COOLANT FAN FUNCTIONAL CHECK
3.0L, "C" SERIES
The cooling fan on the "C" Series with 3.0L engine is a 2-speed, 150-watt system. It has a low speed, solid state relay that has an ECM control. The
cooling fan will operate at low speed whenever the ignition is "ON" and the A/C select switch is set on A/C. The fan will go "OFF" when A/C is selected
if TCC is also engaged.
The fan will go on high speed whenever engine coolant temperature exceeds approximately 108°C (226°F). This will occur regardless of A/C or TCC
engagement.
With the heavy duty cooling option (V08), two fans are used. The second fan only operates when high speed is called for. With (V08), both fans run
during high speed.
