Pressure gauges. In a home or car AC there is small pipe and a large pipe going to the compressor unit outside or in the engine compartment. The large pipe should be cold and "sweating" ( dripping water).
v have to check the blower motor,ac pipe lines and cluster assembly
To recharge the AC on the S430, someone should plug in the refrigerant kit on the thin pipe. The service port allows someone to check the state of the pressure gauge.Ê
It is the black pipe sticking out under the AC accumulator (large cylindrical object) bracket on the passenger side of the firewall.It is the black pipe sticking out under the AC accumulator (large cylindrical object) bracket on the passenger side of the firewall.
Freon is added through the ac low pressure port. The port is located on the aluminum pipe on the ac line.
Because of the difference in temperature of the pipe (or the water in the pipe) and the air surrounding it. You could try a foam insulation from your hardware store.
Freon is added in the low pressure port of the ac system. It is on an aluminum pipe on the passengers side, close to the ac drier.
The Freon low pressure port is located on the passenger side of the engine near the back. It is made into an aluminum pipe connected to the ac hoses.
there is a pipe running along side of inner wing on the Drivers side this is the ac pipe, halfway along toward windscreen there is a valve on top of pipe usually with a green cap on it, that is where freon goes..
The recharge port is on the larger AC pipe
The port is on the cold ac pipe located toward the front of the engine on the manifold side. It is usually marked with a blue dust cap.
