Cooling Fan, 2.3L

The system consists of a single speed fan attached to the fan shroud behind the radiator. The system is wired to operate only with the ignition switch in the RUN position, preventing operation of the cooling fan when the ignition switch is in the OFF position.

The cooling fan is controlled during vehicle operation by the constant control relay module (CCRM) and powertrain control module (PCM) 12A650 which energizes the cooling fan under the following conditions:

1. Engine temperature higher than normal. Fan starts operating at 105°C (221°F) and stops when temperature drops to 94°C (200°F).
2. A/C ON and vehicle speed does not provide enough natural airflow (fan starts running at or below 69 km/h (43mph) and stops at 77 km/h (48 mph).

 WARNING: DISCONNECT THE COOLING FAN PRIOR TO PERFORMING ANY UNDERHOOD SERVICE SINCE THE FAN COULD CYCLE IF THE IGNITION SWITCH IS LEFT IN THE ON POSITION EVEN THOUGH THE ENGINE IS NOT RUNNING.
