A. Overview of cooling fan and A/C compressor
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions. The water pump draws the coolant from the radiator. The coolant then
circulates through water jackets in the engine block, the intake manifold, and the cylinder head.
When the coolant reaches the operating temperature of the thermostat, the thermostat opens.
The coolant then goes back to the radiator where it cools. The heat from automatic transmission
is also cooled down through the radiator by circulating the oil through the oil pump. ECU controls
the electric cooling fans with three cooling fan relays to improve the engine torque and air
conditioning performance.
For detailed information, refer to Chapter "Air Conditioning System".

2. DESCRIPTION AND OPERATION
1) General Description
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions.
When the engine is cold, the cooling system cools the engine slowly or not at all. This slow
cooling of the engine allows the engine to warm up quickly.
The cooling system includes a radiator and recovery subsystem, cooling fans, a thermostat and
housing, a water pump, and a water pump drive belt. The timing belt drives the water pump.
All components must function properly for the cooling system to operation. The water pump
draws the coolant from the radiator. The coolant then circulates through water jackets in the
engine block, the intake manifold, and the cylinder head. When the coolant reaches the operating
temperature of the thermostat, the thermostat opens. The coolant then goes back to the radiator
where it cools.
This system directs some coolant through the hoses to the heat core. This provides for heating
and defrosting.
The coolant reservoir is connected to the radiator to recover the coolant displaced by expansion
from the high temperatures. The coolant reservoir maintains the correct coolant level.
The cooling system for this vehicle has no radiator cap or filler neck. The coolant is added to the
cooling system through the coolant reservoir.
2) Radiator
This vehicle has a lightweight tube-and-fin aluminum radiator. Plastic tanks are mounted on the
upper and the lower sides of the radiator core.
On vehicles equipped with automatic transaxles, the transaxle fluid cooler lines run through the
radiator tank.
A radiator drain plug is on this radiator.
To drain the cooling system, open the drain plug.
3) Coolant Reservoir
The coolant reservoir is a transparent plastic reservoir, similar to the windshield washer reservoir.
The coolant reservoir is connected to the radiator by a hose and to the engine cooling system by
another hose.
As the vehicle is driven, the engine coolant heats and expands. The portion of the engine coolant
displaced by this expansion flows from the radiator and the engine into the coolant reservoir. The
air trapped in the radiator and the engine is degassed into the coolant reservoir.
When the engine stops, the engine coolant cools and contracts. The displaced engine coolant is
then drawn back into the radiator and the engine. This keeps the radiator filled with the coolant to
the desired level at all times and increases the cooling efficiency.
Maintain the coolant level between the MIN and MAX marks on the coolant reservoir when the
system is cold.

3. WARNING LIGHTS AND INDICATORS
ESP OFF Indicator
This lamp comes on when pressing
the "ESP OFF" switch or the ESP
system is defective. When the ESP
system is activated, this lamp blinks
and a chime sounds.
Immobilizer Indicator
This indicator comes on when the
ignition key is communicating with
the engine control unit for approx.
0.5 seconds.
Glow Indicator
When the ignition key is turned ON,
this indicator lamp comes on and the
combustion chamber is warmed up.
In the vehicle equipped with direct
injection type engine, this indicator
may come on very shortly or may not
come on.
Fog Lamp / Headlamp
High Beam Indicator
This lamp comes on when
the fog lamp or high beam
headlamp operates to
indicate the operating
status.Engine Oil Pressure Warning Ligh
This lamp comes on if there is any
fault in the engine oil system and
goes off when a certain amount of
time has elapsed after turning ON
the ignition switch.
Door ajar warning
light
This light comes on
when a door or
tailgate is either
opened or not
closed completely.Brake warning light
This warning light comes on
and warning buzzer sounds
when the parking brake is
applied and/or the brake fluid
level is lower than specified
level.Seat belt warning lamp
The seat belt warning light comes on
and the seat belt warning chime
sounds for 6 seconds when the
ignition switch is turned to "ON"
position unless the driver's seat belt is
securely fastened. This reminding
operation stops when the driver
fastens the seat belt.
Engine Coolant Overheat
Warning Light
When the coolant temperature is
abnormally hot (over 120℃), this
warning light blinks and a
warning buzzer sounds at 1 Hz.
