GMC Sierra 2500 HD Bumper

GMC Sierra 2500 Bumper: Maintenance Pointers to Prolong its Use

Back in the day, bumpers used to be as simple as a steel bar bolted in front of the car. But advances in engineering and car safety have made modern bumpers like the one GMC Sierra 2500 HD into a system of panels, fasteners and other components. And this level of complexity also makes the bumper vulnerable to wear or damage. Thankfully, this can be averted by regular care and maintenance of the bumpers.

Maintaining the GMC Sierra 2500 bumper is fairly easy as it is similar to maintaining the other exterior body panels of your truck. In this guide, we'll share some key maintenance tips for your Sierra's bumpers.

  • Wash the bumper by hand.

Although a drive-in car wash can save time, they actually do a poor job in cleaning the bumpers. Instead, take the time to clean the bumpers by hand. Apply car shampoo mixed with water on the bumper using a sponge, and scrub in a circular motion. Pay extra attention to the vents and crevices, as these areas are often where debris accumulates. Rinse well and wipe with a clean cloth to dry.

  • Remove hard water stains with white vinegar.

Characterized by their whitish, powdery appearance, hard water stains are caused by water that has a high mineral content and cannot be removed by conventional washing. Instead, rub a piece of cloth soaked in undiluted white vinegar, whose acidic properties should cause the minerals to break down. You can also use a commercial all-purpose bathroom cleaner, which also has the same effect, although you will need to wear gloves as these cleaners also contain chemicals that are harsh on the skins.

  • Fix minor dents with hot water.

Dents are among the common problems of bumpers, but minor cases can usually be remedied by a kettle of hot water. Simply pour the water on the dented area and, while it is still hot, use a plunger to pop the panel back into place. Once it returns to its original shape, pour cold water onto the area to prevent it from reverting to its dented state. You can also use the same technique with a hair dryer, although it will take longer for the bumper surface to heat up sufficiently.

  • Installation Tips for your GMC Sierra 2500 Bumper

    Whether it is to replace broken down bumper or upgrading to a custom one, installing a new bumper for your GMC Sierra 2500 HD can be quite an exciting experience. Although bumpers have become more complex in construction and design over the years, they are still easy enough to install on your own, provided that you have the necessary tools and time on hand of course.

    If you are planning on installing a GMC Sierra 2500 HD bumper, here are some tips that you might find useful:

    Tip #1: Before removing the bumper, get all the electronics out of the way first

    The bumper in the GMC Sierra is connected to the fog lights and auxiliary lights and its wiring, so make sure to remove these first before taking out the bumper. These automotive lights are typically secured by screws and plastic fasteners, so removing these should be as easy as loosening the screws and pushing the tabs apart. However, take care not to touch or shake the bulb as they are quite fragile.

    Tip #2: For unpainted bumpers, do some sanding first

    Unpainted bumpers usually come out of the packaging pre-primed and with bumps on the surface. Wash the bumper with your preferred car shampoo to remove any dust and chemicals left over from the molding process, and wet sand the areas with bumps and rough areas. As for painting, we recommend having it done in an auto body shop as a professional paint work is much better looking than a spray paint job.

    Tip #3: Secure the foam absorber with duct tape

    The foam absorber, which is sandwiched between the bumper cover and the bumper core, tends to fall off after removing the cover. To prevent this, tape the absorber to the core using duct tape; you can take it off once you are ready to reinstall the bumper cover.

    Tip #4: Loosen stubborn bolts with penetrating oil

    Having trouble getting those bumper bolts loose? Try spraying it with penetrating oil and let it sit for several minutes first. The oil should break through the dirt and rust that's keeping the bolt stuck in place.
