When should Ford Explorer spark plugs be replaced?

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 Explorer?

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 Ford Explorer engine than others?

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 Ford Explorer Run Better

Is it tune-up time? 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, particularly if you want to keep your 1991 Ford Explorer in tip-top shape. Routine engine tune-ups can bring power back to your Explorer. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Ford for your vehicle’s tune-up schedule, you can rest assured you’re investing in your Explorer’s long-term engine performance.

Engine Tune-Up for Ford Explorer

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1991 Ford Explorer. 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 Explorer'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 Explorer. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your Explorer: 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 Should I Go for My Ford Explorer Tune-Up?

If you’re looking for 1991 Explorer engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Ford, 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, knocking noises in the engine, or a lit up check engine light on your dashboard.
