Ensure accurate engine temperature monitoring with this coolant temperature sensor for Defender, Discovery I, and Range Rover models. This sensor, often referred to as the water temperature transducer, sends critical temperature data to the ECU for proper fuel delivery and engine management.

A failing coolant temperature sensor can cause poor fuel economy, hard starting, incorrect gauge readings, or engine performance issues. On GEMS-equipped vehicles, accurate temperature input is essential for proper EFI operation and overall drivability.

This sensor installs directly into the cooling system and connects to the factory wiring harness. Available in OEM Lucas for factory-correct performance or a quality replacement option from Britpart/Allmakes, giving you flexibility based on your needs and budget.
