What happens if my Toyota Avalon spark plugs fail?

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 do I do if I see a pool of liquid under my Toyota Avalon?

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 Toyota Avalon 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 Toyota Avalon Run Better

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, it could be time for a new way of doing things, especially if you want your 2003 Toyota Avalon’s engine to last for a long time. Regular engine tune-ups can optimize your Avalon’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 Toyota's recommendations, you’re taking vital steps toward keeping your Avalon’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Toyota Avalon

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2003 Toyota Avalon. 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*. The second service focuses on your Avalon'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 Avalon’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Avalon: 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.

Where Should I Go for My Toyota Avalon Tune-Up?

Come to Firestone Complete Auto Care for your next 2003 Avalon engine tune-up. Follow Toyota's recommended maintenance schedule or book an appointment as soon as you notice one of the following: 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.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.
