Frequently asked questions

What does the auxiliary water pump do on the fuel-fired heater circuit?
It's an electric coolant pump that circulates coolant through the fuel-fired booster heater's heat exchanger, delivering heat to the cabin matrix while the engine is cold or switched off. It only runs while the heater unit is active.
Where is the auxiliary water pump located in the cooling system?
It sits in a dedicated branch of the coolant circuit connected to the fuel-fired pre-heater, working alongside the engine-driven water pump rather than replacing it. It's controlled directly by the heater unit, not the main engine ECU.
Which models use this Pierburg auxiliary water pump?
This OEM Pierburg pump fits the Discovery 3 (2005-2009), Discovery 4 (2010-2016), Discovery 5, and Range Rover Sport L320 (2005-2013) and L494 (2014-2022) fitted with a fuel-fired auxiliary heater.
Why does the auxiliary water pump fail on these vehicles?
These pumps typically fail from bearing wear or impeller seizure after years of intermittent running, especially if the heater circuit has trapped air or low coolant. A failed pump usually shows up as reduced auxiliary heat output or a fault code for the pre-heater system.
