Viscous Fan Drive - New Holland T8010 Manual

Section 50 - Climate Control - Chapter 2

VISCOUS FAN DRIVE

Since the viscous fan c reates air flow at the
condenser, a properly functioning fan drive is
essential to proper air conditioning performance. A
defective fan drive can cause engine overheating
and/or high pressure switch activation. But a plugged
grille, radiator, condenser and oil cooler can also
cause the same.
To separate a fan drive problem from other possible
causes, perform the Viscous Fan Drive Test in this
manual.
NOTE: When performing the viscous fan drive test,
the air conditioning system should be OFF.
