Installation Notes and Tips

Confirm the connector style and terminal layout before installation. Inspect the coolant reservoir and harness connector for corrosion, damaged pins, or coolant residue that could affect sensor operation. Verify the application by year, make, and model before ordering, especially on Land Rover Range Rover and Discovery platforms with multiple cooling-system configurations.
