1.) Remove the seat and right radiator shroud. Unbolt the gas tank
and prop it up an inch or two for an easier installation process.
2.) Install the three supplied mounting bolts to the fan
bracket. Slide the plastic spacers over the bolts on the
back side of the bracket and install retaining washers to
hold the spacers in place.
(see photo to left) Do not push
the retaining washer all the way down against the bracket.
The extra spacer is for the 250x. (see note below)
3.) Install clip nuts on radiator mounts. Position the clip nuts as shown
below.
For CRF 250X models only:
If bike is equipped with an air suction valve, disconnect
factory wiring connectors from the air suction valve bracket
near the radiator. Remove the bolt holding the air suction
valve bracket to the frame. Rotate the air suction valve
down (clockwise as viewed from the riding position) so that
the bracket is out of the way. If bike does not have an air
suction valve, unbolt the factory wiring harness bracket
from the frame and move down and out of the way.
The upper fan mounting ear
interferes with the top radiator
tank and must be trimmed. Remove the fan to bracket screw
(T20
Torx)
. Trim 1/8” (3mm) from the fan mounting ear using a hacksaw,
Dremel, or side cutters. Place the extra supplied plastic spacer on
the fan screw and reinstall.
(See photo to right) Recommended
torque is 20 in-lb (2.5 Nm).
4.) Attach the fan mounting bracket to the radiator.
A 4mm ball-end hex key is recommended for
ease of installation. Recommended torque is 50 in-lb (5.5 Nm).
5.) Ensure the engine and radiator are cool to the touch before installing the temperature sensor.
It is not necessary to fully drain the cooling system. Remove the radiator cap to relieve any
pressure, then reinstall cap. Place a drain pan underneath the radiator to catch drips. Unscrew the
drain plug from bottom of radiator and quickly screw in the temperature sensor with the copper
sealing washer installed. Tighten the temperature sensor to 15 ft-lb (20 Nm) and plug into
connector on fan assembly.
