Mercedes Benz 300D Guides

Facts about the Mercedes Benz 300D

  • For the American market, the Mercedes Benz 300D cars were built with power windows and automatic transmission, but the rest weren't built with these features. They were also equipped with 180 PS (130kW and 180 horsepower) at 5500 rpm. As an option, power steering, power brakes, and Artic-Kar air conditioning were added.

  • There was a total of 3,077 300D models that was manufactured in March 1962, along with 65 300D-based Cabriolet Ds that were special orders. After some time, the model was replaced as the Mercedes Benz flagship by the 600 Pullman Grand Mercedes.

  • The first Mercedes Benz 300D was introduced to the American public in 1975. The life of the 300D began by the carmakers installing newly improved 3-liter five-cylinder naturally aspirated diesel engine 617.910 in the W115 chassis four-cylinder Mercedes Benz 240D diesel.

  • The evolution of the W123 chassis was continuously added in the production of the Mercedes Benz 300D Turbo Diesel in 1982. It was a 3-liter five-cylinder turbocharged engine and was first introduced in 1978. It was also first offered in the American market for the Mercedes Benz 300.

  • Throughout the 1950s, the Mercedes Benz 300 types, which included the 300D, was the car company's largest and most prominent models. It had that exclusive, luxurious, elegant, and powerful impression, which the owners loved and felt proud of.

  • The American market surely loved the appearance of the Mercedes Benz 300D; it was luxurious but also had a sporty touch. The lubrication system of the vehicle does not use grease, but uses oil instead. It was also built with a hardtop, which was elegant according to the buyers.

  • The diesel-powered Mercedes Benz 300D was part of the straight vegetable oil movement. In fact, there was a recent study in the Houston Press that covered the story of a biochemistry student who converted the 300D car to function on SVO. Study shows that used 1985 Mercedes Benz diesel power plants are famous for being imperishable when converted.

  • The Mercedes Benz 300D had an additional 4 inches of wheelbase, which gave the passengers the opportunity to have more rear legroom. This also made the vehicle a true limousine, which then became the competitor of the Rolls-Royce Silver Cloud.

Usual Problems of the Mercedes Benz 300D

The Mercedes Benz 300D was a prestigious car that was introduced back in August 1957. Even though it was built decades back, it's not a surprise that this can still be seen being driven on the road by some proud owners. Just like old cars, it's unavoidable for this to also experience problems, considering that it was built in the late 1950s. Here are some of the common problems that were reported by the owners so that others can also be aware of the issues that the 300D experiences.


Problems with shifting gears

This kind of issue is very dangerous. Basically, it's a transmission problem and if not attended to right away, the safety of the driver and the passengers could be at risk. Some of the problems reported was that the 300D performed well, unless it goes over 45 mph-the vehicle will refuse to switch to 3rd gear. The best thing that an owner could do is to take this to a shop and to get expert advice from a trusted mechanic.


Idles rough

This kind of problem is not very dangerous because it won't greatly jeopardize the performance of the vehicle. But though this is a minor issue, it must not be overlooked. Generally, Mercedes is equipped with a vacuum system to work the power locks, cruise control, shutoff system for the car engine, and many others. Rough idling can be due to worn rubber, which dries out and loses its vacuum. Have this inspected by a mechanic so that worse engine problems won't occur.


Issue with engine shutoff

This is another engine problem, but one that must not be overlooked. If the engine doesn't shut off, then this could be pretty bad, and it could jeopardize the performance of the Mercedes Benz 300D.


Other problems

Other problems that usually occur on the Mercedes Benz 300D include worn seat springs that can cause the car seats to lean or sag. For great comfort and focus on the road, the spring should be replaced. Also, once there are knocking noises that are coming from the front end, this is due to cracked strut tower bushings.

FAQs—Mercedes Benz 300D

A tire on my Mercedes Benz 300D seems to show early signs of wear. It is strange because I always make sure that my tires are maintained regularly. Why does it happen?

Premature tire wear is caused by several factors other than lack of tire maintenance. The ball joints may be damaged already. Cracked or worn lower control arm bushings can also be a culprit, as they can lead to movements at the control arm pivot point that are too much to bear for the tires. This often results in early and irregular tire wear. Before the damage gets worse, make sure to replace any worn ball joint and lower control arm, including the bushings.

