MOUNTING OPTIONS

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.
