Coolant Bypass Hose for the thermostat assembly on the 3.5L V8 petrol engine.

This hose connects the thermostat housing to the inlet manifold, providing the bypass path that allows coolant to continue circulating through the engine when the thermostat is closed. This ensures even engine warm-up until operating temperature is reached, at which point the thermostat opens to route coolant through the radiator.

Supplied with two size 20-32 mm hose clamps.
