Will it hurt my GMC Sonoma 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 do I do if I see a pool of liquid under my GMC Sonoma?

Don't ignore puddles of fluid under your GMC Sonoma. 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 Sonoma engine than others?

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.

Enhance GMC Sonoma Performance with a Tune-Up

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, especially if you want your 2003 GMC Sonoma’s engine to last for a long time. Periodic tune-ups can bring more power back to your Sonoma’s engine. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by GMC for your vehicle’s tune-up schedule, you invest in your Sonoma's long-term health and engine performance.

GMC Sonoma Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several GMC Sonoma engine tune-up services. One option is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your Sonoma. Specifically, we replace the fuel filter and air filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your Sonoma. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Sonoma'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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
