GMC Sierra 1500 Exhaust System

Easy Maintenance Tips for GMC Sierra 1500 Exhaust Systems You Can Do at Home

Proper maintenance of the exhaust system of your GMC Sierra 1500 will not only allow these parts to run at full capacity but also extend their service life as well as that of the vehicle. And while some exhaust tune-ups that are best done by professional mechanics, there are maintenance tasks that you can do at your own garage that can help keep your truck running in good condition.

Here are some easy maintenance tasks for the GMC Sierra 1500 exhaust system that you can do at home.

  • Look out for warning signs.

A regular hands-on inspection is the first and most effective step in ensuring the condition of the exhaust system components of your truck and addressing any problems as soon as possible. While the truck is fully lifted and supported by jack stand, check the underside for the condition of your vehicle's exhaust components. Look for obvious signs of rust, cracks, and other types of damage, and check if any of the parts have come loose. Make sure that the exhaust parts have cooled down significantly before touching any of them with your bare hands.

  • Take note of any unusual noise.

In addition to an ocular inspection, you should also pay attention to the noise your truck's exhaust generates. A noticeable increase in noise, for instance, might indicate that the exhaust is under heavy strain due to a leak in the pipes, while knocking or popping noises might signal backpressure caused by a clogged pipe. Rattling sounds may also mean a section of the exhaust pipe or muffler has come loose, so make sure to check that as well.

  • Invest in some good tools.

Knowing what warning signs to look for in your exhaust system is not enough, however, as you also need to have the proper tools necessary to check and immediately address any problems your truck's exhaust might have. These include a pipe cutter, which allows you to cut off and remove any corroded or damaged portions of the exhaust pipe, and exhaust hanger removal pliers to remove any loose or damaged hangers and hanger brackets. If you plan on replacing broken exhaust pipes yourself, it is also recommended for you to invest in exhaust pipe expanders to make installing new pipes an easier task.

  • Simple Ways to Diagnose Problems in the GMC Sierra 1500 Exhaust System

    Strange exhaust noises are a common warning sign that the GMC Sierra 1500 exhaust system is on the fritz, but it isn’t the only symptom of bad exhaust. In fact, even if the car sounds just fine, the muffler, catalytic converter, and other exhaust parts can be exhibiting their malfunction through other means. And finding and diagnosing what these problems are is essential in preventing long-term damage in your pickup truck and ensuring optimum driving performance for many years to come.

    In this guide, we’ll show you how to diagnose and troubleshoot common GMC Sierra 1500 exhaust system problems.

    Check out for abnormal noises.

    Of course, abnormal noises from the exhaust are the first things to indicate that something’s wrong with the exhaust. A louder exhaust, for example, may mean that the exhaust pipes are under heavy load or there is a hole in the pipe where air is escaping. Chugging, knocking, or popping noises, on the other hand, suggest backpressure due to a blocked exhaust.

    Do a visual inspection.

    In addition to sound, an ocular inspection of the vehicle can also give you a good idea of your truck’s exhaust problems. With the car lifted up and supported by jack, slide under the car and look for any signs of rust, cracks, or other signs of damage. Do this in every section of the exhaust pipe, and use your hand to check for any loose components.

    Make use of tin foil.

    Another great way to determine the problem in a malfunctioning exhaust system is tin foil. Wrap the foil around the pipes and other parts of the exhaust and start the engine. The foil should muffle the sounds from the exhaust, and a part where the exhaust noise is much quieter may indicate a leak or other problem in that particular area.

    Check for any vibration.

    Seriously damaged or worn exhaust parts can also cause the car to vibrate violently especially after stepping on the gas. While sitting inside the car, pay attention to whether you can feel large vibrations on your feet than normal. If there is, the exhaust system is likely straining to function properly.

    Take note that if you notice any or all of these instances in your GMC Sierra have it checked by a mechanic immediately to make the necessary repairs or replacement of the exhaust parts.
