What kind of ac coolant does it have 134a or r 12 and where is the low pressure port for the ac located


Depends on the year. Cars in the early 90's used R12. Anything later uses R134a. The size of the charge ports will define the R134a port. An adapter is needed to fit on the charging hose. R12 requires no such adapter. Ther charging label under the hood will tell you what refrigerant is needed too. Since you failed to give enough information on what make and model car you have, a general answer for the location of the low pressure port will be given. On the compressor, the larger diameter hose connection is the low side. Connect there, or look for the drier/accumulator (Large diameter silver container near the firewall). Connect there. You will need to access the AC information label under the hood to determine how much freon to add to the system.

How much freon do you add to an a/c system on a 1995 ford Taurus. The system is completely empty


There should be a sticker under the hood or in the engine compartment that lists the amount of refridgerant required ? It should be 34 ounces

What freon goes in air condition?


This car originally contained R12, if you can find it you can use it. The other option if this has not already happened is you can convert the system from R12 to R134a, which is readily available, all auto part stores carry these kits. R12 AC fitting are threaded and R134a systems have slip on quick connect fittings.

What type of refrig. does the AC use in a 92 dodge caravan


Unless the labels are missing from the car, it will state which type of refrigerant is used. Could be either R12 or R134a. If originally R12, it could have been replaced by R134a with an upgrade kit. The easiest way to tell if the labels are missing, is to look at the valves on the AC system. If they are Schrader valves (same as used on tires), then it is the older R12. If the caps are Red (high pressure side) and blue (low pressure side), then it is R134a. The sale of R12 to non-certified mechanics is illegal in all states as far as I am aware. R134a is available in most states and retro-fit kits are available in most states.

I have done the retro-fit on 2 vehicles with acceptable results. It is recommended to remove all the old R12 with a vacuum pump. Autozone (in my area anyway) rents these.

Good luck if you need and decide to retro-fit yourself.

How to recharge recharge airconditioner


Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle. Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power. Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can. Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood. Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Take care

What kind of refridgerant do you use for the air conditioner


in 93 you could have R12 or R134a ... R12 is now illegal to use for most cars .. so you would have to have your system retrofitted so it can use R134a ... you can see what kind you have by looking under the hood .. there should be a plaque that tells what kind and how much the system holds .. the R134a systems have a special larger filler port and that is easily recognized by anyone familiar with auto air conditioning .. so just a look will tell them ... R134a is known for slow leaks .. its a small molicule so leaks easily .. the compressor will stop when the pressure gets down too low ..thats to prevent damage .. for now anyone can purchase r134a and many people add it themselves but the law specifies that only certified people can do work on air conditioners .. R12 and R134a are not compatable so you cant mix them .. no matter what the only refridgerrant you can use is R134a ..

there should be a label under the hood stating the Type and amount of refrigerant to us, however before charging the system, it should be pulled down to 20-30 inches of vacuum, to remove any moisture that has accumulated in the system. if it will not maintain a vacuum, you have a leak in the system and will be wasting your time and money by charging the system.

Where do you recharge the airconditioning unit on a 98 jeep grand cherokee 4x4 loredo? Need the location of the fill valve. I already have the recharging kit.


Jeep GrandCherokee SUVs manufactured in or before 1995 use R12 refrigerant. You must retrofit these SUVs to accept R134 refrigerant using a retrofit kit available at your local auto parts store before you can recharge the system. In some areas, a license is required to retrofit an air conditioning system. If this is the case in your area, take your Jeep to a professional to retrofit the system.

Instructions:
  1. Step 1 Take your SUV to a mechanic to recover the R12 refrigerant out of the air conditioning system. A license and special equipment are needed to do this. Because R12 refrigerant is expensive, many mechanics will do the job for free.
  2. Step 2 Locate the Low Pressure Side connector port. You will find it on the driver's side of the engine. Remove the blue or yellow cap marked L. You only need to retrofit the system if you see a screw-type connector valve. If you see a quick connect valve, the system already is R134 compatible. Wipe the connector valve off with a clean towel. This ensures that the retrofit connector properly adheres to the valve.
  3. Step 3 Place the long retrofit connector from the automotive retrofit kit onto the Low Pressure Side valve. The retrofit connector has a special adhesive on the threads that will help it adhere to the valve. Screw the connector onto the valve. Tighten the retrofit connector using an adjustable wrench. Place the cap provided in the retrofit kit onto the retrofit connector. This keeps dust out of the system.
  4. Step 4 Follow the air conditioning lines away from the compressor until you see the High Pressure Side port valve. This is located near the Low Pressure Side service port. Remove the red cap and wipe the port off with a towel.
  5. Step 5 Put the shorter adapter onto the port. Twist it using an adjustable wrench until it is securely fastened to the port. Place the red cap from the retrofit kit onto the adaptor.
  6. Step 6 Fill out the Retrofit Identification sticker provided in the retrofit kit using a permanent marker. Remove the protective backing and place it on the interior side of the hood. This lets future owners and service professionals know that the system has been retrofitted.
  7. Step 7 Recharge the air conditioning system. See the related eHow titled "How to Recharge Air Conditioning with Freon in a Jeep Grand Cherokee."
WARINING:
Never try to evacuate the system yourself. A license and special equipment is needed to evacuate the system. Attempting to do this yourself will release refrigerant into the air, which is a federal crime.

Good luck (rated this help).

AC is not working


Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.

I need to know what the refridgerant capacity of the air conditioning system of my 1985 F 150 5.0L.


It should be written on a label under the hood. But if you are using 134A instead of R12 only fill the system 85% of the R12 capacity.
