Dual Electric Fan
Shroud Assembly
Part No. 16812
Note: This unit is designed for
puller applications (engine side
of radiator). Using this unit as a
pusher reduces fan CFM and
restricts static airflow through
radiator.
Mounting Instructions
1. Position fan assembly against
the radiator in the desired
location. Take the plastic
mounting rods and carefully
push the rods thru the eight
holes in the fan shroud and
into the radiator core.
Caution: Do not use excessive
force when pushing the rods
thru, you could puncture the
radiator.
2. Use plastic clips to secure the
fan in place. The clips can only
be used in one direction. Push
the clips over the plastic rod
until snug against the radiator.
Cut off any excess rod.
