Tune-Ups to Help Your GMC C1500 Run Better

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you drive a 1985 GMC C1500. Routine engine tune-ups can bring power back to your C1500. 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 get routine engine tune-ups based on GMC's recommendations, you’re taking vital steps toward keeping your C1500’s engine running smoother, longer.

GMC C1500 Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1985 GMC C1500. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your C1500'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 C1500’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 C1500 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Questions About 1985 GMC C1500 Engine Tune-Ups

  • When should GMC C1500 spark plugs be replaced? 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 do I do if I see a pool of liquid under my GMC C1500? 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.
  • What do hard starts and stops do to my C1500 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.
