1989 Mercedes-Benz 420SEL Maintenance Schedule

You want your Mercedes-Benz 420SEL to last as long as possible. If you put in the effort to keep up with proper maintenance, your 420SEL could be on the road well past the 200,000 mile mark. So, you want to care for your car, but you’re not sure when to get certain services. It can be overwhelming, but fortunately, there’s a resource that takes the guesswork out of routine 420SEL maintenance. Rely on the recommended maintenance schedule that’s been created just for your 1989 Mercedes-Benz 420SEL!

This recommended maintenance schedule is written by the auto manufacturer, Mercedes-Benz themselves. Driving conditions, climate variations, and other variables can affect which scheduled maintenance services you’ll need; however, recommended maintenance usually includes services like oil changes, tire rotations, brake pad replacement, filter changes, and fluid checks and exchanges. Keeping up with routine service appointments is a great way to keep your 420SEL running for longer, increase your vehicle safety, and maybe even save you the headache of dealing with common 1989 Mercedes-Benz 420SEL problems in the future.

Come to Firestone Complete Auto Care for manufacturer-recommended routine maintenance on your 1989 Mercedes-Benz 420SEL and a skilled technician will start the appointment with a Courtesy Check. This Courtesy Check can establish a baseline of what may need to be addressed during your service appointment. During a Courtesy Check, we’ll always check your battery, then we’ll move on to inspect your 420SEL’s head and tail lights, tires, fluid levels, alignment, and windshield wipers.

Maybe it's time to find a new auto battery for your 1989 Mercedes-Benz 420SEL. In general, car batteries only last three to five years. Depending on the climate where you live and your habits while driving, your 420SEL may need a replacement battery sooner. Extremely hot or cold temperatures can take a toll on your Mercedes-Benz 420SEL battery, and so can frequent short drives. While you could wait until your battery fails and you hear the dreaded "click," you're better off replacing it before then! If you keep driving on a battery that can't hold a charge, you run the risk of being stranded when your battery finally gives out (and no one can predict where that might be!). Your Mercedes-Benz 420SEL could quickly go from being a trusty ride to a source of stress in a matter of minutes.

In addition to maintaining a strong battery, investing in regular oil changes can support your engine’s overall performance and keep your 1989 Mercedes-Benz 420SEL running newer, longer.
