How much coolant should be added to a Mercedes GLK?
3 Answers
Mercedes GLK requires approximately 6 liters of coolant. Method for adding coolant: Park the car on a level and solid ground, wait for the engine to fully cool down, open the engine hood, and locate the purple oval-shaped coolant reservoir on the left side. When the engine is cold, check the coolant level via the markings on the side of the expansion tank. When refilling coolant, use a suitable cloth to cover the expansion tank cap to prevent burns from hot coolant or steam on your hands and arms. Precautions for using coolant: Do not open the coolant reservoir cap or drain valve immediately after driving, as the temperature of the coolant or water is very high at this time to avoid burns. The effective service life of coolant is generally two years. Replace it when expired or if the coolant appears dirty. During replacement, ensure all old coolant is completely removed and the reservoir is thoroughly cleaned.
I've been driving a Mercedes GLK for several years and have encountered coolant issues. You need to be careful when adding coolant. Typically, the GLK requires about 5-7 liters, but the exact amount depends on your model year and engine type. Older models might need a bit more, while newer ones require less. I usually check the coolant level near the MAX line when the engine is cold, then add it slowly. Don't fill it up all at once—leave some room for the system to vent. Make sure to use Mercedes-approved blue coolant that meets the MB 325.0 standard, or else it could corrode the pipes. Regularly checking the coolant level is important; I always take a look during maintenance. If there's a leak or the coolant degrades, engine overheating can become a serious issue, leading to higher repair costs. After adding coolant, I recommend running the engine for a few minutes to circulate the fluid and ensure everything works properly. In short, always refer to the manual first—don’t skip checking the details.
I'm a car enthusiast, and according to my research, the coolant capacity of the Mercedes-Benz GLK varies by model. The GLK250 or 350 typically falls within the range of 5-8 liters, for example, the 250 diesel version holds about 6 liters. Last time I refilled it, I first drained all the old fluid completely, then poured new coolant up to the MAX mark, being careful not to overfill to avoid spillage. It's crucial to choose a coolant that matches the original factory specifications to prevent chemical reactions that could damage the radiator. By the way, the cooling system relies on fluid circulation to dissipate heat. Adding too much or too little coolant can affect the water pump's efficiency, causing the engine's water temperature to skyrocket. I recommend using a mobile app to check the manual or forums for reliable data. Before adding coolant, inspect the hoses for any cracks to prevent minor issues from turning into major repairs.
