Part number: MER-0055456324 is a new, unused Genuine Mercedes engine coolant temperature sensor. In our race for ever better fuel economy, sensors play a large part in optimizing an engine's performance, be it speed or fuel economy. The engine coolant temperature sensor monitors the coolant's temperature and can help in triggering the engine cooling fan AND can provide important data to the car's computer so it can make fuel mix adjustments, timing adjustments, the list goes on. In short if this sensor is not working properly, expect to get poor engine performance while also running the risk of overheating. This is an important sensor!
