a shop to check it and possibly add some R-134a. If the system pressure checks good, then the A/C pressure switch, the compressor clutch, or some relays will need to be checked.

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.

Need to change out a/c pressure switch on a 95 chrysler cirrus .is it hard to do? 2.5 engine


it is not hard to do just be certain you have the proper socket wrench for removal and installation, proper way to do it is to have the system evacuated with a vacumn pump but if you want it done quick and cheap, be sure the engine is off as well as the a/c...just loosen the switch, wear protective clothes and googles so freon doesn't blind you or give you a spot of frost bite on your fingers when removing the switch. Make sure the new switch has thread sealant on the threads before installing to be certain the threads on the new switch wont allow any freon gas to leak out when the system is running.
IF YOU LOST A LOT OF FREON GET A FREON INSTALL FITTING KIT WITH AT LEAST TWO CANS OF FREON 134A AND INSTALL THROUGH THE LOW FILL PORT WHICH IS THE SMALLER FITTING THAT IS EMBEDDED INTO THE LARGER DIAMETER A/C LINE, (sorry for the caps) .............. make sure you have the a/c system on high blow full a/c and the engine idling while filling the system, if the freon wont gho in due to the a/c compressor clutch not engaging jump the new low pressure a/c switch connector out with a jumper wire accross the two wire terminals until you are done charging the system.
Hope this helps.
Happy Motoring!!
