Will it hurt my Geo Prizm to drive with old spark plugs?

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 does a puddle underneath my Geo Prizm mean?

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 Geo Prizm 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.

Enhance Geo Prizm Performance with a Tune-Up

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, especially if you drive a 1990 Geo Prizm. Regular engine tune-ups can optimize your Prizm’s power on the road. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Geo's recommendations, you’re taking vital steps toward keeping your Prizm’s engine running smoother, longer.

Geo Prizm Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Geo Prizm engine tune-up services. One option 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*. The second service focuses on your Prizm's filters, specifically replacing the air filter and fuel filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your Prizm’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Prizm's mileage and maintenance history can uniquely impact its tune-up 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 Geo Prizm Tune-Up?

Come to Firestone Complete Auto Care for your next 1990 Prizm engine tune-up. Follow Geo's recommended maintenance schedule or book an appointment as soon as you notice one of the following: decreased gas mileage, "rough" idling or stalling when stopped, engine knocking, or an illuminated check engine light.
