2000 NISSAN PATROL Electronic Repair Manual

11. Remove radiator.
12. After repairing or replacing radiator, install all removed parts
in reverse order of removal.
Cooling Fan (Crankshaft driven)
DISASSEMBLY AND INSTALLATION
+Do not release the drive belt tension by removing the fan/
water pump pulley.
+Fan coupling cannot be disassembled and should be
replaced as a unit. If front mark
jFis present, install fan so
that side marked
jFfaces the front.
+Proper alignment of these components is essential. Improper
alignment will cause them to wobble and may eventually
cause the fan to separate from the water pump causing
extensive damage.

The following tables show the normal maintenance schedule. Depending upon weather and atmospheric
conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent
maintenance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.
