The 2004 Civic low pressure air conditioning service port can be found on top of the air conditioner compressor. The low pressure port should be labeled as such.
The 2007 Kia Optima OBD 2 port is right under driver side instrument panel near center console
on the low side pessure port of the compressor line
I am assuming you are talking about the A/C. From the compressor, locate the large black hose comming from the A/C compressor. It goes into a small hard line, the valve on this hard line is the low side service port. The hose the comes from the A/C condencer is the high side service port.
The small connector in the a/c line is the low port and the big connector is the high port side ...
The low side service port is located on the suction line at the top of the engine.....
The low pressure service port is on top of the accumulator (the bottle) located on the passenger side of the engine compartment. It is next to the wiper fluid fill bottle near the grille. It is the SMALLER of the A/C service ports. The high port is on the driver's side. It has a big valve on a smaller diameter line. If you are filling with 134A you MUST fill at the low port...the one on the accumulator (bottle).
Port Line was created in 1914.
All of your charging to your ac system is done through your low side port. The low side service port is located in the line that runs from the compressor through the evaporator (firewall) and up the condensor on the low pressure (suction) side of the system. R134a recharge hoses will only fit on the low side service port on all R134a vehicles and R-12 vehicles that have been converted to R134a.
If you are talking about the low side for the AC system. there should be 2 ports. The port that is on the largest diameter line is the low side.
Yes and yes. The orifice tube is between the service ports.
Its in the biggest line trace it from your a/c compressor.
