Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Connecting Tube running from the thermostat housing to the EGR cooler, part of the engine coolant circuit on the 2.0L Ingenium petrol engine and its PHEV derivative.

The tube carries engine coolant to the EGR cooler, which reduces the temperature of recirculated exhaust gas before it re-enters the intake. Coolant flow through this line is what allows the EGR cooler to do its work, so a restricted or leaking tube affects both EGR performance and cooling system integrity.

Because the tube sits in a congested area between the thermostat housing and the exhaust side of the engine, coolant loss from it is often first noticed as unexplained level drop rather than a visible external leak.

Frequently asked questions

What is the LR181890LR connecting tube and what does it do?
The LR181890LR is the coolant connecting tube from the thermostat housing to the EGR cooler on the 2.0L Ingenium petrol engine and its PHEV derivative, used in the New Defender L663, Discovery 5 and Range Rover Velar. It carries coolant to the EGR cooler, which cools recirculated exhaust gas before the intake.
How does a fault in this tube show up?
A restricted or leaking connecting tube affects both EGR performance and cooling integrity. Because it sits in a congested area between the thermostat housing and the exhaust side, coolant loss is often first noticed as an unexplained level drop rather than a visible external leak.
Which engines does this tube fit?
This tube fits the 2.0L Ingenium petrol (AJ200) and 2.0L PHEV only. Diesel and other petrol engines route coolant differently and use different pipes, so confirm your engine is a 2.0L Ingenium petrol or PHEV before ordering.
