Intrepid V6-2.7L VIN R (2003)
EXCEPT 2.7L BASE
The cooling system uses two fans. Both fans operate at two different speeds, low and high. Depending on engine coolant temperature and A/C system
high side pressure, the fans operate at either low or high speed. The PCM controls radiator fan speed by grounding the coil side of either the HI/LO
fan relay or the HI fan relay. Low speed radiator fan function is achieved by running both fan motors in a series circuit. High speed radiator fan
function is achieved by running both fan motors in a parallel circuit. Refer to WIRING DIAGRAMS.
