Where to Add Coolant in a Mercedes-Benz?

[McCora]

Mercedes-Benz coolant is located behind the left headlight in the engine compartment. After starting the engine, let it idle for 2-3 minutes. If the coolant level drops, replenish it until it reaches the "Max" mark. Additional information: 1. Unscrew the radiator cap and open the radiator drain valve to release the coolant. 2. Flushing operation: Insert a rubber hose connected to a water pipe into the radiator filler port. Turn on the tap to allow water to continuously flow through the engine cooling system. During flushing, keep the engine idling until clear water comes out of the radiator. 3. Turn off the water: Close the tap, wait for the cooling system to drain completely, then close the radiator drain valve. 4. Add coolant: Pour coolant into the radiator filler port until full. Unscrew the reservoir cap, add coolant up to the "Max" mark, being careful not to exceed it. 5. Cap and start: Replace and tighten the radiator cap and reservoir cap. Start the engine and let it idle for 2-3 minutes, then open the radiator cap. As air is purged from the system, the coolant level will drop. Replenish coolant until it reaches the "Max" mark again.
