What happens if my GMC K2500 spark plugs fail?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What should I do if I see leaks under my K2500?

Don't ignore puddles of fluid under your GMC K2500. 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 K2500 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.

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1991 GMC K2500. The standard Firestone Tune-Up is one service option. 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 K2500. 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 K2500. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your K2500's mileage and maintenance history can uniquely impact its tune-up needs.
