Will it hurt my GMC C1500 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 should I do if I see leaks under my 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 hard starts and stops bad for my GMC C1500 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.

How frequently do the fuel injectors in my GMC C1500 need to be cleaned?

Enhance GMC C1500 Performance with a Tune-Up

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you drive a 1989 GMC C1500. Regular engine tune-ups can optimize your C1500’s power on the road. They're designed to help your engine start easier and run more 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 can rest assured you’re investing in your C1500’s long-term engine performance.

Engine Tune-Up for GMC C1500

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1989 GMC C1500. 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*. A second service option replaces the air and fuel filter in your C1500. 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 C1500's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your C1500 can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where Should I Go for My GMC C1500 Tune-Up?

Schedule your next 1989 C1500 engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from GMC, or make a service appointment if you notice any of these symptoms from your engine: stalling or shaky idling when you’re stopped, diminished fuel economy, knocking noises in the engine, or a lit up check engine light on your dashboard.
