Will it hurt my Mercury Mountaineer to drive with old spark plugs?

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 Mountaineer?

Don't ignore puddles of fluid under your Mercury Mountaineer. 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 Mercury Mountaineer engine than others?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

How frequently do I need to get my Mercury Mountaineer fuel injectors cleaned?

Enhance Mercury Mountaineer Performance with a Tune-Up

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you want your 2004 Mercury Mountaineer’s engine to last for a long time. Routine engine tune-ups can bring power back to your Mountaineer. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Mercury's recommendations, you invest in your Mountaineer's long-term health and engine performance.

Mercury Mountaineer Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercury Mountaineer engine tune-up services. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your Mountaineer. 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 Mountaineer’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your Mountaineer can determine what kind of service it 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 Mercury Mountaineer Tune-Up?

Schedule your next 2004 Mountaineer engine tune-up service at Firestone Complete Auto Care. Not sure when you’re due for a tune-up? Use Mercury’s recommended maintenance schedule as a reference point, or schedule an appointment ASAP if you notice any of these signs: 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.
