REFRIGERANT OILS
* PLEASE READ THIS FIRST *
NOTE: Use ONLY the specified oil for the A/C system or compressor.
Always check the underhood A/C specification label or A/C
compressor label before adding refrigerant oil to A/C
compressor/system.
NOTE: For compressor applications, see COMPRESSOR APPLICATIONS &
BODY DESIGNATIONS. DO NOT exceed A/C system refrigerant oil
capacity when servicing system. See CAPACITIES.

Contour, Cougar, Escort, Mustang, Mystique, Tracer and Windstar,
drill two 1/2" holes in bottom of old accumulator, and drain. On
all models, add the same amount of oil drained plus 2 ounces of
refrigerant oil to new accumulator.
(2) - Add refrigerant oil following replacement of other system
components such as hoses, fixed orifice tube, A/C clutch cycling
switch, A/C compressor pressure relief valve, system pressure
cut-off switch, or service valve, compressor shaft seal, "O"
ring or hose leaks.
( 3) - If all lines have been replaced.

HARRISON HD6/HT6, HD6/HR-6HE 6-CYL., V5 5-CYL. & V7 7-CYL.
NOTE: Replacement compressor may be shipped with 8-9 ounces of
refrigerant oil. Drain shipping refrigerant oil into a clean
container and retain for use.
1) If possible, operate system for several minutes to
stabilize system. Turn engine off. Discharge A/C system, using
approved refrigerant recovery/recycling equipment. Remove A/C
compressor. Drain and measure refrigerant oil from old compressor
through suction and discharge ports, and drain plug.
2) If no compressor oil leaks exist, and more than one ounce
is drained, add amount drained from old compressor. If less than one
ounce is drained from old compressor, add 2 ounces of refrigerant oil.
3) When replacing other A/C components, add specified amount
of refrigerant oil to component. See HD6/HT6, HD6/HR-6HE, V5 & V7
COMPONENT REFRIGERANT OIL CAPACITIES table. Install compressor drain
plug and compressor. Evacuate and charge system. Perform leak test.
Ensure A/C system is operating properly.
NOTE: Approximately 3 ounces of refrigerant oil, suspended in
refrigerant, will be lost due to a large, abrupt leak. When
replacing a faulty A/C component, add amount of oil specified
for component plus 3 ounces to compensate for oil loss. If
oil cannot easily be added to component, add it to
accumulator.
