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.

Other Means Of Identification
Refrigerant R-134a, when viewed through a sight glass, may
have a "milky" appearance due to the mixture of refrigerant and
lubricating oil. As the refrigerant and oil DO NOT exhibit a "clear"
sight glass on a properly charged A/C system, most R-134a systems have
no sight glass.
REFRIGERANT OILS
NOTE: Use ONLY the specified oil for the appropriate system or A/C
compressor. Always check vehicle underhood A/C specification
label or A/C compressor label before adding refrigerant oil
to A/C compressor/system. See Figs. 2 and 3. Always use
refrigerant oil specified on vehicle underhood A/C
specification label if different from the following list.
Refrigerant R-12 based systems use mineral oil, while R-134a
systems use Polyalkylene Glycol (PAG) oils. Using a mineral oil based
lubricant with R-134a will result in A/C compressor failure due to
lack of proper lubrication. The following R-134a refrigerant oils are
currently specified:
Use DENSO/ND-Oil 8 refrigerant oil on Nippondenso
compressors. Use SUN PAG 56 refrigerant oil on Sanden compressors.
NOTE: PAG oils absorb moisture very rapidly, 2.3-5.6 percent by
weight, as compared to a mineral oil absorption rate of
0.005 percent by weight.
SERVICE EQUIPMENT
A/C systems using R-134a refrigerant and PAG lubricants
cannot use R-12 refrigerant or mineral oil lubricants. R-134a
refrigerant is NOT compatible or interchangeable with R-12
refrigerant. Separate sets of hoses, manifold gauge sets and
recovery/recycling equipment are required to service the different
systems. This is necessary to avoid cross-contaminating and damaging
A/C system. A single set of A/C service equipment cannot be cleaned
thoroughly enough to be used with both types of refrigerant.
All equipment used to service A/C systems using R-134a must
be U.L. listed and certified to meet SAE standard J2210. The service
hoses on the manifold gauge set must have manual (turn wheel) or
automatic back-flow valves at the service port connector ends. This
will prevent refrigerant from being released into the atmosphere.
For identification purposes, R-134a service hoses must have a
Black stripe along its length and be clearly labeled SAE J2196/R-134a.
The low pressure test hose is Blue with a Black stripe. The high
pressure test hose is Red with a Black stripe, and the center test
hose is Yellow with a Black stripe.
R-134a manifold gauge sets can be identified by one or all of
the following: Labeled FOR USE WITH R-134a on set, labeled HFC-134a or
R-134a on gauge face, or by a Light Blue color on gauge face. In
addition, pressure/temperature scales on R-134a gauge sets are
different from R-12 manifold gauge sets.
SYSTEM SERVICE VALVES
SCHRADER-TYPE VALVES
NOTE: Although similar in construction and operation to a tire
valve, NEVER replace a Schrader-type valve with a tire valve.

Schrader valve is similar in construction and operation to a
tire valve. When a test gauge hose with built-in valve core depressor
is attached, Schrader stem is pushed inward to the open position and
allows system pressure to reach gauge.
If test hose does not have a built-in core depressor, an
adapter must be used. Never attach hose or adapter to Schrader valve
unless it is first connected to manifold gauge set.
Refrigerant R-12 Schrader-type valve cores have TV5 thread
size. Refrigerant R-134a Schrader-type valve cores use M6 (Metric)
threads. See Fig. 1.

REFRIGERANT RECOVERY/RECYCLING
Refrigerant recovery/recycling equipment is used to remove
refrigerant from vehicle's A/C system without polluting atmosphere. To
remove and recycle refrigerant, connect the recovery/recycling
equipment and following the equipment manufacturer's instructions.
Removed refrigerant is filtered, dried and stored in a tank
within the recovery/recycling equipment until it is ready to be pumped
back into vehicle A/C system. With refrigerant stored in the
recovery/recycling equipment, A/C system can be opened without
polluting atmosphere.
NOTE: Separate sets of hoses, gauges and refrigerant
recovery/recycling equipment MUST be used for R-12 and
R-134a based systems. DO NOT mix R-12 and R-134a
refrigerants, as their refrigerant oils and desiccants are
not compatible. It is NOT possible to clean equipment
thoroughly enough to prevent cross-contamination of A/C
systems. On systems with R-134a refrigerant, use
Polyalkylene Glycol (PAG) wax-free refrigerant oil.

WHEEL & TIRE SPECIFICATIONS
Tire specifications are imprinted on the tire side wall. The
recommended cold tire inflation pressures are listed on a label
attached to the rear face of the driver's door. These pressures
provide the best combination of ride comfort, tire wear and stability
under normal conditions.
CAUTION: DO NOT mix tires of different design such as radial ply
with bias or bias-belted tires. Mixing tire types will
adversely affect road handling and may lead to loss of
vehicle control. When using snow tires, they must be used
in set of four for maneuverability and safety. DO NOT use
tire chains on front wheels.
