LR018275 Coolant Crossover Pipe – 5.0L V8 – LR4 / Range Rover / RRS

Maintain proper coolant flow across your 5.0L V8 engine with this Coolant Crossover Pipe (Part No. LR018275). This pipe connects the water pump outlet to the engine block, ensuring efficient coolant distribution and preventing overheating—especially critical on high-temperature 5.0L V8 engines.

Over time, factory crossover pipes can become brittle, crack, or leak at the joints, leading to coolant loss and overheating. This replacement restores factory sealing, fitment, and reliability.

Designed to OEM specifications, it features the correct molded shape, mounting points, and diameter to ensure a perfect fit across multiple Land Rover 5.0L V8 platforms.

Fits:

• LR4 / Discovery 4 – 5.0L V8 (2010–2013)

• Range Rover L322 – 5.0L V8 (2010–2013)

• Range Rover Sport L320 – 5.0L V8 (2010–2013)

• Range Rover L405 – 5.0L V8 Naturally Aspirated

Install tip: Replace O-rings and inspect surrounding hoses. Consider replacing thermostat housing and plastic coolant tees during service due to common aging-related failures.
