Radiator Fan Motor Operation:
The cooling fan motor, located behind or in front of the radiator, is a small, direct current motor that rotates metal or plastic fan blades to pull or push air through the radiator. As this air passes over the radiator's fins and tubes, it draws heat away from them and reduces the temperature of the engine coolant.
How To Instructions:
- Check for obvious problems.
- Out with the old, in with the new.
