Keep coolant moving and hold engine temperatures in check with the Airtex Engine Water Pump (AW9477) — a Hyundai Sonata water pump built as a direct-fit replacement for the 1999-2005 Hyundai Sonata, 2001-2006 Hyundai Santa Fe, 2001-2005 Kia Magentis, and 2001-2006 Kia Optima. See the Buyer's Guide tab for the engine-level applications. This pump is belt-driven and circulates coolant between the engine and radiator to help maintain proper operating temperature.

If a failed water pump is the cause, this Airtex unit replaces it. For a 2004 Hyundai Sonata water pump or any Kia Optima water pump on the list, this is a straightforward replacement.
