What happens if my Dodge Diplomat 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 Dodge’s recommendations.

What does a puddle underneath my Dodge Diplomat mean?

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.

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.

Tune-Ups to Help Your Dodge Diplomat Run Better

Is it tune-up time? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you want your 1989 Dodge Diplomat’s engine to last for a long time. Periodic tune-ups can bring more power back to your Diplomat’s engine. 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 can rest assured you’re investing in your Diplomat’s long-term engine performance.

Dodge Diplomat Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1989 Dodge Diplomat. One option 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*. Another service option pays special attention to the filters in your Diplomat. Specifically, we replace the fuel filter and air 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 Diplomat’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your Diplomat'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. 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 Dodge Diplomat Tune-Up?
