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.
