Water Outlet Connection - lower coolant outlet housing in the engine cooling circuit of the 4.4L TDV8 diesel engine.

It bolts to the engine and directs coolant from the cylinder block into the lower coolant hose, and carries the thermostat within the outlet. This is the lower of the two water outlet connections on this engine and is not interchangeable with the upper connection.

Frequently asked questions

What is the Lower Water Outlet Connection used for?

The lower water outlet connection is a coolant housing that routes coolant out of the engine on the 4.4L TDV8 diesel. Also described as a thermostat housing, this lower connection carries coolant in the cooling circuit and is the lower outlet on that engine's cooling layout.

Which vehicles and engine does this fit?

This lower water outlet connection fits the 4.4L TDV8 diesel in the Range Rover L322 2010-2012 (from VIN BA000001), Range Rover L405 2013+ (to VIN FA999999), and Range Rover Sport L494 2014+ (to VIN FA999999). Confirm your engine and VIN, as it's the lower connection specifically.

What's the difference between the lower and upper water outlet?

This is the lower water outlet connection, distinct from the upper outlet on the same 4.4 TDV8 cooling system. They sit at different points in the coolant circuit, so ordering the lower part matters. Check which connection your job needs to avoid fitting the wrong one.

Why does the water outlet connection fail?

The water outlet connection typically fails when the plastic housing cracks or its seal leaks coolant, common on ageing TDV8 cooling parts. Signs usually include coolant pooling near the housing, low coolant level, or a temperature warning, so a leaking connection is replaced to reseal the system.
