Usual Problems of Chevrolet Trailblazer Header Panel and the Reasons behind Them
Your Chevrolet Trailblazer is armed with a fierce-looking fascia. This masterpiece is the sum of several components, which are combined not only to make the SUV look amazing but also to provide room for the engine and other safety features. One of these parts is the header panel. Often made from sturdy steel materials or fiberglass, your Chevrolet Trailblazer header panel can be found on your SUV's facade, just behind the grille. Aside from its aesthetic value, it also serves as the mounting point where the grille and the headlights are attached. Although it was expected to be strong enough to last for years, the header panel is bound to wear at some point. The following symptoms indicate that your Chevrolet Trailblazer header panel's prime years are probably over:
Rust and corrosion
Constant exposure to varying temperatures and weather conditions make the header panel highly susceptible to rust accumulation and corrosion. Moisture from all forms of precipitation and fog promote oxidation, while the extreme working conditions of the engine speeds up the accumulation of corrosive materials. All these things combined, your header panel will eventually succumb to wear. Proper maintenance may help, but once rust covers up the panel's entire surface, you will have no other choice but to replace it with a new one.
Rattling and clunking noises
The header panel is usually attached to the engine bay through a couple of mounting brackets and screws. Probably because of road bumps and high-speed driving, these bolts tend to become loose over time. As a result, the header panel will move freely. Its interaction with the engine block behind it and the grille assembly in front will produce clunking and rattling noises, which are both very annoying and embarrassing. The worst part is that the panel's movements may cause minor to severe damage on your Chevy Trailblazer's engine components, particularly the radiator and the condenser, which are often located at the front portion of the hood. If you have this problem, you can just tighten the mounting screws and protect them from rust with WD-40.
The location of the header panel is not really ideal; in fact, it is very compromising. Aside from the bumper and the bumper cover, your header panel is also part of your vehicle's first line of defense against high-intensity impacts. When your vehicle gets into a head-on collision or fender-bender, the severe cracks and dents that the header panel will acquire may already be enough to abruptly end its service life. In this case, its immediate replacement is a must.
