Thermostat

To help regulate the temperature of your engine so that it can run efficiently, there are many different important parts in your Mercedes. The thermostat in your vehicle is a component that is a part of the cooling system working to regulate the flow of coolant to increase or decrease the temperature inside your engine as needed. The thermostat is something that will open or close as needed to help regulate the flow of coolant to your engine or prevent it from getting through. The thermostat is something that will be closed when you're starting the engine because your engine has to warm up enough to allow you to get the car starter properly. When the temperature has reached its limit, the thermostat will open again and let the flow of coolant through to your engine so that your engine doesn't overheat. Thermostats are something that can fail as time passes and might become weak or stuck in an open or closed position. You want to make sure you make a replacement to your thermostat as soon as something like this happens. Find the best OEM thermostats for your Mercedes models here on our site.
