What happens if my Mitsubishi Diamante 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 should I do if I see leaks under my Diamante?

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.

What do hard starts and stops do to my Diamante 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.

Tune-Ups to Help Your Mitsubishi Diamante Run Better

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, particularly if you want to keep your 2004 Mitsubishi Diamante in tip-top shape. Regular engine tune-ups can optimize your Diamante’s power on the road. Tune-ups help your engine start smoothly and run efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you take your car for regular engine tune-ups as recommended by Mitsubishi, you can rest assured you’re investing in your Diamante’s long-term engine performance.

Mitsubishi Diamante Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mitsubishi Diamante engine tune-up services. The standard Firestone Tune-Up is one service option. 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 Diamante. 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 Diamante’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your Diamante: 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. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where Should I Go for My Mitsubishi Diamante Tune-Up?

If you’re looking for 2004 Diamante engine tune-up services, head to Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Mitsubishi’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
