LR073684 Genuine Valve Piston Oil Cooling
The genuine Land Rover piston oil cooling valve for Ingenium engines carries part number LR073684, also cross-referenced as AJ813393 on Jaguar applications. It is fitted across Ingenium engine variants, including the AJ20D4 diesel and AJ20P6 petrol, covering the Defender L663 from 2019, Discovery Sport L550, Discovery 5 L462, Range Rover Sport L494, Range Rover Velar L560 and Range Rover L405. Always confirm your VIN and engine code before ordering, as fitment varies by build date.
Regulating oil flow to the piston cooling galleries in the cylinder block, the valve is a precision component on a high-value engine. When it sticks or seizes, the cooling circuit is disrupted, piston temperatures rise under load, and wear accelerates to the crowns, rings and bore. Low-cost to replace, expensive to ignore.
