Tune-Ups to Help Your GMC C2500 Run Better

Is it tune-up time? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 1988 GMC C2500’s engine to last for a long time. Routine engine tune-ups can bring power back to your C2500. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by GMC, you invest in your C2500's long-term health and engine performance.

GMC C2500 Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several GMC C2500 engine tune-up services. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your C2500's filters, specifically replacing the air filter and fuel filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your C2500's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your C2500 can determine what kind of service it needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. 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 1988 GMC C2500s

  • Will it hurt my GMC C2500 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 C2500 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 hard starts and stops bad for my GMC C2500 engine? You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.
