* 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.

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.

ft. lbs. (14 N.m).
4) Measure air gap between clutch plate and pulley assembly
in several areas. Air gap should be 0.016-0.031" (0.41-0.79 mm). If
air gap is not within specification, adjust shim thickness as
necessary. If air gap is not consistent around clutch plate, lightly
pry up or tap down on clutch plate to make corrections. To complete
installation, reverse removal procedure. Ensure A/C system operates
properly.
5) After completing compressor clutch installation, start
engine. Set A/C-heater control to recirculated air mode and high

MOTORIST ASSURANCE PROGRAM (MAP)
OVERVIEW
The Motorist Assurance Program is the consumer outreach
effort of the Automotive Maintenance and Repair Association, Inc.
(AMRA). Participation in the Motorist Assurance Program is drawn from
retailers, suppliers, independent repair facilities, vehicle
manufacturers and industry associations.
Our organization's mission is to strengthen the relationship
between the consumer and the auto repair industry. We produce
materials that give motorists the information and encouragement to
take greater responsibility for their vehicles-through proper,
manufacturer-recommended, maintenance. We encourage participating
service and repair shops (including franchisees and dealers) to adopt
(1) a Pledge of Assurance to their Customers and (2) the Motorist
Assurance Program Standards of Service. All participating service
providers have agreed to subscribe to this Pledge and to adhere to the
promulgated Standards of Service demonstrating to their customers that
they are serious about customer satisfaction.
These Standards of Service require that an inspection of the
vehicle's (problem) system be made and the results communicated to the\
customer according to industry standards. Given that the industry did
not have such standards, the Motorist Assurance Program successfully
promulgated industry inspection communication standards in 1994-95 for
the following systems: Exhaust, Brakes, ABS, Steering and Suspension,
Engine Maintenance and Performance, HVAC, and Electrical Systems.
Further, revisions to all of these inspection communication standards
