When should GMC K3500 spark plugs be replaced?

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?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

Are some driving habits better for my GMC K3500 engine than others?

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.

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, particularly if you want to keep your 1986 GMC K3500 in tip-top shape. Regular engine tune-ups can optimize your K3500’s power on the road. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy.

Engine Tune-Up for GMC K3500

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to GMC K3500 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 K3500. Specifically, we replace the fuel filter and air filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your K3500's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your K3500 can determine what kind of service it needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
