Fan Cooling Pump
The fan cooling pump (Figure 2-6) is part of the open
hydraulic system and is a variable-displacement pump that
provides flow to the cooling fan motor. The displacement is
controlled by a solenoid valve HS-504, driven by node 5. The
control software uses the following inputs to determine
where to set the pump displacement:
• Fan cooling pump pressure
• Hydraulic tank temperature
• Engine coolant temperature
• Air intake temperature
• AC compressor switch setting
