Where is the coolant level mark on a Mercedes-Benz?
1 Answers
The coolant level mark on a Mercedes-Benz is located behind the left headlight in the engine compartment. Usage of coolant in Mercedes-Benz S350: After starting the engine, let it idle for 2-3 minutes. If the coolant level drops, replenish it until it reaches the "Max" mark. Unscrew the radiator cap, open the radiator drain valve, and drain the coolant. Insert a rubber hose connected to a tap into the radiator filler port, turn on the tap, and let tap water continuously flow through the engine cooling system. Precautions for use: Coolant should be used year-round. For traditional engines, the normal operating temperature range for coolant is 80°C to 90°C. However, for electronically controlled engines, due to their high speed, high compression ratio, and high power characteristics, they experience greater mechanical and thermal loads and higher friction heat. Therefore, the normal operating temperature for coolant has been increased to 95°C to 105°C. This differs from the traditional view of "normal coolant temperature" for conventional engines, requiring a shift in perception. Additionally, it is important to maintain continuous use of coolant. The notion of using coolant only in winter is incorrect, as it overlooks the anti-corrosion, anti-boiling, and anti-scaling functions of coolant, focusing solely on its anti-freeze properties. When selecting coolant, its freezing point should be about 10°C lower than the lowest environmental temperature.
