Frequently asked questions

What is the Water Pump (104123459) for?
The Water Pump (104123459) circulates coolant between the cylinder block, head and radiator on the 3.0L AJ20D6 six-cylinder diesel (high-output). Driven off the engine, it maintains coolant flow to carry heat away from the combustion chambers and hold the engine at operating temperature.
What are the signs a water pump is failing?
Common signs of a failing water pump are coolant leaks from the pump housing, a whine or rumble from a worn bearing, and the engine running hot or overheating. On the 3.0 AJ20D6 diesel a failing pump can't maintain coolant flow, so replace it promptly to avoid heat damage to the engine.
Which vehicles does this water pump fit?
This water pump fits the 3.0L AJ20D6 high-output diesel in the New Defender (2020+, L663), Discovery 5 (2017+), New Range Rover (2022+, L460), New Range Rover Sport (2023+, L461) and Range Rover Velar (2017+). Use your VIN to confirm the AJ20D6 high-output diesel before ordering.
Should anything else be replaced with the water pump?
When replacing the water pump it's typically good practice to renew the coolant and inspect the drive belt or timing components that turn it, since access overlaps. On the 3.0 AJ20D6 diesel, refilling with the correct coolant and bleeding the system properly avoids air locks after fitting.
