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.

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.
