When should Ford F-350 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 does a puddle underneath my Ford F-350 mean?

Are some driving habits better for my Ford F-350 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.

Tune-Ups to Help Your Ford F-350 Run Better

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you want your 1991 Ford F-350’s engine to last for a long time. Routine engine tune-ups can bring power back to your F-350. Tune-ups help your engine start smoothly and run efficiently, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Ford, you invest in your F-350's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Ford F-350

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Ford F-350 engine tune-up services. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your F-350. 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 F-350. This can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your F-350 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 to Get a Tune-Up for Your Ford F-350

If you’re looking for 1991 F-350 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: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.
