The cooling fans are mounted behind the radiator in the engine compartment. The electric cooling fans
increase the flow of air across the radiator fins and across the condenser on air conditioned (A/C)-
equipped vehicles.
This helps to speed cooling when the vehicle is at idle or moving at low speeds.
All models have two fans. The main fan is 320 mm (12. 6 inches) in diameter with seven blades to aid
the airflow through the radiator and the condenser. An electric motor attached to the radiator support
drives the fan.
The auxiliary fan is 320 mm (12.6 inches) in diameter.
A/C Off or Non-AC Model ▶
The cooling fans are actuated by the engine control module (ECM) using a low-speed cooling
fan relay, a high-speed cooling fan relay and a cooling fan motor relay.
The ECM will turn the cooling fans on at low speed when the coolant temperature reaches
95°C(203°F) and at high speed when the coolant temperature reaches 105°C(221°F).
The ECM will change the cooling fans from high peed to low speed at 100°C(212°F) and
will turn the cooling fans off at 90°C (194°F). -

A/C On ▶
The ECM will turn the cooling fans on at low speed when the A/C system is on. The ECM will
change to high speed when the high side A/C pressure reaches 1860 kPa (269.8 psi).
The cooling fans will return to low speed when the high side A/C pressure reaches 1378 kPa
(199.8 psi). -

7) Engine Coolant Temperature Sensor
The Engine Coolant Temperature (ECT) sensor uses a temperature to control the signal voltage to the
Engine Control Module (ECM).
8) Coolant Temperature Gauge
The coolant temperature gauge controls the instrument panel temperature indicator. The coolant
temperature gauge is located with ECT sensor.

COMPARTMENT
The label attached on each fuse box
indicates only major fuses and
relays. Therefore, there are more
fuses and relays than indicated. For
details about the connection of fuses
and relays, refer to the power
distribution circuit diagram on the

The relays in the ICM box cannot be replaced respectively; so if the any of the components on
the PCB are defective, they should be replaced as an assembly.
