When should Chrysler 300M spark plugs be replaced?

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 Chrysler’s recommendations.

What should I do if I see leaks under my 300M?

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 300M 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.

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, particularly if you want to keep your 1999 Chrysler 300M in tip-top shape. Routine engine tune-ups can bring power back to your 300M. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions.

Engine Tune-Up for Chrysler 300M

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Chrysler 300M engine tune-up services. 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 300M. 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 300M's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your 300M: your vehicle’s maintenance record and mileage can determine which service is best. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
