Maintain reliable coolant circulation and correct engine operating temperature with this Genuine Nissan Rear Throttle Body Bypass Hose, designed to suit Nissan Patrol GU Y61 models fitted with the TB48 4.8L petrol engine and manual transmission. This OEM coolant bypass hose connects to the rear of the throttle body (closest to the firewall) and forms an essential part of the engine's cooling system, allowing coolant to circulate correctly through the throttle body.

Over time, throttle body bypass hoses can become brittle, crack, harden, or deteriorate due to constant exposure to engine heat, coolant, pressure, and repeated heat cycles. A damaged hose can result in coolant leaks, reduced cooling system efficiency, overheating, and potential engine damage if coolant loss is left unchecked.

Manufactured to Genuine Nissan specifications, this high-quality bypass hose provides precise fitment, excellent sealing performance, and long-lasting durability. It is the ideal replacement during cooling system servicing, throttle body repairs, or preventative maintenance on your Nissan Patrol TB48.
