Where is the high side service port?
Locate the high side port on the line that goes from the compressor to the condenser. The high side port will have a 16 mm quick-disconnect valve fitting with a red cap on vehicles with R134a, or a 3/8-inch threaded valve fitting on vehicles with R12.
Will freon leak without cap?
The cap doesn’t do anything to prevent a refrigerant leak, but I wouldn’t drive around without it as it does keep keep dust/grit/water out of the port which can cause other issues and complicate future service.
Where is the freon low pressure?
The low-pressure port will be between the accumulator– located on the passenger side of the firewall–and the compressor. The high-pressure port is located on the line between the condenser–located in front of the radiator–and the evaporator on the firewall.
Where is the low side on a refrigerator compressor?
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.
Where is the low pressure side of the air conditioning system?
Where is the low pressure switch for AC?
Your AC pressure switches are located on both the high and low sides of the unit. These switches monitor and check the pressure of the refrigerant on both sides of the system, with separate switches for both the high side and the low side, which both serve to prevent pressure issues causing damage to the compressor.
What is the high pressure port for AC?
The high side service port is a fitting that provides access to the high pressure side of the AC system and the low side service port is a fitting that provides access to the low pressure side of the AC system.
