This is what i got the other day... The gauge is simple to read.. All u need to do is hook it up to the Low port of the ac and check the gauge. Mine was at max so i didn't need to add any, but my intrepid and the Grand prix was almost low..

the hose only fits one of the ports. you fill til the needle of the gauge is on the high side of the green area

I have done driveway repairs on auto ACs for quite a while on both R12 and R134A systems. It'* not for the faint of heart but you can do it yourself and save a ton of money. If you are serious about doing the repairs yourself you need to buy a gauge set such as the one illustrated. This set was on sale at Harbor Freight for about $40 and has the hi and low pressure gauges, the hoses needed and the quick connect adapters for R134A systems. The main danger in doing it yourself in overcharging the system. Too much refrigerant in the system will shorten the life of the compressor seals and lead to compressor failure. The only way to know for sure how much refrigerant is in the system is by reading the pressures indicated on the gauges. This gauge set came with basic instructions for use. You also need vehicle specific data from the vehicle'* A/C performance table. The table I have attached is from the service manual I have for the 2002 SSEi I owned before my '05 GXP and should work because the refrigerant charge of 2.2 lbs is the same for both vehicles. It shows what the hi/lo side readings should be for specific air temperature and humidity ranges because both will affect the pressure readings obtained.

Poor AC performance that happens over time usually indicates loss of refrigerant due to a leak. Leaks can occur at the valves on the service ports or at the o-ring seals where the hoses connect to other fixtures. My experience has been that if the leak is gradual a can of the stop-leak may help. It is easy to use and can be put in the system at the same time you are topping off with fresh R134A.

I know this is a lot to digest but if you have the tools and are willing to do the work you can fix many auto A/C problems yourself and save a lot of cash.

Good luck!

Hi guys,

I have charged the system with 1 pound of 134A. The pressure is a little low, but the results are great. I need to get another can to top it off.

You guys are the best!!! I wish I had thought to do this earlier in the diagnosis of the problem... It seems that several of us GXP owners needed the same advice.

Thanks again!
Jeff R
