Will it hurt my Pontiac Grand Prix 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 Pontiac’s recommendations.

What should I do if I see leaks under my Grand Prix?

Don't ignore puddles of fluid under your Pontiac Grand Prix. 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.

Are some driving habits better for my Pontiac Grand Prix engine than others?

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.

Tune-Ups to Help Your Pontiac Grand Prix Run Better

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 2003 Pontiac Grand Prix. Regular engine tune-ups can optimize your Grand Prix’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 get routine engine tune-ups based on Pontiac's recommendations, you’re taking vital steps toward keeping your Grand Prix’s engine running smoother, longer.

Engine Tune-Up for Pontiac Grand Prix

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2003 Pontiac Grand Prix. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your Grand Prix. 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 Grand Prix. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your Grand Prix: your vehicle’s maintenance record and mileage can determine which service is best. 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.
