Keep coolant circulating and engine temperatures in check with the Dayco Engine Water Pump DP751B. It installs as a direct-fit replacement for a wide range of Audi and Volkswagen applications, including the 2008-2013 Audi A3, 2009-2016 Audi A4, 2011-2017 Audi Q5, 2015-2018 Audi Q3, 2009-2017 Volkswagen CC, 2008-2014 Volkswagen GTI, and 2009-2017 Volkswagen Tiguan — see the "Vehicles it fits" section for the full list of covered years, makes, and models.
- Coolant circulation: Moves coolant through the engine block, cylinder head, and radiator to carry heat away and help hold a stable operating temperature.
- Cooling-system role: A core component of the engine's cooling loop; when the original pump fails, replacing it restores proper coolant flow.
- Signs it may need replacing: Coolant seepage or weep-hole leakage near the pump, engine overheating, or bearing whine/wobble. Diagnose the cause of an overheating condition before replacing, since other cooling parts can be involved.
- Application coverage: One pump number spanning many Audi and Volkswagen models — confirm your vehicle in the fitment list.
