LR035630 Coolant Overflow Hose – Discovery 5 Range Rover RRS

The LR035630 coolant overflow hose is designed to properly route excess coolant between the expansion tank and cooling system on select Land Rover and Range Rover models, ensuring safe pressure regulation and system efficiency.

Over time, coolant hoses can degrade due to heat cycles, pressure, and age—leading to cracks, leaks, or coolant loss. Replacing a worn overflow hose helps maintain proper coolant flow, prevent overheating, and protect critical engine components.

This hose is designed for precise fitment and reliable performance in high-temperature engine environments, making it an essential component for maintaining your vehicle’s cooling system.

Ideal for repairing coolant leaks, preventative maintenance, and ensuring proper cooling system function on supercharged and naturally aspirated engines.
