What happens if my Toyota Sienna 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 does a puddle underneath my Toyota Sienna mean?

Don't ignore puddles of fluid under your Toyota Sienna. 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 Toyota Sienna 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 Sienna Run Better

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, especially if you drive a 1999 Toyota Sienna. Routine engine tune-ups can bring power back to your Sienna. They're designed to help your engine start easier and run more 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 Sienna’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Toyota Sienna

The Firestone Complete Auto Care location in your community offers several Toyota Sienna engine tune-up services. 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*. Another service option pays special attention to the filters in your Sienna. Specifically, we replace the fuel filter and air 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 Sienna’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 Sienna: 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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Toyota Sienna Tune-Up

If you’re looking for 1999 Sienna engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Toyota, 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, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.

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