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.
