Maintain correct engine operating temperature and cooling system performance with this Genuine Nissan 82°C Thermostat, designed to suit all Nissan Patrol GQ and GU models fitted with TD42, TD42T, and TD42Ti diesel engines. This OEM thermostat is a critical component of the cooling system, regulating coolant flow to ensure the engine reaches and maintains its optimal operating temperature.

Over time, thermostats can become stuck open or closed due to age, corrosion, and constant heat cycling. A faulty thermostat can cause overheating, poor engine efficiency, excessive fuel consumption, reduced heater performance, and premature engine wear if left unattended.

Manufactured to genuine Nissan specifications, this precision-engineered 82-degree thermostat provides accurate temperature control, dependable operation, and long-lasting durability for both daily driving and demanding Australian conditions. This thermostat opens at 82°C and includes the thermostat only; gasket sold separately.
