Overview
The Range Rover L405 (2002–2009), Range Rover Sport L494 (2005–2009), and Land Rover Discovery 3 LR3 are built on legendary powertrains—but they demand precision cooling. The 4.4L V8 petrol engine generates significant thermal load, especially during towing, sustained highway driving, or off-road work. Oil temperature control isn't optional; it's essential to engine longevity and performance consistency.
This OEM-equivalent oil cooler restores factory cooling capacity through a precision aluminum core design and optimized flow architecture. Engineered to meet Partsmost standards, it maintains oil viscosity across driving conditions, preventing sludge buildup and protecting critical bearing surfaces. Whether you're touring the Scottish Highlands or crossing challenging terrain, controlled oil temperatures mean controlled power delivery.
Direct bolt-on fitment requires no modifications. Installation is straightforward for owners with basic mechanical competence, and the 1-year warranty covers defects in manufacturing. This is genuine cooling system restoration—not a compromise.

Installation Notes
Difficulty Level: Intermediate | Time: 2–3 Hours
-
Disconnect battery negative terminal and allow engine to cool completely (minimum 1 hour).
-

-
Disconnect hose clamps and remove fasteners holding cooler assembly to block.
-
Carefully withdraw old cooler and inspect mounting surface for debris or damage.
-
Clean mounting surface thoroughly with lint-free cloth; allow to air-dry.
-
Install new gasket around mounting face; ensure even seating.
-
Position new cooler with inlet/outlet ports aligned to original hose routes.
-
Secure mounting bolts in criss-cross pattern; torque to 18–22 Nm (do not over-tighten).
-
Reconnect inlet and outlet hoses; tighten clamps firmly but not excessively.
-
Refill coolant and oil to factory specifications; bleed air from cooling circuit.
-
Reconnect battery and run engine at idle for 5 minutes; check for leaks.
