Engine Cooling Fan: Operation: Mustang

Cooling fan system consists of a single-speed fan motor. Cooling fan operates only when ignition is on. Integrated Relay Controller Module (IRCM) and Electronic Engine Control (EEC-IV) module controls cooling fan.

Cooling fan turns on when engine coolant temperature is greater than 216°F (102°C), or when A/C is on and vehicle speed does not provide enough airflow. IRCM is located in engine compartment, near right shock tower. EEC-IV module is located in right kick panel.
