No, that's not enough information by itself. If you also knew the volume
of the section at each pressure, then you might have a shot at it.
It is not 1 guage, it is a dual guage that measures high and low side pressures that are used in conjuction with the indoor and outdoor temp, unit size, and blower capacity to determine if you have the correct amount of refrigerant in your system.
The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.
You will definitely lose all of your Freon when you replace the high pressure switch. Once the high pressure switch is loosen the Freon will begin to access the system.
Only after you have put a set of gauges on the a/c system to read both the high and low side pressure readings then you can determine if you need to add freon and oil to the system. If you just add freon and oil because the a/c system is not as cold as it once was it could still be full but might have something else wrong with it. The one thing that you don't want to do is buy one of the do it yourself kits and overcharge the system, this could lead to an expensive repair due to overcharging the a/c system..........
You can add Freon to your 1999 Chevy cooling system through the low pressure port. Connect your Freon bottle to the low pressure port and release the Freon into the system.
Connect the pressure gauge to the high pressure port. Discharge your Freon into the low pressure port. Stop the Freon discharge when the Freon engage reaches the appropriate level.
You put Freon in a 1994 Jeep Cherokee XJ through the low pressure feed to the air compressor. You will want to look for the hose with the green cap to determine you have the right location.
what is the pressure in the gauge with outside 90 degree temperature with freon 22
You can purchase the KIT which usually has a small gage and a special hose that will ONLY fit on the LOW side pressure fitting and the instructions of which tell you how to read the gage in order to determine how MUCH FREON to add to the system.
30 pounds. Is the net weight of the product in a container in it`s liquid state. The vapor pressure within the container will vary according to the temperature of the container. But the net weight is 30 lbs, much like having a propane cylinder refilled.
An ounce. Refrigerant is measured by weight, not volume.
You can put Freon into your 1997 Nissan Pathfinder from the low pressure port. Connect the Freon bottle to the port. Release the Freon into the air conditioning system.
