Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Coolant Vent Hose - connects the engine vent elbow to the radiator, within the vent (bleed) circuit of the engine cooling system.

The hose carries air and coolant displaced from the top of the engine across to the radiator, allowing trapped air to be purged from the block and cylinder heads so the cooling system bleeds itself during running and after refilling.

Applies to the 3.0L V6 supercharged petrol, 5.0L V8 AJ133 petrol and 4.4L V8 diesel engines.

Frequently asked questions

What is the LR146301LR hose used for?
The LR146301LR is a coolant hose that runs from the radiator to the engine vent elbow on petrol and V8 diesel Land Rovers. It carries coolant and helps vent air from the cooling system. This is a Genuine Land Rover hose.
Which models and engines does the LR146301LR fit?
The LR146301LR fits the Discovery 5 (3.0 V6 SC petrol), New Defender L663 (5.0 V8 petrol AJ133), Range Rover L405, and Range Rover Sport L494 (3.0 V6 SC petrol, 5.0 V8 petrol, 4.4 V8 diesel). Confirm your engine before ordering.
What are the signs this coolant hose needs replacing?
Signs include coolant leaks around the radiator or vent elbow, a dropping coolant level, or a sweet smell and steam. On these V6 and V8 engines a perished or split vent hose lets the system lose coolant, so replace it if it's weeping.
Can the LR146301LR be fitted at home?
Fitting the LR146301LR is usually a moderate job, needing the cooling system drained at the hose and then refilled and bled afterwards. Access varies by engine, so many owners on the V8 models prefer a workshop to bleed the system properly.
