Recharge the air conditioner


Instructions
    • 1Start the recharging process with any left over freon you may still have. Open the Civic's hood and attach the kit to the Civic's low side port. Then, set the kit onto a place in the engine compartment where nothing can move or shift once the engine has been cranked.
    • 2Start the Civic and let the engine run until it reaches its normal operational temperature.

    • 3Turn on the air conditioning to its coldest and hardest-blowing settings. Place a thermometer into one of the Civic's air conditioning vents and monitor how the temperature drops. Once the air conditioning's temperature reaches a level, constant degree, remove the thermometer.
    • 4Open all four doors on the Civic. This will allow any colder air generated to escape, and this will keep the Civic's air conditioning for accidentally cycling off while you recharge the refrigerant levels.
    • 5Turn the recharging kit's valve all the way down and let the refrigerant charge into the Civic's air conditioning periodically, shut the valve and look at the kit's gauge. This will allow you to monitor the recharging process. Allow at least one minute to elapse between refrigerant charges into the system.
    • 6Shut the valve of the canister, once it has become depleted. Disconnect the kit from the low side port.
    • 7Detach the hose, gauge, and valve from the empty canister and attach them to a new canister of refrigerant. Reattach the kit's hose to the Civic's low side port and continue recharging the system, allowing a minute between individual charges. The can itself can potentially grow very cold and hard to hold, even with gloves. Should this happen, wrap the can in a towel warmed in water. Ring out excess water before wrapping the canister.
    • 8Place you thermometer into one of the Civic's air conditioning ducts. Keep an eye on the falling temperature within the Civic's air conditioning system. The system is charged when the temperature hits 40 degrees. Also, within the engine compartment, the Civic's air conditioning aluminum tubing become uniformly cold.
    • 9Shut the recharging kit's valve and remove the kit from the low side port, once the system has been successfully recharged. Shut down the Civic's air conditioning, turn the engine off, and remove your key from the Civic's ignition. Also, shut all the doors

I am trying to put an AC recharge can into my car and can not locate the valve where the cans dispenser is to be connected to complete this...please help


Attach the end of the recharge hose to the low side pressure port on the passenger's side of the engine compartment, near the firewall. Look for the metal coolant lines and follow the lines to locate the low side pressure port. The port is usually covered by a plastic cap. Screw the discharge end of the recharge hose -- the end without the handle/valve -- to the pressure port.
  • Screw the valve end of the recharge hose onto the top of the can of refrigerant. Turn the handle clockwise to pierce the top of the can of refrigerant. Turn the handle counterclockwise to allow the refrigerant to flow into the hose.
  • Start the Cutlass. Turn on the air conditioning to the maximum setting.
  • Turn the can of refrigerant upside down and gently swirl the can. This moves the refrigerant from the can to the hose and into the air conditioning system.
  • Insert a thermometer into the interior of the center air vent and test the temperature of the air coming from the duct. It should be approximately 35 degrees colder than the ambient air temperature.
  • Add more coolant if necessary. If you are using 12-ounce cans, unscrew the first can and screw the hose onto the second can. Turn the handle clockwise to pierce the top of the can, then turn it counterclockwise to allow the refrigerant to flow into the hose. Do not add more than 24 ounces to the system. Take your Cutlass to a service center if you have added more than 24 ounces to the system and there is no difference in the temperature.
  • Turn off the engine of the Cutlass.
  • Turn the handle on the recharge hose clockwise to seal the can of refrigerant of it is not empty. If it is empty, unscrew the can from the hose. Unscrew the discharge end of the hose from the low side pressure port. Place the colored cap over the pressure port.

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.

Air conditioning needs recharged


First, you have to locate the thicker line in the compressor, then follow up until you find the valve to recharge the system, usually is located near by the accumulator bottle.
