Where does Mercedes-Benz prompt to add coolant?
2 Answers
Mercedes-Benz prompts to add coolant behind the left headlight in the engine compartment. The steps 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 water pipe into the radiator filler port, turn on the tap, and let tap water continuously flow through the engine cooling system. Keep the engine idling during the flushing operation until clear water comes out of the radiator; 3. Turn off the tap, wait until the water in the cooling system is completely drained, then close the radiator drain valve; 4. Unscrew the reservoir cap, add antifreeze up to the Max mark, being careful not to exceed it.
I've been driving a Mercedes for several years and have encountered the coolant warning light. The location is in the engine compartment. Open the front hood and look near the windshield—you'll see a translucent plastic tank marked 'coolant' or with a wavy symbol. That's the coolant reservoir. Always wait for the engine to cool down before operating, as high-temperature steam can cause burns. When adding coolant, don't use tap water—use Mercedes-recommended antifreeze and slowly pour it up to the 'max' mark. The warning light usually indicates low fluid level, but after topping up, check for leaks—look for water stains under the car or loose pipe connections. If the warning appears frequently, you may need professional inspection of the water pump or thermostat to prevent small issues from becoming major problems. Safety first—never open the cap when the engine is hot.
