Will it hurt my GMC G3500 to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What should I do if I see leaks under my G3500?

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 hard starts and stops bad for my GMC G3500 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.

How frequently do I need to get my GMC G3500 fuel injectors cleaned?

Tune Into Your GMC G3500

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, particularly if you want to keep your 1986 GMC G3500 in tip-top shape. Regular engine tune-ups can optimize your G3500’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by GMC, you can rest assured you’re investing in your G3500’s long-term engine performance.

Routine Engine Tune-Up Service for Your GMC G3500

The Firestone Complete Auto Care location in your community offers several GMC G3500 engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your G3500. 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 G3500. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your G3500: your vehicle’s maintenance record and mileage can determine which service is best. 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.
