Product Details

Gates 43531 is an engine water pump built for the 1999-2002 Volvo S80, including interference engine applications with timing belt drive. Gates manufactures these pumps with premium alloy materials and performs seal, bearing, and leakage testing during production to verify function before installation.

Confirm timing belt driven fitment, pulley alignment, and gasket sealing surfaces during installation. Replace worn cooling system components as needed and follow the vehicle service procedure for torque and coolant refill.
