Maintain reliable engine cooling and prevent overheating with this Genuine Nissan Upper Top Radiator Hose, designed for Nissan Patrol GU Y61 models fitted with the TD42Ti turbo diesel engine. This OEM “skinny” top radiator hose connects the radiator to the engine, ensuring proper coolant flow through the cooling system under all driving conditions.

Over time, radiator hoses can become brittle, cracked, swollen, or softened due to heat cycling, coolant exposure, and engine bay pressures. A damaged or worn hose can lead to coolant leaks, rising engine temperature, poor heater performance, and potential engine overheating — especially under load or in hot environments.

Manufactured to Nissan factory specifications, this genuine upper radiator hose ensures correct fitment, secure sealing, and long-lasting durability. It is an ideal replacement part during cooling system servicing, radiator replacement, or preventative maintenance on your TD42Ti-powered Patrol.
