Maintain proper coolant circulation and engine temperature control with this Genuine Nissan Bypass Water Hose, designed to suit Nissan Patrol GU Y61 models fitted with the TB45 engine. This OEM bypass hose connects between the throttle body and coolant fitting, helping circulate coolant correctly through the throttle body assembly to regulate operating temperatures and assist in preventing throttle body icing.

Over time, bypass water hoses can become brittle, swollen, cracked, or weakened due to constant heat exposure, coolant pressure, and age-related deterioration. A leaking or damaged bypass hose can result in coolant loss, poor coolant circulation, overheating, and potential engine damage if left unresolved.

Manufactured to genuine Nissan specifications, this high-quality replacement hose provides precise fitment, reliable sealing performance, and long-lasting durability under demanding Australian driving and off-road conditions.
