  Resistor, Resistor Assembly

• Description:

  This is the genuine Ford engine cooling fan resistor for the 2010-2014 Mustang equipped with the high-output cooling system, covering the 3.7L V6 and 5.0L V8 as well as the 5.4L supercharged applications. The resistor drops voltage to the electric radiator cooling fan motor so the fan can run at a lower speed, giving the powertrain control module a low and high fan stage for proper engine temperature management. When this resistor fails the cooling fan often defaults to only high speed or stops running at low speed entirely, which drivers notice as a fan that roars constantly, an engine that runs hot in traffic, intermittent overheating, or a check engine light with fan-circuit codes. Because it sits in the airflow path and carries continuous current, the internal element and connector are a common heat-related wear item. This is the factory Ford part matching the original resistor assembly, ensuring correct resistance value and connector fit. Catalog name Resistor, part number BR3Z-8L603-A. Inspect the mating connector for melting or corrosion before installing the new unit.

• Notes: Included with fan assembly.
