Will it hurt my GMC K3500 to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on GMC’s recommendations.

What should I do if I see leaks under my K3500?

Don't ignore puddles of fluid under your GMC K3500. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are some driving habits better for my GMC K3500 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.

How frequently do the fuel injectors in my GMC K3500 need to be cleaned?

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, particularly if you want to keep your 1985 GMC K3500 in tip-top shape. Routine engine tune-ups can bring power back to your K3500. Tune-ups help your engine start smoothly and run efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you take your car for regular engine tune-ups as recommended by GMC, you can rest assured you’re investing in your K3500’s long-term engine performance.

GMC K3500 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to GMC K3500 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 K3500'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 K3500’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your K3500's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
