Where do I add freon on a 2006 Ford Mustang GT?


If your system is blowing warm I would recommend having the system evacuated and check for leaks. Just adding Freon will not give you ice cold A/C. There are two valves, low side and high side. Usually the plastic caps are blue for low side, red cap for high side. If you use a commercial A/C machine to service the vehicle, both valves are connected to check pressures in the system and also to fill the system with the correct amount of Freon. The low side (blue) is located at the firewall near the dryer and the high side (red) is usually on the passenger side near the radiator.

Where is the expansion valve located on the 2004 KIA Sedona


Kia Sedona expansion FRONT valve located under dash, behind glove box, fan and coil. Evacuate freon first. Disconnect Freon lines from firewall., Lay right front seat back to flat horizontal position and lay on top or totally remove the seat for easier working access. Remove under dash cover, fan, glove box, coil housing, remove coil mounting bolts, remove old expansion valve. (Inspect old valve, if debris inside, blow out coil before installing new valve. If visible debris best to consider replacing REAR expansion valve and DRIER/FILTER in front of radiator too and blow out all lines and coils while servicing.) Use compressor oil to lubricate "O" rings on new FRONT or REAR expansion valve, install valve bolts, reinstall coil bolts to FRONT firewall or REAR frame, reconnect freon lines to firewall in engine compartment. Evacuate AC system, install freon (35 1/2 ounces, nominal 3 pounds), check system for leaks, check for proper operation, enjoy.

How do I fix a Air condition blow out hot air?


Go to your local auto parts purchase a a/c charge kit for about $69.00, find the low pressure(suction) fill port, there are two ports in every a/c system one is a low pressure side used primarily to fill a system with freon 123a or the like and it is the larger valve mounted on the line, then there is the dangerous high side valve, this is a smaller diameter valve mounted to a smaller diamet a/c line, this is under extreme pressure so donot attempt to fill this high side with freon as it can backfire on you and cause injury.
The low side fill kit will not fit on the high side port so thank godness for that.
start the vehicle put the a/c on full cold high blow fan speed, start filling the low side with a can of 123a freon+oil additive, which equals one pound of freon and check the inside a/c vents, getting cold? If its perfect then you are done, the system may have a very small slow leak and if it only takes a one pound can to fill it once or twice a year you are ok, if it takes more you may want to add a second pound can of freon 134a containing a dye additive that will work its way into the system and show you where the leaks are by exposing a color once it hits the air coming out of the systems defective seals etc.,also they sell a sealer + freon one pound can that can be used to try to fix the leak without having to get too expensive on the repairs.
A car's air conditioning system only hold like 2 3/4 pounds of freon, so in the event you happen to over fill the system a high pressure blow valve usually mounted on the a/c compressor will purge off the excess, but let me warn you they blow off without any warning and can startle you. Always think safety first, wear protective equipment. Work Smart, Work Safe.
Happy Motoring!!!

I put a hole in the freezer compartment, did I really just ruin the fridge? What would it cost to repair? and where do I get the parts?


You would need to clean the area around the puncture real well and get some epoxy putty to repair the hole. Allow for the area to dry and harden at least 24 hours.
Then you would need to evacuate the system to make sure no moisture is in the sealed sytem or ice will form in the lines and block the flow of freon. The system will only hold about 1/3rd of a 12 ounce can of R134a which anyone can buy a a automotive arts store. You would need to find a way to tap into the system to charge and vacuum it. The old folks used to purge a system instead of vacuuming it. The newer freon is environmentally safe so no special card is needed to purchase it. However it is still dangerous. You must not breathe the stuff or connect it to the high side of the compressor. The discharge side willl always be the high side and it will always go to the cooling condenser and is small steel line. An ear coming out the compressor is an ideal spot to connect a saddle valve to tap into the system. Before attaching a saddle valve you will fair better if you sand the copper down to prevent leaks. A saddle valve can be purchased at any appliance parts store. Ask for an A-1 line tap. To do the job right you need guages. The low side pressure should not exceed 5 PSI. Thats all the smart pills I have. The gauges will have 3 hoses. Blue(low side)red(high side)yellow(freon). Put your blue hose on the A-1 tap, connect your freon to the yellow hose, and put the red hose on the vacuum pump. Open all the valves on the gauges and turn on the vacuum pump.(Leave the freon closed). After 30 minutes close all valves and shut down vacuum pump. If the vacuum holds, open the freon can and crack open the blue hose, let the freon go in slowly till it equalizes. Bubble test for leaks at the patch. Plug in the ice box and watch the guage drop. The needle on the blue gauge should be close to 5 PSI for a correct charge (over charging will choke down the compressor,not good). Remember the ice box only holds 4 ounces! That is one third of a 12 ounce can. Weigh it in if you want to be exact. Check for leaks. If all goes well it will be good as new.

AC Wont charge after replacing components


whenever the ac system has been opened it should be hooked up to a vacuum pump designed to evacuate the ac system of any foreign debris and oil etc and after should be able to hold a vacuum to show that there are in fact no leaks then if all is ok at this point you can then charge your ac with the proper freon specified for you car when the pressure reaches satisfactory level the ac compressor will then cycle on you should not bypass the low pressure switch

Where is the high pressure connection for the air conditioner


hi! there,
usually located on high side or discharge presure of the compresor, the discharge service valve fitting equiped w/ cup and pin auto valve ,loosen and remove service cap of service valve fitting,.as you remove the service cap no leak should take place due to it has a pin to locked the pressure on the sysrem . the guage manifold has a host and service port at the end of the host,the sevice port has a tip ball inside port when you connect your pressure guage manifold to test the discharge pressure the tip ball of port will push the pin valve service fitting and opening occued on discharge service valve and the pressure gauge activated and you can the operating discharge pressure.

in your case opening of cap then leakage appear maybe the pin valve was mis aligned or distorted,the service valve was repairable it can repair,but you have to evacuate all freon inside the
system.freon leakage is bad for our environment
use evacuating pump and service tank,after the freon evacuated repair service valve there is pin remover to pull out pin valve sometime cup has pin remover or ask on car air service center.the pin valve has screw type spring attachment replace pin valve and recharge the system you can use the previuos freon on service tank evacuated.

Frost on the low side line means the system is overcharged (too much freon).  Look on the tag insided the fridge and it will tell you how much freon it holds.  Usually 4.25-5.50 ounces on average.  The loud noise sounds like you have air in the system.  I would evacuate, from the high side while running, and let it run empty for 5-10 minutes.  Then while running put the valve core back in the high side.  Then unplug the fridge and charge with proper amount of freon thru the high side.  Wait about 5-10 minutes and plug back in.  Normal low side pressure should be 0-3 psi.  This is a good indicator of the proper amount of freon in a good working system.
