An OEM coolant temperature sensor is a genuine Subaru part that monitors the engine’s coolant temperature. It sends this information to the engine control unit (ECU) to regulate fuel delivery, ignition timing, and cooling fan operation, ensuring optimal engine performance and preventing overheating.

It’s a direct replacement for your factory sensor, maintaining accurate readings and proper engine function.
