There is a blue cap connection on the underside of the compressor. You have to get under the car to locate and service it

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.

Along the condensor lines, you will find 2 ports that should have screwed on black caps, you will then remove the cap. Dependant on the year, you may need to upgrade the system R-12, vs R-134a; and recharge kits are available at various locations depending where you live. Also, the AC system is charged based on pounds, so be extra careful when attempting a new charge. Some vehicles only require 2 lbs.

Where do i put in th recharge coolent for the

There are 2 service valves on this modl of escort, one located on the right hand side of the radiator as you face the engine and one located next to the accumulator by the firewall on the passengers side. The high pressuresde is the one to the right of the radiator, and the suction side is close to the accumulator on the passengers side. Put freon in the passenger side next to the accumulator. The high pressure side is strictly for checking the head pressure, do not try to put freon in that side. Look for around 40 psi on the low side .. There are more technical ways to do this but this will get you into the right area. If you don't have a guage, add freon until the fan clutch quits cycling at fast idle.

Where is my lo intake valave for my a/c on my 98 dodge grand caravan

The low side fitting is on the passenger side of the car, near the compressor and the headlight area, close to the drive belt, about 12" away from the radiator. Locate the black screw dust a cap, looks similiar to a valve stem cap on your tire valves. The high side connector is located in the engine compartment, passenger side, near the fender well back towards the alternator and very close to the drive belt. The high side fitting is much harder to find than the low side, the low side is in the open. The fitting you have for adding R134a from the recharge kit will not fit on the high side. The high side fitting is smaller than the low side fitting. Thank goddness for that for if you were capable of putting the fron can onto the high pressure line, it would develope so much pressure from the high side, it would or could explode in your presence.
Please be aware that you need to wear protective eye and hand gear when working on an a/c system(freon can blind you if sprayed directly in your eyes and can cause frost bite when over exposure to your skin.
Happy Motoring!!

I have a 2004 ford focus, and i need to add freon. But, the owners manual doesn't say where to add it. I even looked, and there isnt anything obvious under the hood like the blue cap on my cavalier. Can...

This is really a fix for a shop, but what you are looking for is a fitting that looks like the air valve on a tire... but be careful, there is also a similar fitting on your fuel rail. The fitting you are looking for should be on the A/C line near your condenser (looks like another radiator) or near the dryer (which looks like a tall can).

your system is a 134a it is not freon based. the lowside is the bigger port and usually has a large black or blue cap on it it should be located near the a/c compressor on the driver side where the line goes to the condensor. your high side should be on the passenger side near the dryer it will be the smaller port and have either a black or red cap. the ,low side pressure should be 35 psi and the high side should be 150 psi. please rate this.....thanks

#1 you will need r134a freon. #2 the low side service port is located right at the firewall where tha line goes to the evaporator. #3 if wou bought a can of 134a freon with a hose that will hook to it, it will work. all service fittings for 134a freon are the same even though the high side and the low side will always differ
