2.0L (SVT)
The electric cooling fan system consists of a single speed cooling fan controlled by Powertrain Control Module (PCM). One relay controls the cooling fan. The electric cooling fan is activated when ignition switch is in ON position and engine coolant exceeds a specified temperature.
The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, etc.) to determine engine cooling fan needs. The PCM controls the fan operation through the engine cooling fan control output.
2.0L (EXCEPT SVT)
The electric cooling fan system consists of 3-speed cooling fans controlled by Powertrain Control Module (PCM). Four relays control fan speed. Electric cooling fans are activated when ignition switch is in ON position and engine coolant exceeds a specified temperature. Cooling fans are also active when A/C is on.
The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, A/C on/off status, A/C pressure, etc.) to determine engine cooling fan needs. The PCM controls the fan operation through the 3 engine cooling fan control outputs.
2.3L
The electric cooling fan system consists of 2-speed cooling fans controlled by Powertrain Control Module (PCM). Two relays control fan speed. Electric cooling fans are activated when ignition switch is in ON position and engine coolant exceeds a specified temperature. Cooling fans are also active when A/C is on.
The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, A/C on/off status, A/C pressure, etc.) to determine engine cooling fan needs. The PCM controls the fan operation through the high fan control output and the low fan control output.
