Engine Tune-Up for GMC Sierra 2500 HD

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to GMC Sierra 2500 HD engine tune-up services. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your Sierra 2500 HD's filters, specifically replacing the air filter and fuel filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your Sierra 2500 HD’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your Sierra 2500 HD can determine what kind of service it needs. If you’re not sure what services are the best fit for your car, let us help! Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Common Engine Tune-Up Q&A For 2021 GMC Sierra 2500 HDs

  • Will it hurt my GMC Sierra 2500 HD to drive with old spark plugs? Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.
  • What does a puddle underneath my GMC Sierra 2500 HD mean? Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.
  • Are some driving habits better for my GMC Sierra 2500 HD engine than others? Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.
  • Where can I have a GMC Sierra 2500 HD tune-up done? At the nearest Firestone Complete Auto Care! We’re ready to help service, maintain, and repair your GMC Sierra 2500 HD.
  • How frequently do the fuel injectors in my GMC Sierra 2500 HD need to be cleaned? The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.
