Removal
1) Remove drive belt pulley (if equipped). Hold clutch plate\
using Pliers (MB991367) and Bolts (MB991386). Use a ratchet and sock\
et
to remove clutch hub nut.
2) Remove clutch plate. See Fig. 3 or 4. Remove snap ring
with internal snap ring pliers. Remove clutch hub (rotor). Remove snap\
ring and clutch coil.
3) Using an awl, remove bearing cover and retainer. Using
Bearing Remover (MB991456), engage bearing grooves. Place base of
bearing remover over remover arms and tighten nut.
4) Tighten bearing remover bolt to withdraw bearing from
compressor. Engage grooves of Shaft Seal Remover/Installer (MB991458)
and pull straight up on shaft seal.
Installation
1) To install shaft seal, ensure front housing is free of
foreign objects. Lubricate Shaft Seal Protector (MB991459) and place
over compressor shaft. Lubricate shaft seal and install using shaft
seal remover/installer. Remove shaft seal protector.
2) Using a 21-mm socket or Drift (MB991301), carefully press\
bearing onto compressor shaft. Install clutch coil so that alignment
pin is engaged. Install clutch coil snap ring with tapered side facing
out.
3) Align armature plate with crankshaft spline. Tighten shaft
nut to 12 ft. lbs. (16 N.m). Using feeler gauge, ensure air gap
between pressure plate and pulley is 0.02-0.03" (0.5-0.8 mm) on
Diamante and 0.016-0.024" (0.4-0.6 mm) on all other models. If air gap\
is incorrect, add or remove shim(s) as necessary.

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

DESCRIPTION
Slight variations exist among manual A/C-heater systems used.
On Montero, a Nippondenso 10-cylinder compressor is used. Cycling of
compressor clutch is controlled by an automatic A/C Control Unit
(ACCU).
Compressors will only operate within normal temperatures and
pressures set for each model. An electric condenser fan operates
whenever A/C system is operating. System components may vary depending
upon model. Systems may include an ACCU, fan switch, evaporator,
temperature sensor, dual-pressure switch, engine coolant temperature
switch, compressor, condenser, receiver-drier and various pipes and
hoses.
OPERATION
A/C CONTROL UNIT (ACCU)
ACCU controls cycling of compressor clutch based on
information received from air thermosensor and air inlet sensor, dual-
pressure switch, A/C switch and A/C engine coolant temperature switch.
ACCU is attached to top of evaporator housing.

ADJUSTMENTS
NOTE: For adjustment procedures, see HEATER SYSTEM article.
TROUBLE SHOOTING
NO COOLING
1) Ensure compressor clutch is operating. If compressor
clutch is operating, go to next step. If compressor clutch is not
operating, check fuses and A/C switch. Check dual-pressure switch.
Check air inlet sensor and air thermosensor. Check A/C compressor
relay. Check A/C compressor clutch coil. Check A/C control unit.
2) Ensure system is properly charged with correct amount of
refrigerant. Evacuate and charge system as necessary. Ensure receiver-
drier is not clogged. Check compressor belt for proper tension. Check
for clogged expansion valve. Check compressor operation. Repair or
replace components as necessary.
INSUFFICIENT AIRFLOW
Check for air leakage at air duct joint. Check for frost on
evaporator. Ensure blower motor is operating properly. Check for
obstructed air intake.
INSUFFICIENT COOLING
Ensure system is properly charged with correct amount of
refrigerant and free of air and moisture. Evacuate and charge system
as necessary. Ensure receiver-drier is not clogged. Ensure sufficient
airflow through condenser exists. Check compressor belt for proper
tension. Check compressor operation. Repair or replace compressor as
necessary. Check for clogged expansion valve. Replace expansion valve
as necessary. Check A/C compressor clutch coil.
INTERMITTENT COOL AIR
Check for air or moisture in system. Evacuate and charge
system as necessary. Check for expansion valve malfunction. Replace
expansion valve if necessary. Check compressor belt for proper
tension.
TESTING
* PLEASE READ THIS FIRST *
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all SERVICE PRECAUTIONS and DISABLING &
ACTIVATING AIR BAG SYSTEM procedures in AIR BAG RESTRAINT
SYSTEM article.
NOTE: For testing procedures not covered in this article, see
HEATER SYSTEM article.
A/C SYSTEM PERFORMANCE
1) Park vehicle out of direct sunlight. Install A/C gauge
set. Start engine and allow it to idle at 1000 RPM. Turn A/C on. Set
A/C controls to recirculated air, panel (vent) mode and full cold

Removal & Installation
1) Discharge A/C system, using approved refrigerant
recovery/recycling equipment. Remove front grille and grille brackets.
Remove hood latch bracket mounting bolt. Remove hood latch brace.
Remove A/T oil cooler and engine oil cooler mounting bolts and
brackets.
2) Remove receiver bracket and receiver. Remove condenser fan
motor. Disconnect pressure lines from condenser. Remove condenser
mounting bolts. Lift condenser from vehicle. To install, reverse
removal procedure. See Fig. 11. If replacing condenser, add 1.4 ounces
of refrigerant oil to new condenser.
