WARNING: This page is about a different car, the 2020 Land Rover Range Rover Velar. However, it is still accessible from the selected car via links, so may be relevant.

SYMPTOM	POSSIBLE CAUSES	ACTION
Coolant loss	Hoses Hose connections Radiator Coolant pump Heater core Gaskets Engine casting cracks Cylinder block core plugs Thermostat Coolant pipes and joins Coolant Degassing lines and degassing point plugs Main radiator and auxiliary radiators Charge air cooler circuit leaks	Complete a visual inspection. If there are no obvious leaks, complete a cooling system pressure test. Rectify any leaks as necessary. If overheating event is suspected perform actions in overheating section after fixing the leak
Overheating	Low/Contaminated coolant Thermostat Viscous fan ECT sensor Restricted air flow over the radiator	Check the coolant level and condition. Complete a cooling system pressure test. Rectify any leaks as necessary. Check the thermostat and rectify as necessary. Check the viscous fan operation, make sure the viscous fan rotates freely. Check for obstructions to the air flow over the radiator. Rectify as necessary. Check Active grille operation
Engine not reaching normal temperature	Thermostat Viscous fan Thermostat Electric fan Fan speed module	Check the thermostat operation. Check the viscous fan operation, make sure the viscous fan is not seized. Rectify as necessary.
Message Centre displays "Coolant Level Low" warning message	Coolant loss Engine coolant level sensor fault Engine coolant level sensor circuit fault	GO to PINPOINT TEST A .
