Parts for your 2019 Nissan Serena-Radiator

2019 Nissan Serena Radiator — what it does and how to look after it

Yes, the 2019 Nissan Serena uses a radiator. Technical references including the Nissan Serena C27 Electronic Service Manual (Cooling System section), the Nissan FAST parts catalogue for C27 models, and major aftermarket catalogues for the MR20DD S-HYBRID and e-POWER trims all list a front-mounted aluminium radiator with electric fans for this vehicle. That makes the radiator a core cooling component on both the conventional S-HYBRID 2.0‑litre petrol and the e-POWER series-hybrid variants.

On the Serena, the radiator’s job is to shed heat from the engine coolant so the power unit stays within its ideal temperature range. The S-HYBRID’s MR20DD relies on that steady cooling for efficiency and longevity, while e-POWER models still have a petrol engine driving a generator that needs liquid cooling, with additional thermal management for the motor/inverter via dedicated circuits. The radiator assembly is a lightweight crossflow core with plastic end tanks, driven by dual electric fans and managed by the ECU.

For routine servicing, coolant quality and level are the big-ticket items. Nissan’s genuine blue long‑life coolant is typically specified, and workshops generally replace it around the 160,000 km/7‑year mark initially, then at shorter intervals thereafter
