What happens if my GMC C1500 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 do I do if I see a pool of liquid under my GMC C1500?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are some driving habits better for my GMC C1500 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.

At your nearby Firestone Complete Auto Care! Whether you need GMC C1500 service, maintenance, or repairs, our technicians can get the job done.

How often should I clean my GMC C1500 fuel injectors?

Engine Tune-Up for GMC C1500

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1986 GMC C1500. 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*. A second service option replaces the air and fuel filter in your C1500. 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 C1500. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your C1500'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.
