SOURCE: cant find the low pressure port to charge a/c on 2000 olds alero

It should be near the compressor on the low side line. It is a huge pain to get to. Feel along the line, and you should come to the fitting.

How do remove the pressure ,before you add r34 cooler


you never work from the high pressure side of an a/c system. EPA requires it to be recycled, freon is removed using a vacuum tool on the low port until the system holds vacuum for 5 minutes. Then the recycler is removed and freon is added. You mean R134 right?

Were is the low side port for freon charge on 1997 cutlass supreme so


it is behind the engine , at the right down on an ac line.it should have a plastic cap which unscrews, if it is missing there will be a fitting which will fit your ac fill hose. it is best to have a long hose with a shut off valve,as at this location,taking off the hose after filling,is tough as it gets hot back there and if you need to add more than 1 can, you will lose r34 as you try to change cans without unhooking at the port,which is now hot, and is hard to hook up.

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

Where is the low pressure port to fill ac


The low pressure port should be on the Accumulator, that's the silver cylinder that has the low side A/C line going in to it. You'll see the valve on the cylinder for you to add the R134a, do not aver fill the system. Safest way is to open and close the refill valve and let the A/C run for 2 min and see who cold the system is getting adding little at a time. To much R134a in the system will also give you poor A/C performance, to high of pressure in the system will shut down the compressor also.
Thank you for using fixya and when you think the air coming out of the vent is cold enough, stop charging the system.

AC was blowing cold. Now only warm air comes out.


May just need to be recharged, if r34 is too low, ac will not kick in, Wal-mart sells recharge kits and cans of r34 (insctructions are on kit)...expect to pay around $50 total if you do it yourself. If that doesn't work you may have to replace the AC compressor.

1997 Dodge Caravan puts out warm air


Your car uses R-134A, readily available at most auto parts stores. Best bet is to get a refill kit that includes the refill hose (get one with a pressure gauge attached if possible to ensure you don't overfill the system). Recharging is pretty straight forward. Turn the car on with the AC on HIGH, locate the low side AC line (will have a screw on cap). Attach the refrigerant to the hose but don't puncture the can until the other end of the hose is attached to the low side valve. Once both ends are attached, turn the screw on the hose to puncture the can of refrigerant; the car should suction the refrigerant out of the can. Disconnect the hose when the can's empty and check the vents on the AC. If its cold and frost develops on the AC lines under the hood, you're good to go. Best of luck and post back with any questions.

Low-pressure port I need identification


Basic AC system consists of Compressor pump (on engine), Condenser (front grill with radiator) and Evaporator (Firewall). Pump has two ports output (high pressure) and return (low pressure). Follow lines from pump. High side is usually between pump and condenser. Follow lines and find second port this will be low side (refill) port. Paint or replace port caps (red high, blue low). Also, refrigerant in system determines port size (R12 or R34).

How do I add coolant to the air conditioning system of my 2001 Hyundai Elantra?


You need to locate the low port on the AC.

You recharge the AC connecting to the low port.

You find the AC low pressure at the top of the compressor. Near the compressor you find two ports, the high port and low port.
You can follow the compressor line to reach the port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports , often covered with plastic caps. Only one of the pipes will be cold, the line that is cold will lead you to the low port.
