PROCEDURE:
1. REMOVE CONTENTS FROM BOX. VERIFY ALL PARTS ARE PRESENT. READ
INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION. MINOR TRIMMING
MAY BE REQUIRED.
2. Start installation under the front of the vehicle, (Figure 1). Remove the two factory bolts
holding the driver side tow hook in place and remove the tow hook from the vehicle. NOTE:
Tow hooks cannot be reinstalled with this Grille Guard. Apply a protective layer of removable
tape, (masking tape for example), to the inside of the inlets in the plastic bumper for the tow
hook, (Figure 2).
3. Select the driver side frame Mounting Bracket. From behind the bumper, insert the Bracket
through the inlet for the tow hook, (Figure 3 & 4). Line up the (2) holes in the Bracket with the
holes for the tow hook hardware. Bolt the Bracket to the frame with (2) 12mm x 35mm Hex
Bolts, (4) 12mm Flat Washers, (2) 12mm Lock Washers and (2) 12mm Hex Nuts. Remove the
protective tape. Do not tighten hardware at this time.
4. Repeat Steps 2 - 3 for passenger side Mounting Bracket installation.
5. Open the hood and using a flat screwdriver, remove the clips holding the plastic cover in place
on top of the radiator, between the radiator and the grille insert. Gently pry up the center button
to release, then remove entire clip.
6. Remove the grille insert. NOTE: Use a pair of “needle nose” pliers to squeeze the grille
mounting clips to release, (Figure 5). Once all clips have been released and any other
hardware removed, gently pull the grill insert forward from the vehicle.
NOTE: It may be necessary to trim some material from the end of the air intakes in the
lower bumper cover to provide additional clearance for the Mounting Brackets.

7. Pull back the rubber air deflector at the driver side-bottom of the grille opening to locate the top
bumper bolt, (Figure 6). Remove the factory bolt, (Figure 7). Select the driver side Top
Mounting Bracket. Apply a section of Adhesive Backed Foam Tape to the underside of the Top
Bracket to prevent the Bracket from scratching the plastic bumper cover, (Figure 8A & 8B).
Trim as necessary. Next, line up the bottom hole in the Bracket with the hole in the bumper
bracket and bolt the Top Bracket to the bumper bracket using the factory hex bolt, (Figure 9).
Repeat this step for passenger side Top Bracket installation.
8. With assistance, hold the Grille Guard up to the outside of the Frame Mounting Brackets. Align
the holes in the Frame Mounting Brackets with the Grille Guard and bolt together using the
included (6) 12mm x 35mm Hex Bolts, (12) 12mm Flat Washers and (6) 12mm Nylon Lock
Nuts, (Figure 10). Do not tighten hardware at this time.
9. Attach the Grille Guard to the Top Brackets using the included (2) 10mm x 30mm Button Head
Bolts, (4) 10mm Flat Washers and (2) 10mm Nylon Lock Nuts, (Figure 11). NOTE: Insert the
10mm Button Head Bolt with 10mm Flat Washer in from the outside of the Grille Guard. Do not
tighten at this time.
10. Level and adjust the Grille Guard and tighten all hardware.
11. Reinstall the grille insert and plastic shroud using the factory hardware.
12. Do periodic inspections to the installation to make sure that all hardware is secure and tight.
