Nissan Stagea C34 Thermostat Assembly, Series 2 RB25/20 NEO

The Nissan Stagea C34 Series 2 equipped with the RB25 and RB20 NEO engines relies on a precise cooling system to deliver both reliability and performance. At the heart of this system is the thermostat assembly, which regulates coolant flow to maintain stable operating temperatures. This genuine Nissan thermostat assembly is engineered to the factory-correct specification, featuring the proper higher temperature rating of 179.6°F (82°C) to ensure accurate function and long-term durability.

As Stagea models age, thermostats often fail or are replaced with aftermarket units that do not match Nissan’s original standards. A failing thermostat can cause delayed warm-up, overheating, or fluctuations in operating temperature that compromise performance and risk costly engine damage. By choosing the OEM Nissan thermostat assembly, owners can restore the integrity of their cooling system and preserve the efficiency and power delivery of the RB25 and RB20 NEO engines.

For enthusiasts who value authenticity and dependability, installing the proper thermostat is a straightforward but critical step in maintaining the Stagea’s factory performance. Terra Firma Automotive is proud to supply this genuine Nissan component, helping keep your C34 Series 2 running at its best. With the correct thermostat assembly, your Stagea continues to deliver the smooth, balanced performance that Nissan intended.
