The Nissan 21010-AA527 is a Genuine Nissan OEM Water Pump, designed to be a direct replacement for various Nissan models. It ensures proper engine cooling by circulating coolant throughout the system, preventing overheating and maintaining optimal engine performance. This water pump is compatible with engines such as the RB25DET, RB25DET Neo, and RB26DETT. It is specifically listed for vehicles including the Nissan Cedric/Gloria Y34 (2003 250S 4WD Automatic), Nissan C34/C35 Laurel, C34 Stagea (including 260RS RB26DETT), R33 Skyline (GTS/T and GTR), R34 Skyline (GT/T Neo and GTR), and Y33 Cedric/Gloria (RB25DET Neo). Included with this water pump are a replacement water pump housing gasket and a set of fan blade studs, providing essential components for a complete installation. While manufactured to OEM specifications, some sources note slight variations in the inner housing for RB25DET Neo applications compared to identical OE Nissan parts, though it remains interchangeable.
