R134a recharger nozzle won't fit on low pressure service port.

On my 2004 Pontiac Grand Am, a standard R134a recharger (identical to the one's I use on both my Chevy trucks) will not fit over the low pressure service port. It seems as if the port is about an eigth of an inch too large for the nozzle on the recharger. What's the deal?

The low pressure port on the 2003 grand am is actually behind the engine, near the firewall on the passenger side. Good luck getting your hose down there though, I ended up buying an extension hose.

The r-134a service ports on todays cars are industry standard sizes. the high side port is slightly larger than the low side so you can not hook them up in reverse.make sure your not trying to hook up to the high side port. low side ports are usually located on or near the drier. or in the larger diameter a/c line going to evaporator.

It might be because you are using a r12 retro fit kit. make sure its a r134a recharge kit only

I am trying to put R134A in my car, and I wanted to make sure I put it in the low side service port, but I am having problems figuring out which one is the low side service port


The R134A connection hose will only fit on the low side service port. The high side port is bigger and will not fit that hose.

I want to recharge the a/c of my 2004 Rainier, but do not know where the low pressure port is and the caps are not marked with L or H. Help! Thank you.


The good news is a that vehicle has R134A which means the quick release from your refill can will only fit the low pressure side which is normally a little higher than the High. Unlike the old R22 systems the Low and High pressure connections are slightly different in size.

Can i recharge the air conditioning in my 2001 pontiac grand am se 2.4L myself


yes you can! get an r134a hose and 2 or 3 cans of r134a refrigerant. Find the low side port which has a black or blue cap on it (unless it got thrown away) and use the 'quick connector' while the can is screwed on to the other side of the hose.

You can get a recharge kit for maybe $35 at walmart, which has 1 can of freon which might be all you need to get the cold back into your a/c system.

Make sure that the compressor turns and spins with the belt, and also that the fan turns on at the radiator when you put the a/c on high fan and the coolest setting.

The pressure should range anywhere from 25 to 45 psi when you do this procedure, and if the compressor is not turning the pressure should be 75 to 100 psi on a hot day.

Hope this helps!

I'm looking for the place to recharge my air conditioner on my 1993 Pontiac Grand Prix


being a 1993, it probably uses r-12 refrigerant which is baned by the epa and you probably have to be license to purchase it. best to get it serviced by a qualified tech. it is possible that the system is 134a, in which case the port will be a quick disconnect fitting on the low pressure side. the fitting for the low pressure is between the accumulator/dryer and the condenser. also the low pressure fitting is smaller the the high side. in either case if you have no experience, it's best to consult a set of instructions

Where is the low side service port on a 2003 grand am (6cyl)


If your talking about the low side sevice port to charge your ac, its easy to find. With your recharge kit, it comes with a nozzle to attach to this lowside port. Each port, (lowside and highside), are different diameters. The charging nozzle will ONLY fit onto the lowside port. Just run the length of your ac lines from the compressor and trace them back to the firewall. You should find both ports before you hit the firewall.
