How do I find the low side port?

How do I find the low side port?

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.

Which line is low side on AC?

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.

What components are on the low side of an AC system?

The low side of a refrigeration system usually houses the evaporator, suction line, and any accessory components located within the suction line. Accessory components can include evaporator pressure regulator valves, suction filters and driers, crankcase pressure regulator valves, and suction accumulators.

Can you fill AC on high side?

The LOW side fitting is usually located on the suction hose or line that goes from the accumulator to the compressor. The HIGH side fitting is located on the line that goes from the compressor to the condenser.

Where is the low side of the a / C port?

The A/C is not working and I want to check the pressure on both the low and high side, but can not find the low side port. There are 2 ports (both a large and small size) on the metal line running from the evaporator to the condenser, but I can’t find a port between the compressor and the evaporator, which should be the low side.

Where is the low side Freon recharge port?

There are 2 ports (both a large and small size) on the metal line running from the evaporator to the condenser, but I can’t find a port between the compressor and the evaporator, which should be the low side. Please let me know where to low side port is. Re: A/C freon recharge – low side port?

What should high side and low side pressure be?

If it’s 100 degrees then the high side pressure should be between 220 and 250 psi. Start by targeting the lower end of that, it’s easier to add than remove. When you stop adding your low side should be between 30 and 40 psi. Re: A/C freon recharge – low side port?

Where is the low pressure port on a Silverado Sierra?

I have a 2001 silverado 5.3 and just added some 134 and the low pressure port was the smaller one and was located closest to the cab the high pressure port was closest to the front of the truck and larger in size. My truck was blowing cool but not cold in heat. I added 1/2 a can of 134 and it’s blowing nice and cold now.
