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.

Where is the low side on the ac pump located?


There are two ports on the ac lines covered with black caps. One is larger than the other to help prevent you from connecting to the wrong port. One is low pressure and the other is high when the compressor is running.

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.

How do I put freon into 1993 grand cherokee 5.2 engine?


Look for the large ac line/hose coming out of the ac compressor,and follow that line until you come to a small ac port,this is the low side where you will hook up to to charge.I take it you have purchased a charge hose and freon?Put the can of 134a freon on the can tap at end of charge hose,and the quick connect will snap on the low side ac port on the vehicle.Turn the freon can upside down and turn the t handle on the can tap until it pierces the can.Start the vehicle,and set all settings high blower motor,max air,recirculate mode.The ac compressor should cycle on and off,this is normal,until there is enough freon in system.When the can starts to empty,shake the can lightly until empty.It will be hard to tell,but you will figure it out.Turn the can t-handle back out,and unscrew the can an repeat process until enough freon is in the system.You can get to much freon in the system.so see hoe much it takes to fill it on the label under the hood.If the system was not empty,it won`t take the fill amount,go slow,and feel the cold parts(large ac line near the firewall).They should get dern cool,to cold,and sweating really good.Stop when this happens,and it is cool inside.

Where does the freon go for a 99 expedition


Hi .. I just ran into the same problem .. I have a 2000 Expedition with the 5.4L engine .. the low side port is located on the passenger side of engine compartment just below the black metal bracket that contains electrical connections right in front of the firewall... you have to reach under this and locate the low side (larger line) and feel for the connection .. it is right in front of the accumulator .. There are two heater hose that hide the port .. you have reach under these to unscrew the port cap which is black .. you'll have to do this by feel .. I have found that you can by R134A charge with dye and leak sealant helps with small leaks .. if the system takes more than two cans be usre to add refrig. oil .. hope this helps

How do I add coolant to the air conditioning system of my 2001 Hyundai Elantra?


You need to locate the low port on the AC.

You recharge the AC connecting to the low port.

You find the AC low pressure at the top of the compressor. Near the compressor you find two ports, the high port and low port.
You can follow the compressor line to reach the port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports , often covered with plastic caps. Only one of the pipes will be cold, the line that is cold will lead you to the low port.
