This GMB Water Pump replaces the original equipment unit on Mazda BT-50 3.0L Turbo Diesel models built from 2021 to 2023. Weep hole seepage is the classic early warning of a failing pump; replace before the bearing fails. The impeller is precision balanced and the shaft runs on a double-row sealed bearing rated well beyond the belt service life. The Cast Aluminium housing is pressure tested and supplied with a new gasket or O-ring. Always refill with the correct coolant type and bleed the system fully to avoid an air lock. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. Packaging and labelling include the part number and application data for easy stock control. Sold new with 2 Years / 40,000 km warranty cover and full technical support.
