Where is the thermostat located in the Mercedes-Benz GLK200?

The thermostat in the Mercedes-Benz GLK200 is installed in the cylinder head outlet water pipe. Working principle of the automotive thermostat: The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature to ensure the engine operates within an appropriate temperature range, which helps save energy consumption. This is because the engine consumes more fuel at low temperatures and suffers greater damage, including the easy formation of carbon deposits and a series of related issues. Negative effects of improper use of the automotive thermostat: The thermostat must be kept in good working condition; otherwise, it will seriously affect the normal operation of the engine. For example, if the thermostat opens (referring to the main valve of the thermostat) too late or fails to open, it will cause the engine to overheat. If it opens too early, the engine's warm-up time will be prolonged, resulting in the engine temperature being too low.
I once helped a friend repair his Mercedes-Benz GLK200. The thermostat is installed near the cooling system in the engine bay, specifically at the pipe connection near the water pump. There's usually a small round plastic housing where the thermostat is hidden. After opening the hood, you can locate it by following the coolant reservoir's pipes. Last time I worked on it, the thermostat got stuck, causing the engine temperature to skyrocket—it was a real hassle. That's why regular coolant checks are crucial. The location isn't hard to find, but the engine bay is tight, so wear gloves to avoid burns. I recommend working on a cold engine to prevent injuries. If you're not familiar with it, don't force it—better to visit a nearby garage for professional help, saving time and ensuring safety. Regular maintenance of the cooling system can prevent many minor issues.
