Wehere is the valve to refill the ac - 1995 Pontiac Grand Am

Posted by on

  • Greg McCarthy Aug 05, 2010

    There should be 2 black caps on an aluminum line for the a/c line.Remove the cap closest to the belt system.This is the high side where the evaporator and compressor is.Fill the a/c with the engine running,a/c on,at one quarter can intervals.When it is cold enough stop because overpressurizing the system can cause big damage.If you lose coldness within a couple of days,there is probably a leak.If you try to fill it on the wrong side,it will not hurt the system,it simply won't come out.Good luck!

Do I have to change my compressor? This is my 3rd freon refill. A 230E '99 MB.


no you do not need a new compressor; take your car to an ac shop and, make sure they change the fill valves (they look like oversized tire valves inside the compressor where the freon lines attach (after time the o-rings fail in these and, they leak refrigerant; obviously your dealer has an incompetent ac mechanic or. these should have been inspected and, if having failed: replaced.

Hi Andreas, The valves for evacuation and refilling the ac are the same. To drain the system an evacuation pump should be connected to the low pressure and high pressure valves. The valves are situated in the engine compartment, the high pressure has a red valve cover and the low pressure black. You will easily find the valves by looking along the air conditioning plumbing.

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.

Low pressure ac port


Two ports under hood for ac, use the one closest to the fire wall. Refill valve will only hook up to this one. Use a gauge on refill can so you dont over fill system and blow a o ring

Trying to find ac service ports on 03 lincoln ls


the AC service ports are capped with either blue or black caps... and being yours uses R134A, on the container the valve will only fit on the right valve under the hood... the smaller valve is the low side, that is the one you want if you are refilling... the high side will have a larger valve and the container will not fit it... YOU WANT THE SMALL VALVE... NOT THE LARGER VALVE... hope this helps you out...

Is the A/C low side port at the firewall, passenger side?


the low side ac valve, should have a blue cap. and is the smaller of the 2 valves. that smaller one is what you would need to use to refill the system..if you are planning on refilling the ac, make sure the bottle you get to refill with is the right fluid... some earlier cars still run on r12, and some run on r134a. if you are going to fill it, have the car running and then check the pressure before you add any fluid cause you will mess the system up adding to much... hope this helps you..

please rate as fixed if this helps you.

The low pressure service gauge port valve is located on the evaporator to accumulator/drier suction line.
