Thermostat

A thermostat is a small device that regulates the flow of coolant going to the radiator of your Benz. When your engine heats up, it allows more coolant through, when it’s cold, it blocks it. If you notice coolant leaking under your vehicle, or if the engine overheats, there may be an issue with your thermostat. There’s no set time on how long a thermostat will last, but you can expect at least 10-years before a problem comes up. When changing it out, an OEM replacement is the safest choice to ensure an optimal level of performance.
