Mercedes Benz 450SEL Guides

FAQs—Mercedes Benz 450SEL

Two weeks ago, I noticed some problems in shifting while driving my Mercedes Benz 450SEL. So, I topped up the transmission fluid. When I was replenishing it, the fluid was all over the floor. Therefore, I'm positive that there is a leak; I just have to confirm where it is coming from. Do you have any ideas on how to fix this?

Transmission leaks are commonly caused by a damaged or loose pan gasket or worn out fluid lines and seals. The leak can also come from a faulty torque converter. To fix your leakage problem, you must first identify the source of the leak. A great way to do that is to use a transmission fluid dye. This dye will make the fluid glow and will help you determine where the leak is coming from. You would also need a UV light flashlight for this task. First, top up the reservoir again and add 1 oz. of the dye into the fluid. Start your car and drive and wait for the fluid to start leaking. Come back and check with your UV light and find the flowing leak. Once you have seen the source, determine if the problem can be fixed or have to undergo expert repair. Loose pans and fluid lines are relatively simple to fix. However, if you notice that the amount of leak is already too large and that you cannot fix the problem, then you better take your 450SEL to the repair shop.

For the past three months, my Mercedes Benz 450SEL has suffered from two instances of overheating while in the middle of traffic. I have checked the coolant and the amount is still okay and is not leaking. What are the other possible causes, and how do I prevent engine overheating?

Aside from the coolant being too low, other causes of overheating are a damaged fan belt, a faulty thermostat or a broken radiator. It could also be that the car's internal fan is not working properly. Therefore, check all of these and determine whether parts need to be fixed or replaced. If you have time and money to spare, take your car to the mechanic. Also, using the brakes too much can also cause engine to work harder and overheat. Keep this in mind and aim to always drive at a steady pace. Always keep a bottle of spare coolant in the car just in case; but never open the radiator cap while the engine is still hot.

I recently purchased my Mercedes Benz 450SEL from a used car shop. Following the suggestion of a local mechanic, I changed the serpentine and timing belts since the original ones were already badly worn out. What should I remember to keep the belts preserved and intact for the years ahead?

It is good that you have decided to replace the belts. The serpentine belt, in particular, runs through different parts of the engine and is responsible for powering the power steering, the air conditioner, the alternator and the power steering pump. These car engine parts are integrated to each other and everything works as a whole. Thus, giving due regular maintenance to all the engine systems will also contribute in preserving the good condition of your new belts. Also make sure that the belts are properly placed and not misaligned, since slips like this can cause unnecessary stress on the rubber. Though a lot of people use it to quiet squeaky belts, belt dressing solutions are not really recommended. Belt dressing solutions comes in oils or solvents that lubricate and eliminate squeaking belts. However, once it dries out the rubber may actually become more susceptible to cracking.

From the First S-Class Model—Mercedes Benz 450SEL

A new series of luxury sedans was officially launched in the market in 1972. The Mercedes Benz S-Class was unveiled with the release of the W116. The series then reigned as a flagship model for Benz for more than 50 years, with numerous generations of S-Class sedans and some coupe models called the SEC and later the S-Coupe. It has become a top-seller among luxury sedans in the world. The series has been known for its many innovations, including drivetrain technologies, safety systems, and interior features. It is an award-winning series that received various recognitions such as the J.D. Power Sales Satisfaction Index (1987-1990), Car of the Year by Wheels Magazine (1981-1999), and Safest Passenger Car of the Year by U.S. Highway Loss Data Institute (1988-1989). It was also named Best Luxury Car by What Car? (seven times) and Luxury Car of the Year by Fleet News (five times. From the first S-Class in the ‘70s, various incarnations came out over the years. Under the W116 were several versions, including the Mercedes Benz 450SEL.

1973-1980: The reign of the W116 and introduction of the 450SEL

A year after the W108/109 was launched, the development of the new S-Class generation started in 1966. The design of the new series was eventually finalized in 1969. The more modern design adopted new corporate styling at that time, which would be featured until 1993. The series was designed with a bit more masculine lines that complemented its elegant style and sporty look. The design quite resembled that of the R107 SL-Class roadster.

The W116, the first S-Class, was unveiled in 1972. Initially, it used two versions of the M110 engine, a straight-six engine with 2,746 cc displacement. Under this model was the 280S, featuring a Solex carburetor, and the 280SE with the Bosch D-Jetronic injection system. Also under the model range was the 350SE with an M116 engine, a V8 with 3,499 cc displacement. The lineup eventually included the 450SE and 450SEL. The Mercedes Benz 450 SEL had a 100mm longer body. Both models came equipped with the M117 engine, a V8 with 4,520 cc displacement.

In 1975, a high-performance version of the W116 was introduced. This was called the 450SEL 6.9. It was based on the W116 chassis long-wheelbase version. The limited-production high-performance model was the first production car to be equipped with an optional ABS system (an electronic four-wheel multi-channel anti-lock braking system) from 1978 onwards. It also featured a self-leveling hydropneumatic suspension and a larger engine. It was known as the 6.9, distinguishing it from the basic Mercedes Benz 450SEL model.

The W116 was available throughout Europe and other markets such as Asia, the Middle East, Australia, Africa, and the Americas. Production totaled to 473, 035 units. About 59,578 Mercedes Benz 450SEL sedans were built from 1973 to 1980. The first S-Class model was eventually replaced by the W126 S-Class.