There is an excessive free play in my 300D's steering assembly. What is causing it and how do I deal with it?

Premature wear on the steering box, idler arm, tie rod ends, or drag link parts of the steering linkage may be causing the excessive play. Inspect these parts and replace any damaged parts to significantly reduce the steering play.

How do I convert the air-conditioning system of my 300D from R12 to R134? Is it even possible?

Yes, you can convert to R134 with the right tools and following procedures properly. Converting to R134 makes a lot more sense than buying R12 Freon for your AC system, which is pricey and hard to find. R134 Freon is easier to find online and is relatively cheaper than R12 Freon. Before you start, gather the tools needed for the job: the R134 Freon, R134 retrofit kit, vacuum pump, manifold gauges, and refrigerant recovery machine. And of course, get ready with your Mercedes Benz 300D service manual for the detailed steps on R134 conversion.

The first step is to take out the old R12 Freon from the AC system. You can do this if you have a certification from the U.S. Environmental Protection Agency (EPA). Otherwise, have the R12 Freon removed by an EPA-certified mechanic using a refrigerant recovery machine. It is because it is illegal to remove R12 Freon from a vehicle without this certification from EPA. The next step is to open the engine compartment to access the high- and low-pressure couplings on the AC system, where you will have to screw the new fittings on. Then put the manifold gauges on the hood latch and attach the high- and low- side tubes to their corresponding ports on your vehicle. Hook a vacuum pump to the neutral port and create a vacuum in the AC system. This will take one or two hours to complete. Once it is done, detach the vacuum pump. Start your 300D and switch on the AC compressor. Refer to your service manual for the specs of your 300D's AC system; this will help you know the amount of coolant you need to add. Attach the container of R134 Freon to the neutral hose on the manifold gauges. Lastly, open the low-side port on the gauges. Opening the high-side port may be dangerous because it is highly pressurized. Now, check the air coming out of the AC vents. If it is not cold, inspect the AC compressor for any leaks.

The Luxury and Legacy of Mercedes Benz 300D

Mercedes Benz is recognized worldwide for producing breathtaking luxury vehicles that have a mighty powerhouse under their hoods, and the 300 line is no exception. Considered as the largest and most prestigious lineup in the 1950s, the 300 series was elegant, impressive, and superior in all levels. These vehicles, classified as touring cars, sported several luxury features that were specially made for politicians and businessmen. One of the most popular and enduring models of the 300 series was the Mercedes Benz 300D. This model exhibited all the sterling qualities and high-end features Mercedes Benz vehicles were famous for, creating a legacy that continues until today.

1957: The birth of a legacy

The Mercedes Benz 300D was unveiled in August 1957, following the 300C lineup and creating a legacy of its own. It featured a longer wheelbase, an innovative hardtop design, and an advanced fuel injection system. Considered as a modern-day phaeton and parade car, the 300D was an elegant limousine with a stunning design and remarkable features that rivaled those of the Rolls-Royce Silver Cloud. Removable rear quarter lights, Artic-Kar airconditioning system, and power steering and braking mechanisms are just some of the features integrated into the 300D, putting it ahead of the other automobiles produced during its time. A revolutionary Bosch fuel injection system powered the 300D and produced 180 HP at 5,500 RPM, a rather impressive power output for a diesel-powered engine. This staggering statistic drove engineers and scientists to produce faster and more powerful internal combustion engines that could compete with the 300D’s diesel-powered unit.

1982: The legacy continues

In 1982, the 300D once again raised the bar for all diesel-powered vehicles with a highly efficient turbocharged engine that delivered superior performance on the road. With this upgrade, Mercedes Benz claimed that the 300D outperformed all other diesel-powered vehicles in the world. Twenty seven years later, 300Ds are still rolling on the road and providing reliable service to their owners. These legendary Mercedes Benz models were able to outlive the other diesel-powered vehicles produced during their time. The 300D was indeed a remarkable addition to Mercedes Benz’s three-liter lineup that includes some of the greatest 300 series models produced during the ‘50s era. It was at par with the 300S, 300SL, and 300SLR, all sporting and racing legends in their own right. Even without a notable race heritage, the 300D is still a stellar contribution to the Mercedes Benz legacy.
