5. Next, open the hood and remove the plastic cover between the top of the grille and the radiator. NOTE:
Use a small flat head screw driver to pop up the center of the plastic clips. Remove the two outer bolts
from the grille shell. Use
a pair of “needle nose” pliers to carefully squeeze the back of the clips to release
as you gently pull the grill forward, (Figure 9). IMPORTANT: Do not damage the clips holding the grille in
place. Once all of the clips have been released, carefully remove the grille by gently pulling it forward from
the vehicle
6. Remove the long factory top bumper bracket bolt behind the bumper on the top of the frame. Select the
driver side Top Bracket. Apply a layer of Adhesive Backed Foam Tape to the inside of the Bracket to
protect the finish on the bumper, (Figure 10). IMPORTANT: To prevent the Top Brackets from damaging
the finish on the vehicle during installation, cover the top of the bumper with removable tape, (masking
tape). Secure the Top Bracket to the bumper bracket with the factory hex bolt, (Figure 11). Leave the
hardware loose at this time. Repeat this Step to install the passenger side Top Bracket.
7. With assistance, hold the Grille Guard up in position on the outside of the Mounting Brackets. Bolt the
Grille Guard to the Brackets with (6) 12mm x 30mm Hex Bolts, (12) 12mm x 32mm Large Flat Washers
and (6) 12mm Nylon Lock Nuts, (Figures 7A & 8B). Snug but do not tighten hardware at this time.
8. Line up the driver side Top Bracket with the hole in the upright on the Grille Guard. Bolt the Top Bracket to
the upright with (1) 10mm Button Head Bolt, (2) 10mm Flat Washers and (1) 10mm Nylon Lock Nut,
(Figure 12). Do not tighten hardware at this time. Repeat for passenger side Top Bracket installation.
9. Level and adjust the Grille Guard. Make sure that the Top Brackets do not come in contact with the top of
the bumper cover.
a. Vehicles equipped with tow hooks and/or opening in bumper cover: Proceed to tighten all
hardware.
b. Vehicles without tow hooks and no openings in bumper cover: Tighten the lower Mounting
Bracket hardware only. Temporarily remove the Grille Guard. Hold the lower bumper cover up in
position and mark the location of the Mounting Brackets onto the back of the cover. Cut (2) vertical
slots through the bumper cover to clear the Brackets. Cut as little as possible from the bumper
cover. Reinstall the bumper cover over the Brackets. Reinstall the Grille Guard as described in
Steps 7
– 8. Level and adjust the Grille Guard and tighten all hardware at this time.
10. Once all mounting hardware is tight, line up the clips on the grille with the mounting tabs, (Step 5), and
gently push the grille back into place. Reinstall the top plastic cover.
11. Do periodic inspections to the installation to make sure that all hardware is secure and tight.
To protect your investment, wax this product after installing. Regular waxing is recommended to add a protective layer over
the finish. Do not use any type of polish or wax that may contain abrasives that could damage the finish.
For stainless steel: Aluminum polish may be used to polish small scratches and scuffs on the finish. Mild soap may be used
also to clean the Grille Guard.
For gloss black finishes: Mild soap may be used to clean the Grille Guard.
