GMC Jimmy Grille

How to Find the Reasons why a GMC Jimmy Grille Fails

Your GMC Jimmy grille is a car component that is located directly in front of your radiator. It draws in huge amounts of cold air to the engine to lower the temperature inside the combustion chamber. Aside from improving air flow, it also enhances the look of your truck. Whether you install a mesh, billet, or CNC grille, it doesn't matter as long as it is functioning properly. However, there will come a time when the grille would begin to show some signs of problems. When this happens, you have to be very keen in finding out the culprits behind Jimmy grille issues.

Knocked-out bars or mesh

Several things can ruin your grille. Hitting a wall or another vehicle is one of those. Such road mishaps can damage your grilles physically. The strong impact and shock can knock some of the metal bars or aluminum mesh out. Having a messed-up grille is really annoying. Even if you try to solder or weld the broken part back, it would be really impossible to restore the original look of your grille. The best thing that you can do is to install a new grille. For a more customized look, you can even design and make your own grille.

Scratched and dented plastic grilles

Some GMC Jimmy grilles are made of Styrene or ABS plastics. These grilles are strong, but they are not as durable as metal grilles. Plastic grilles may incur scrapes and fractures, especially when they get scuffed by sharp objects. Some scratches are very small, so you need to have keen eyes to find them. During visual inspection, use a flashlight and a magnifying glass to aid your vision. Mark the spots that require repair. Apply gap-filling cement on the damaged surface to smoothen it out.

Corroded chrome grilles

Not all metal grilles can resist corrosion; aluminum and stainless-steel grilles can, but chromed-steel grilles can't. Once the silver coating of these grilles chip, they lose the ability to fight rust. Rust is very easy to detect. You just have to look close enough and inspect the corners and edges of your grille. Check the spots where the silver paint starts to flake. Sand the rusty parts using a low-grit sandpaper to remove rust. After scraping rust off, you can repaint your chrome grilles to give them a brand-new appeal.

  • Four Rules to Make Your GMC Jimmy Grille Last 27 February 2013

    Every car owner wants to make his GMC Jimmy grille last, not just to save money but also to keep his vehicle protected for a very long time. To make this happen, there are certain rules to follow. These are simple yet very effective ways that can prolong the service life of this car component.


    Rule no. 1: Keep your grille clean.

    Your grille doesn't have the ability to protect itself from dirt and pollution. It's your job as a responsible car owner to keep your grille squeaky clean. There are just two things that you need to do: wash and brush. Wash your grille with soapy water. Brush the grille to remove filth and grime. It's that simple.


    Rule no. 2: Keep your grille rust free.

    A grille that is made of chromed steel and other poor metals can get corroded over time. But you don't have to throw it right away. There are things that you can do to restore this grille. First, you have to sand its surface to remove rust buildup. Paint the grille after to improve its look and inhibit corrosion. Through this, you can save a handful of cash.


    Rule no. 3: Keep your grille scratch free.

    Scratches and splinters on your grille are inevitable. Good thing, the repair procedure for cracks is very easy to pull off as long as you have the necessary tools and devices. You'll need acrylic solvent cement and gap-filing cement to remove holes and fractures on the grille surface. For bigger dents, use epoxy-based filler because it adheres better on plastic surfaces. Solvents are flammable, so apply these products with utmost care.


    Rule no. 4: Keep your grille securely attached.

    Make sure that your grille is mounted properly on your truck's bumper to prevent it from falling off. Loose bolts and screws can cause the grille to shake whenever the vehicle is moving. It will also produce a loud, clanking noise, which is really annoying. Retighten the bolts or reattach the plastic rivets as often as possible to keep the grille snugly in its mounting position.
