Where is the AC low pressure port located?
The low side service valve is located in the line that runs from the compressor through the evaporator (firewall) and up to the condensor on the low pressure (suction) side of the system.
How much Freon does a 1997 Chevy truck hold?
The freon capacity of a 97 is ZERO, the REFRIGERANT capacity is 2.25 lbs or 36 oz of r134a. Depending on replacement parts used, that amount can vary quite a bit. I like to charge by temp myself.
What port do I add freon to?
The low-side port, like the name suggests, is lower on the pipes towards the front of the engine. While the low-side port is intended for recharging Freon, the high-side port is used for maintaining an air conditioner's internal pressure.
Do you add refrigerant to the high or low side?
For systems under a vacuum, once the desired vacuum level has been reached, the vacuum pump has been isolated from the system, and no leaks exist, always charge liquid refrigerant in the high side of the system until high- and low-side pressures equalize and liquid stops flowing.
Which AC line is the low side?
The low side, or suction line, will be the line connected to the compressor from the top or higher position. It will be cold to the touch and may be wrapped with insulation. This is where freon enters the compressor as a gas.
How much freon does a Chevy truck hold?
The refrigerant capacity for the Silverado is 29 ounces or 1.8 lbs. if you want to refill the entire system. If the truck also has a back AC, it will take 48 ounces of R134a or 3 lbs.
What side of the AC do you charge?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
How much freon does a 99 Chevy Silverado hold?
The A/C system on the Silverado holds 2.5 lbs. of refrigerant. Each can is 12 oz.
Do I need to add oil when recharging AC?
The best way to ensure the long life of your AC compressor is to ensure that you add adequate oil any time you add refrigerant to your system. If you've discovered a need for more refrigerant in your vehicle, add BlueDevil Red Angel One Shot.
