Mercedes-Benz coolant is located behind the left headlight in the engine compartment. After starting the engine, let it idle for 2 to 3 minutes. If the coolant level drops, you should replenish it until the coolant reaches the Max mark. Coolant is a liquid that prevents freezing and cracking of the radiator and engine cylinder block during cold winter parking. Taking the Mercedes-Benz E300 as an example, its length, width, and height are 5078mm, 1860mm, and 1484mm respectively, with a wheelbase of 3079mm. The front and rear suspensions of the Mercedes-Benz E300 are both multi-link independent suspensions. It is equipped with a 1.5T turbocharged engine, with a maximum power of 135kW and a maximum torque of 280Nm, matched with a 9-speed automatic transmission.

When you can't locate the coolant in your Mercedes, don't panic. It's typically found in a translucent plastic reservoir in the engine bay, labeled 'COOLANT' or similar. Upon opening the hood, you'll usually spot it on the driver's side or near the front center, featuring MIN and MAX level markers - the fluid should sit between them. Always check when the engine is cool to avoid burns from hot components. The coolant prevents engine overheating, with Mercedes-specific variants being pink or blue. Never mix different colors/types when topping up, as this may corrode parts. I make it a habit to check before each service; low levels can trigger warning lights or cooling issues, compromising driving safety. Especially crucial to inspect before summer heat to prevent breakdowns on long trips. Mastering this simple step saves dealership costs and extends your car's lifespan.
