Use the appropriately sized socket wrench and remove any bolts from the locations where the grille guard will be mounted. The locations vary depending on the vehicle and grille guard make. Follow the instructions provided with your grille guard to locate and remove the correct bolts.
Slide the grille guard into the correct location, matching the guard’s mounting holes to the spots where the bolts were removed. Have an assistant hold the guard once it’s in position.
Place a washer onto each of the mounting bolts provided with the guard. Slide the bolts through the guard's mounting holes and tighten them with the appropriate-size wrench.
Pull firmly on the guard ensuring it's tightly fastened in place before driving.
