Will it hurt my Dodge Diplomat 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 do I do if I see a pool of liquid under my Dodge Diplomat?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

What do hard starts and stops do to my Diplomat engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

How frequently do I need to get my Dodge Diplomat fuel injectors cleaned?

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune-Ups to Help Your Dodge Diplomat Run Better

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, particularly if you want to keep your 1986 Dodge Diplomat in tip-top shape. Periodic tune-ups can bring more power back to your Diplomat’s engine. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Dodge's recommendations, you’re taking vital steps toward keeping your Diplomat’s engine running smoother, longer.

Dodge Diplomat Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1986 Dodge Diplomat. 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*. Another service option pays special attention to the filters in your Diplomat. Specifically, we replace the fuel filter and air filter. 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 Diplomat's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your Diplomat's mileage and maintenance history can uniquely impact its tune-up needs. 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.

Where to Get a Dodge Diplomat Tune-Up

Come to Firestone Complete Auto Care for your next 1986 Diplomat engine tune-up. Follow Dodge's recommended maintenance schedule or book an appointment as soon as you notice one of the following: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.
