When should Mitsubishi Montero spark plugs be replaced?

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 should I do if I see leaks under my Montero?

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 some driving habits better for my Mitsubishi Montero 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 Into Your Mitsubishi Montero

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 could be time for a new way of doing things, especially if you want your 2003 Mitsubishi Montero’s engine to last for a long time. Periodic tune-ups can bring more power back to your Montero’s engine. 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 Montero’s long-term engine performance.

Mitsubishi Montero Engine Tune-Up Services

The Firestone Complete Auto Care location in your community offers several Mitsubishi Montero engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your Montero's filters, specifically replacing the air filter and fuel filter. 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 Montero. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your Montero: your vehicle’s maintenance record and mileage can determine which service is best. If you’re not sure what services are the best fit for your car, let us help! Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
