What happens if my Ford F-350 spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Ford’s recommendations.

What do I do if I see a pool of liquid under my Ford F-350?

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 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 tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you drive a 1986 Ford F-350. Routine engine tune-ups can bring power back to your F-350. 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 get routine engine tune-ups based on Ford's recommendations, you invest in your F-350's long-term health and engine performance.

Ford F-350 Engine Tune-Up Services

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. 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 F-350's filters, specifically replacing the air filter and fuel filter. 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 F-350’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your F-350's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. 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 Ford F-350 Tune-Up?

Come to Firestone Complete Auto Care for your next 1986 F-350 engine tune-up. 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, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
