Line that goes to compressor is low side line out of compressor is high side
always fill on low side
also r12 hase been band for sevral years and should not be used
if this freon is r-12 conpatible or replacment then your fine
after leak been repaired and system pressurized and vacumed out
start engine put a/c to max blower motor to hi open windows
conect your fill bottle to low side open valve and system will start filling
when freon reach enougt pressure the compressor should start and draw in
the freon if it fails to start you could jump the low pressure swich to help draw in
freon when system has drawned its capacity shut off your bottle and disconect your line to fill
cap off the valve
if compressor fail to start you have another issus could be electrical
take CAUTION doing repairs to a/c system

I need to put freon in my 1992 ford explorer but i can not find the valve for it. Can you help please.


Your 1992 vehicle is probably R12 and not R134a. Since R12 was discontinued due to enviornmental concerns, your system will need to be "retrofitted" to the new 134a refrigerant. I would take it to any auto A/C shop that you trust and have them do the work. they will need to remove all the R12 refrigerant, flush all the oil out, change the service ports, replace the drier/reciever and then recharge. Total cost for this will depend on what area of the country you live in as labor rates are set by the geographic area.

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

Locate a/c high low valves.


The low side should be located on the thing that looks like a can against the firewall. I won't tell you about the high side, this wil just get you hurt.

Have a 1986 F-350 A/C puts out cool air but not cold. Don't know if system is R12 or 134A. Compressor is centr and has 2 threaded black caps with schrader valves for gage connection plus 1 quick disconnect...


in 1986 it is r12 but you can convert to r134 which is a ton cheaper than paying for r12 you need a license to buy r12 r134 is right on the shelf at auto zone they also sell retro fit kits with everything you need to convert your system and they work very well

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).

My ac wont work


Must be Air-Condition System Lines/ Hoses leaking R12 Freon (gas).

MAYBE THE PULLY HUB BEARINGS FAILED OR
DUE TO VERY LOW R12 FREON (GAS ) will not work.
Because there is a switch in the receiver/dryer prevent AC from working when low R12 Freon present, to protect the system & compressor damages.

You must fix the leaks, before recharging it.

They must **** the old (residue) gases from the system & lines / hoses...... & stay in the vacuum pump 30 minutes to proof no more leaks.

Recharge some oil for the old type R12 Freon gas.

Before recharge it to 62-67 psi R12 Freon

See the web site like www.youtube.com/video site to see How they service & repair air-condition system?
Put the question to their search window.

My recharging kit for air conditioner doesn't seem to fit recharge valve on 2004 dodge durango. How can I be sure i am looking at the low prerssure valve?


Newer vehicle come with R134 vs R12. Since the two are not compatible, R134 has larger fittings. AC system has two ports, High and Low. Low is return to AC Compressor and high is output. High port is first following line from compressor to condenser (condenser is at front of vehicle like a second radiator). Keep following line till you find high port (paint cap red). Second port is low (paint cap blue).

How do I recharge the AC freon on my own?


You should have R12 freon in a 1990 but you can put R134 freon into that system the only problem your going to have is the adapter for R12 is different from R134 after you get the adapter you need to put the freon in the low pressure valve not the high pressure, you will know which one because the adapter only fits the low pressure valve which is located on your AC lines under your hood, theres a little cap thats either blue or black you unscrew. You can't buy r12 anymore because its not good for enviorment so buy R134. you can buy at any parts store for like $5 to $10.
