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. 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 does a puddle underneath my GMC C2500 mean?

Don't ignore puddles of fluid under your GMC C2500. 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.

What do hard starts and stops do to my C2500 engine?

Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

Engine Tune-Up for GMC C2500

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to GMC C2500 engine tune-up services. One option is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your C2500. Specifically, we replace the fuel filter and air 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 C2500’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your C2500's mileage and maintenance history can uniquely impact its tune-up 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.

Where Should I Go for My GMC C2500 Tune-Up?

Come to Firestone Complete Auto Care for your next 1999 C2500 engine tune-up. Consult your vehicle’s recommended service schedule from GMC, or make a service appointment if you notice any of these symptoms from your engine: decreased gas mileage, "rough" idling or stalling when stopped, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
