Universal brackets...without variable speed control 
The brackets provided with this kit are intended to mount the electric fan to the radiator. Due to the number of 
variances in specific makes and/or models, additional brackets may be required.
INSTALLATION INSTRUCTIONS
REMOVE EXISTING FAN & SHROUD ASSEMBLY:
1.  Remove plastic radiator cover, and top half of fan shroud (some shrouds are a single piece). 
2.  Remove fan and clutch assembly. If clutch is mounted to pulley with four bolts, remove nuts, remove clutch/
fan assembly and replace nuts. The clutch may be mounted by a large single nut. It may be possible to 
remove this clutch by fitting a large wrench to the nut. Put a rag over the fan to keep from being cut. Hold the 
fan in place and pull the wrench in the direction of rotation. It may help to give the end of the wrench a sharp 
strike from a soft-blow hammer to break the nut free without the pulley slipping. 
3.  Remove the lower shroud.
ASSEMBLE ELECTRIC FAN ASSEMBLY:
1. Look at the vehicle construction around the radiator for potential mounting points. Mounting points for the fan 
serves two purposes; to carry the weight of the fan, and to hold the fan against the radiator core. Cross brac-
es, radiator trays, front facia, and radiator-mounting points are possible mounting points for these brackets. 
2.  Whenever possible we do not recommend mounting the brackets to the radiator core so that the core carries 
the weight of the fan. In some applications this can cause damage to the radiator core.
3.  Locate at least four points to mount the fan to the vehicle that will support the weight and secure the fan to the 
radiator.

Part number 298 fan package does not come with a controller. Operation 
of the fans will require that you use a controller and fuse to protect the 
fan motors. There are many switches and controls available, some can 
be found on our website www.flex-a-lite.com. Be sure that the switch and 
relay used will handle the current drawn by the fan. The fan motors are 
wired with a RED and BLACK wire. 
The RED wire on this fan assembly is 
the POSITIVE wire. The BLACK wire 
is the GROUND wire.
