Water Connection for the turbocharger coolant feed, lower position, in the turbocharger lubrication and cooling circuit of the 3.0L AJ20P6 Ingenium petrol engine, including PHEV applications.

The connection forms the lower leg of the coolant feed between the engine coolant gallery and the turbocharger. The turbocharger bearing housing is water-cooled to hold bearing temperature down under load and to carry heat away after shutdown, which is what prevents the residual oil in the bearing housing from coking.

Fitting note: the O-ring must be lubricated with clean water before installation.

Frequently asked questions

What is the LR183050 water connection?
The LR183050 is the turbocharger coolant feed water connection, lower position (aftermarket, Allmakes), for the 3.0L AJ20P6 Ingenium petrol engine including PHEV. It forms the lower leg of the coolant feed between the engine coolant gallery and the turbocharger.
Why is the turbocharger water-cooled here?
The turbocharger bearing housing is water-cooled to hold bearing temperature down under load and carry heat away after shutdown, which prevents residual oil in the bearing housing from coking. The LR183050 feeds that cooling circuit, so a leak or blockage here can shorten turbo bearing life.
Is there a fitting note for the LR183050?
Yes, the O-ring must be lubricated with clean water before installation, not with oil or grease. The connection fits the 3.0L AJ20P6 petrol (including PHEV) in the New Defender, Discovery 5, Range Rover L460, Range Rover Sport L461 and Velar. Confirm your engine before ordering.
