Where is the location to add antifreeze in a Mercedes-Benz?

In a Mercedes-Benz, the antifreeze is added on the left side of the engine compartment, behind the headlight. The steps to add antifreeze are as follows: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the antifreeze. 2. Insert a rubber hose connected to a tap into the radiator filler port and turn on the tap. 3. Once the cooling system is completely drained, close the radiator drain valve. 4. Replace the radiator cap and the reservoir cap, and tighten them. Precautions for using antifreeze are as follows: 1. Mixing antifreeze with water can damage the engine. 2. Avoid mixing different types of antifreeze together. 3. Remember to check the antifreeze regularly.
When I first got into Mercedes-Benz cars, I was also curious about where to add the antifreeze. Actually, the location is quite simple—it's under the car's hood. After opening the hood, look for the plastic reservoir labeled 'Coolant' or 'COOLANT.' It's usually white or translucent and located on the passenger side, near the windshield. I recommend adding it only when the engine is cool to avoid burns or high system pressure. Remember to use the antifreeze model recommended by Mercedes-Benz and avoid mixing different types to prevent system corrosion. Checking the fluid level is crucial; it should be between the 'min' and 'max' lines. Too low, and the engine may overheat; too high, and it may overflow. My personal habit is to check it every two months, especially before long trips. After topping up, tighten the cap to ensure a seal and prevent leaks. Antifreeze isn't just for freezing protection—it also prevents engine parts from rusting, so don't overlook its maintenance.
Having driven for decades, the coolant refill point for Mercedes-Benz is in the expansion tank under the hood. Lift the hood and look for the plastic tank marked with an icon or 'Coolant' label—it's easy to spot. The exact location varies slightly by model; for example, the C-Class might have it on the left side, while the S-Class positions it more centrally, but it's generally in a visible spot. I always advise younger drivers to let the car cool for at least half an hour before adding coolant and to simply check with a fingertip to ensure it's not scalding hot. Never use tap water as a substitute—mix dedicated antifreeze with distilled water in the ratio specified in the manual. Both overfilling and underfilling can impair cooling performance. I prefer checking the level on a flat surface when the car is stationary for accurate reading. Regularly replacing the coolant is crucial—typically every two years—to prolong the engine's lifespan.
