WHERE DO YOU PUT FREON IN A 1999 DODGE RAM VAN


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.

How hard would it be to add AC to a 2004 Cavalier Ecotec?


NOT HARD TO ADD BUT YOU NEED A MANIFOLD GAUGE SET TO CHECK AC REGERANT LOW SIDE SHOULD BE 32 - 65 HIGH SIDE SHOULD BE 150 - 325 PSI. DONT PUT ANY REFRIGERANT IN AC SYSTEM IF SYSTEM NOT LOW.PROBLEM COULD BE ELSE WHERE COULD HAVE MOISTURE IN THE AC SYSTEM. CONDENSOR COULD BE OVERHEATING COOLING FAN NOT RUNNING OR AC AIR DOOR NOT OPENING.IF AC REFRIGERANT LOW THE LOW CHARGE PORT NEXT TO REAR STRUT TOWER ON PASSENGER SIDE LOOK FOR SMALL REFRIGERANT LINE WITH CAP GOING TO ACCUMULATOR THE THE INTO FIREWALL TO EVAPORATOR THATS YOUR LOW SIDE.GO TO AUTO PARTS STORE BUY AC R-134 RECHARGE KIT AND WHERE SAFETY GLASSES PROTECT EYES.

How do you add refrigerant.


If you follow the lines coming from the A/c compressor, you will find a red cap on one line and a blue cap on the other line. The blue cap is the suction side. Remove the blue cap. You can buy recharge kits at the parts store that have a line and tap included. You just couple the line there, open the valve on the freon can and start the engine. Run the a/c on high. Be careful not to overcharge the system. If the belts start squeeling, that will indicate too much freon in the system and a high presure situation.

Where do i put the R-134a in on a 2002 volvo s60


On the low pressure valve located between the compressor and accumulator. The low pressure port has a black or blue cap covering the recharge valve. Don't worry, you can't connect the hose to any other valve port but the low side, the hose end is different from the high side. The high side has a red cap, and is not a recharge port.

I want to recharge my AC unit. Not sure where the refrigerant is supposed to go


You connect your refill can or system to the low pressure line. Here is the good news. The fitting on the refill kit will only fit the low pressure line connector. They appear as over sized Air fitting. Both High and Low pressure sides will have plastic caps on them but your coupling will only connect to the low pressure side.

What color of the ac pipe do i add the 134a freon to in my car


if you are asking if you add refrigerant to the high side or low side, you add it to the low side. the single recharge hose only connects to the low side, which has a smaller connector than the high side. so you can't make a mistake. if the caps are colored red and blue, the blue would be the low side.

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).

Which hose do I use to recharge my 2001 chevy cavalier


The blue cap is for recharging the a/c on the low pressure side.

Air conditioner


the smaller cap, is where it is refilled at, that is the low side, the container will only fit on one of the openings, if fluid or air sound happens and doesnt stop for the neck on the ac recharge bottle then you are not on the right spot. but normally the caps are set as black and blue, but look for the smaller cap, if they dont look different before you do anything remove the caps, put the openings on the caps back to back to each other and look close you will see a difference in the cap size... the smaller is where you need to conect the recharger up to... my guess would be the cap by the cylinder is the smaller... I dont know unless I could see it... hope this helps...
