How to Repair a Bent GMC Billet Grille
Grille works three-way. It primarily aids in preventing engine overheating by blowing cool air into the engine area and into the radiator. While doing so, it also blocks roadway debris that might cause damage in any of the vital parts that are located under the hood. And as one of the highlights of the vehicle's fascia, the grille definitely boosts the appearance of your car. For that matter, the aesthetic design of GMC billet grille is made to complement the car's overall look. But when it becomes bent due to an accident or age, a repair can still be done.
Difficulty level: Moderate
Things you'll need:
- Anodized flat aluminum bar or scrap aluminum bar
- Mill vice and large aluminum parallel clamp or hammer
- Acetylene and welding rod
- Hand drill
Step 1:Remove the entire billet grille assembly in order to get the particular bar that has been bent. Depending on the mounting hardware, you may need screwdrivers and wrenches to undo the attachments.
Step 2:Lay the assembly on a working table, and take everything apart, including the billet grille bars, spacers, connecting rods, as well as the top and bottom plates.
Step 3:Get the bent billet grill bar, and inspect whether it could possibly regain its straight form. Remember that a bend may actually be a mix of curve and a kink that goes the opposite directions. This kind of damage is hard to fix, so just cut the bent portion off.
Step 4:Straighten the bar using a mill vice and a large aluminum parallel clamp. If you do not have these tools, you may use a hammer instead. After that, the part that is hard to straighten will become obvious. That part is to be removed.
Step 5:Using a marker, mark the portion where you should cut using a handheld grinder
Step 6:Cut a piece from the anodized aluminum bar that's of the same length that was removed from the billet grille. This piece is the one that will be used to supply as a new section in place of the portion that was removed. You can also get that piece from a scrap aluminum bar that has the same thickness as the bars of your GMC billet grille.
Step 7:Smoothen out the edges of the aluminum piece for the new section. If you don't have a belt sander, you may use a grinder with its sanding disc on.
Step 8:Weld the new section to the billet grill bar, and then, smoothen out the connecting point with the grinder. Work until the new section blends out with the original piece. Polish all sides until no welded portion is visible.
Step 9:If the new section should cover the portion through which a connecting rod should go, you need to make a hole on it with a hand drill. Make sure to use the drill bit that would create a hole that's just right for the connecting rods.
Step 10:Paint as necessary. And then, reassemble all parts of the GMC billet grille back.
