Keep coolant moving and engine temperatures in check with the Hitachi Astemo Engine Water Pump WUP0033 — a water pump that drops in as a direct-fit replacement for the 1989-1998 Nissan 240SX, the 1990-1994 Nissan D21, and the 1995-1996 Nissan Pickup. See the Buyer's Guide tab for the full engine-level applications. The water pump is the circulator that pushes coolant through the block, cylinder head, and radiator so heat is carried away and the engine holds its operating temperature.
Signs the original pump may need replacing include coolant weeping from the pump shaft or weep hole, a noisy or rough-turning bearing, and overheating. If a failed water pump is the cause, this replaces it. It serves as the 1990-1994 Nissan D21 water pump and the 1995-1996 Nissan Pickup water pump listed above.
