Temperature Sensor | 251 919 501D

This temperature sensor (OEM 251 919 501D) sends the signal to your dashboard's temperature gauge, so you know what temperature your engine is running at. The part is located in the cylinder head and directly measures the coolant temperature. After decades, the sensor can react slowly or fail completely, resulting in an unreliable reading. Combine this with a new temperature gauge for a complete upgrade of your temperature monitoring.
