Will it hurt my Dodge D350 to drive with old spark plugs?

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 D350?

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 Dodge D350 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 Dodge D350 fuel injectors cleaned?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Enhance Dodge D350 Performance with a Tune-Up

Is your engine overdue for a tune-up? 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 drive a 1989 Dodge D350. Routine engine tune-ups can bring power back to your D350. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Dodge for your vehicle’s tune-up schedule, you invest in your D350's long-term health and engine performance.

Dodge D350 Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1989 Dodge D350. One option 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 D350. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your D350's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your D350: 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. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
