Where is the low pressure side AC port located on 2002 ford expedition 5.4L?
The low side service port is located on the receiver-drier or
accumulator cannister that is mounted on the right side (passenger
side), back of the engine compartment and near the fire wall. If
you look behind the battery (firewall, not fender) and under the
block of wires on the the L-shaped metal bracket mounted on the
firewall, that is where you will find it (should have a grey or
black cap). Good Luck!
