Good To Know

Q: Why does this sensor have four pins instead of two? A: The four-pin design allows the sensor to send temperature data to both the engine control unit and the dashboard gauge simultaneously.

Q: Should I drain the coolant before replacing this sensor? A: It is recommended to partially drain the coolant or work quickly on a cold engine to minimize fluid loss during swap.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
