Frequently asked questions

What is the LR105974LR thermostat used for?
The LR105974LR thermostat is the engine cooling thermostat for the 2.0L Ingenium diesel (AJ200D). It regulates coolant flow to warm the engine up quickly, then opens to let coolant reach the radiator as temperature rises.
Which models use this AJ200D thermostat?
This thermostat fits the 2.0L Ingenium diesel (AJ200D) in Discovery 5, Defender 2020+ (L663, Nitra build from VIN K2000001), Range Rover Sport L494 and Range Rover Velar. Confirm your engine is the 2.0 Ingenium diesel.
What are the signs the thermostat needs replacing?
