Maintenance for Your 1986 Mercedes-Benz 420SEL

What is the recommended maintenance schedule for the 1986 Mercedes-Benz 420SEL?

Here’s Why 1986 Mercedes-Benz 420SEL Scheduled Maintenance Matters

You want your Mercedes-Benz 420SEL to last as long as possible. If you put in the effort to keep up with proper maintenance, you could hit 200,000 miles (or beyond!) in your 420SEL. 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. It’s as easy as following the recommended maintenance schedule that’s been written specifically for your 1986 Mercedes-Benz 420SEL!

The recommended maintenance schedule is put together by Mercedes-Benz, your vehicle manufacturer. Depending on driving conditions and climate in your area (as well as other contributing factors, like your personal travel habits), your car’s scheduled maintenance needs may vary; in most cases, though, recommended maintenance will consist of services like fluid exchanges, filter changes, new brake pads, oil changes, and tire rotations. Keeping up with routine service appointments is a great way to keep your 420SEL running for longer, keep you safer on the road, and maybe even save you the headache of dealing with common 1986 Mercedes-Benz 420SEL problems in the future.

Learn About Vital Maintenance Needs for Your Mercedes-Benz 420SEL

Head to your nearest Firestone Complete Auto Care in your 1986 Mercedes-Benz 420SEL for factory-recommended routine maintenance and an expert technician will begin by performing a Courtesy Check. The Courtesy Check helps us see what we’re working with under the hood, and allows us to alert you to any potential problems before they worsen. Each Courtesy Check includes a free battery test and an inspection of your 420SEL's windshield wiper blades, head and tail lights, filters, fluid levels, tires, and alignment.

Could your 1986 Mercedes-Benz 420SEL be ready for a new battery? Batteries generally need to be replaced every 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. It can be tempting to try and get as much life out of your battery as possible, but it’s smart to check it regularly and replace it before it gets too weak. 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 won't be going anywhere without a strong battery.

Staying on schedule for battery replacements and motor oil changes can support your engine’s overall performance and keep your 1986 Mercedes-Benz 420SEL running newer, longer. To learn how often Mercedes-Benz recommends you have the oil changed in your 1986 420SEL, check out the information table at the beginning of this page. Keep in mind that your oil change interval could be different given your driving style and climate. A Firestone Complete Auto Care technician will be happy to help you determine the best oil change frequency for your car’s needs. We can also answer any questions you have about what type of oil to use for your 1986 Mercedes-Benz 420SEL.

Periodic service to the steering system in your Mercedes-Benz 420SEL can help you keep control of your vehicle at all times (plus, it can make for a smoother ride!). When it comes to steering and suspension, you want to catch small problems before they turn into big (and expensive) ones. You can count on Firestone Complete Auto Care’s trained technicians to inspect this system and, if needed, provide the appropriate Mercedes-Benz 420SEL steering and suspension services. This can include things like power steering fluid replacement, wheel alignment adjustments, replacement of struts and wheel bearings, and ball joint lubrication. To keep your car running at its best, it’s essential to have regular maintenance services on your Mercedes-Benz 420SEL's steering and suspension system.

If you skip recommended Mercedes-Benz 420SEL services, you might find yourself with a hot mess on your hands – quite literally. A damaged A/C system is never fun, and an overheated engine can cause significant issues (like a total car breakdown!). We can help you with all those issues. Our technicians have the knowledge and tools to repair and maintain the heating and cooling systems for your Mercedes-Benz 420SEL’s engine, and we can service your A/C system, too.
