Subaru 3-Pin Coolant Temperature Sensor Connector Kit

Is your temp gauge acting erratic or is your Subaru throwing cooling system codes? This TS 090 Sealed Series 3-pin connector is the factory-spec replacement for the Coolant Temperature Sensor.

Located in a high-heat area of the engine block, the original plastic housing often becomes brittle and the locking tab snaps off, leading to loose connections. This kit allows you to completely refresh the plug with new terminals and seals, ensuring your ECU gets the precise, high-fidelity signal it needs to keep your engine running at the right temperature.
