Please visit my BIO page for a link to my Saturn help site. under cooling and a/c you will find a visual reference as to which connector is the low pressure port
The 2001 Saturn L200 low pressure port can be found on the air conditioning compressor. The low pressure port will be closest to the front of the engine compartment.
Larger hose from a/c compressor may be near the drier on the passenger side firewall
iam look for my low pressure point on ford bronco 95
The low pressure port on a Saturn I200 is attached to the oil filter, which is directly below the vehicle's engine. The pressure port is directly attached to the fuel rail, and just above the fuel injectors.
Under the hood
The low pressure port on a 1996 Oldsmobile Cutlass is between the compressor and the firewall. It is on the larger hose attached to the compressor.
high pressure to low pressure
At low pressure the boiling point is lowered and inverse.
At low pressure the boiling point is lowered and inverse.
The larger hose is low pressure
At low pressure, less energy is required for molecules to escape the liquid phase to become gaseous. Conversely, at high pressure, the boiling point is increased.
On the line right at the compressor.
