A/C system has a high and low side line. The line you add freon too is the low side. The lines are on the passenger side of the truck under the hood. The larger line is the low side line, follow it from the radiator back toward the fire wall. You will come across a fitting which should have a cap on it, but it may be missing the cap. Thats the low side port.

Simple AC recharge question


Refilling a cars AC system is a specialised job and should not be handled by the owner ,you need a special machine to regas a vehicle where you drain it and measure the amount of gas in the system then add oil and leak dye then regas to the correct weight of gas.Here in europe you cannot buy a can of gas as its classed as a dangerous substance ,only a authorised garage can purchase gas in a 12kg cannister to refill the AC machine and the operator must hold a certificae to use the machine ,so to check out why and what you must take the vehicle to a authorised garage .

Were to put freon in at the fist hook up or second


Your system has R134A Freon. The good news is those two couplings are different sizes. The refill can connector will only connect to the low side which is the proper side to refill the AC System.

Where do i put r134 in my 1999 chevy luminia


You have to locate the Low Pressure line for your AC and connect the refill hose and gauge to that. It will have, in most cases, a black or blue dust cover cap made of plastic on it. The refill kit will only fit the low pressure side as these connectors are different in size.

The ac light starts flashing when i begin to refill the system. I replaced the compressor, dryer, evaporator, expansion valve, and pressure switch that connects to the same piping. It is my understanding...


usually you have to have these ac systems vacumed while refilling, also you could have a bad compressor, even if it is new, friend of mine has this same car, bought new comp from autozone, basically same problem you are having, check with auto parts to see exactally how much comp oil is needed and freon, you may have to much freon in it.

I need to retrofit and recharge my 1988 Dodge Ram Ac.


First, the old R-12 must be completely evacuated fromt the system. R-12 and R-134A do not mix and won't function together. Once you are sure there's no R-12 left in the system, you need to install an R-134A fill valve on the low side AC line. This is where your refill hose will connect to add R-134A. Once the valve is in place you're ready to fill the system. The compressor requires a minimum of 20psi to engage and should not be filled to more than 45psi.

RECHARGING AC SYSTEM

1.Turn the truck on and turn AC on HIGH
2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
4.Insert the other end of the refill hose to the low side valve
5.Puncture the R-134A can with the screw on the refill hose
6.You should feel the system suction the refrigerant out of the can
7.Check for frost on the AC lines and the air blowing inside the truck
8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.

On my 1995 Dodge Ram When I turn the A/C On it dosent seem to kick in and get cold just warm air?


In most cases, the problem is the system is low on refrigerant. The AC compressor requires a minimum of 20psi of refrigerant to turn on. There are refill kits available at the auto parts stores. If doing this yourself, select a kit that includes compressor oil, and a refill hose.

RECHARGING AC SYSTEM

  1. Turn the truck on and turn AC on HIGH
  2. Locate the low side AC line (will have a valve and cap similar to the cap on a tire)
  3. Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet)
  4. Insert the other end of the refill hose to the low side valve
  5. Puncture the R-134A can with the screw on the refill hose
  6. You should feel the system suction the refrigerant out of the can
  7. Check for frost on the AC lines and the air blowing inside the truck
  8. If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective
Hopefully this answers your question and you're able to get your AC working again. Best of luck.
