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.
