Maintain reliable coolant circulation and protect your engine from overheating with this Genuine Nissan Front Throttle Body Bypass Hose, designed to suit Nissan Patrol GU Y61 models fitted with the TB48DE 4.8L petrol engine and manual transmission. This OEM bypass hose connects to the front of the throttle body and the adjoining metal coolant pipe near the intake manifold, allowing coolant to circulate correctly through the throttle body heating circuit.

Over time, the original rubber hose is exposed to constant engine heat, pressure and coolant, causing it to become brittle, crack or deteriorate. A failed bypass hose can lead to coolant leaks, reduced cooling system performance and potentially severe engine overheating if left unrepaired. Replacing it with a Genuine Nissan component restores reliable coolant flow and helps maintain the correct operating temperature of your TB48 engine.
