LR019736 Engine Coolant Temperature Sensor for Land Rover Discovery 4 LR4 4.0L V6 2010-2011

1. Product Details
This engine coolant temperature sensor is a direct replacement for OEM part number LR019736 (supersedes 4537712). It monitors the temperature of the engine coolant and sends this signal to the engine control unit, which uses the data to manage fuel injection, ignition timing, and cooling fan operation. Manufactured to OEM specifications, this 2-pin sensor is designed for Land Rover Discovery 4 (LR4) models equipped with the 4.0L V6 petrol engine. Note: LR019736 is also cross-referenced for certain other vehicle applications, but the primary Land Rover fitment is Discovery 4 / LR4 4.0L.
