Keep coolant circulating and engine temperatures in check with the Dayco Engine Water Pump DP1903. It installs as a direct-fit replacement for the listed applications, including the 2015-2025 Volvo S60, 2017-2025 S90, 2015-2025 V60, 2015-2025 XC60 and 2016-2025 XC90, all with the L4-2.0L engine — see the Buyer's Guide tab for the full list.
The water pump drives an internal impeller that moves coolant through the engine and radiator to carry away heat. A worn pump can cause a coolant leak at the weep hole, bearing noise, or engine overheating; if a failed water pump is the cause of your cooling trouble, this replaces it. Diagnose the underlying cause before replacing.
