ENGINE COOLING SYSTEM
5) WATER PUMP
The belt-driven centrifugal water pump consists of an impeller, a drive shaft, and a belt pulley.
The impeller is supported by a completely sealed bearing.
The water pump is serviced as an assembly and, therefore, cannot be disassembled.
6) ELECTRIC COOLING FAN
Keep hands, tools, and clothing away from the engine cooling fans to help prevent
personal injury. This fan is electric and can turn on even when the engine is not running. -
f a fan blade is bent or damaged in any way, no attempt should be made to repair or reuse
the damaged part.
A bent or damaged fan assembly should always be replaced with a new one to prevent
possible injury. -
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 ai
r
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.
7) 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). ·
