OEM Mercedes and Porsche Thermostats

Refine Results

There are many important parts in your Mercedes that work to regulate the temperature of your engine so that it can run efficiently. The thermostat is a component in the cooling system that regulates the flow of coolant to increase or decrease the temperature of the engine as needed. The thermostat opens or closes as needed to send coolant to the engine or block it from entering. The thermostat will be closed when you're first starting the engine because the engine has to get warmed up enough to get it operating properly. Once the temperature has been reached, your thermostat will open and allow the flow of coolant through to your radiator and engine. Thermostats can fail over time and become weak or stuck in an open or closed position. This is not good. You need to ensure you make a replacement right away when this occurs. You might experience overheating of the engine - you might notice the thermostat jumping to hot soon after starting the car. On the other hand, your engine might have problems getting warmed up enough. Ensure you get an OEM replacement thermostat for your Mercedes here at German Auto Parts Source.
