Cooling Fan (Crankshaft driven)
DISASSEMBLY AND INSTALLATION
IDo not release the drive belt tension by removing the fan/water
pump pulley.
I Fan coupling cannot be disassembled and should be replaced
as a unit. If front mark q
Fis present, install fan so that side
marked q
Ffaces the front.
I 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.
