Where is the coolant located in a Mercedes-Benz?

[DiRonan]

Coolant is located in a small pink-colored reservoir on the left side of the engine compartment. Functions of the cooling system: To provide proper cooling for the operating engine, maintaining it within the optimal temperature range. Engine cooling must be moderate - insufficient cooling will reduce engine power, degrade engine oil, and weaken mechanical components due to overheating; excessive cooling causes excessive heat dissipation, reducing engine performance and fuel economy while increasing oil viscosity and friction between moving parts, leading to accelerated wear. Precautions for coolant usage: Prevent coolant leakage, as leaks not only cause coolant loss but severe leaks may dilute engine oil and cause lubrication system failures; avoid skin contact; maintain year-round coolant usage and ensure continuity of coolant application.
