MOUNTING
1. Install the Rubber Fan Shroud Seal. (See Diagram #4)
2. Position the electric fan in the desired location. Taking the
Angle Brackets supplied determine the best locations for a
good rigid mount. (See Diagram #2 & 3)
3. Take the four Angle Brackets, 1/4” Hex Bolts, Washers
and Nyloc Nuts provided and attach brackets to the fan
shroud in the desired location.
Flat washers must go between the Angle Bracket
and the shroud. (See Diagram #4)
4. In some applications where the radiator flange is not right
up against the fan shroud, longer bolts can be used to
space Angle Brackets properly. Hardware not included.
(See Diagram #5)
5. Using the remaining 1/4” Hex Bolts, Washers and Nyloc
Nuts provided, mount the Fan Shroud Assembly to the
radiator. (See Diagram #4)
In some cases the radiator flange may have to be
drilled for proper alignment.
