Maintain your Nissan Patrol’s cooling system performance with this Genuine Nissan Thermostat and Water Inlet Housing, designed specifically for GU Y61 models fitted with the TB48 petrol engine. This OEM housing assembly houses the thermostat and connects key coolant pathways between the engine and radiator, helping regulate engine temperature for efficient operation and long-term reliability.

Over time, thermostat housings can become cracked, warped, or corroded due to heat cycles, vibration, and coolant exposure. A failing housing or thermostat can cause poor temperature regulation, overheating, coolant leaks, and reduced heater performance, leading to potential engine damage if not addressed.

Manufactured to Nissan’s original equipment specifications, this direct-fit replacement thermostat water inlet housing ensures correct coolant flow, proper temperature control, and long-lasting durability without modification.
