Vehicle Fitment

Fitment Notes

• Always verify the OE part number stamped on your existing water pump before ordering. Fitment data is provided as a guide and may not cover every sub-variant.
• The Ford Ranger and Mazda BT-50 / B2500 share the same Mazda WL/WLT/WEAT diesel engine platform; OE numbers from both brands are listed above for easy cross-referencing.

Installation / Use / Maintenance Tips

• Drain the cooling system completely before removing the old water pump to minimise coolant loss and contamination.
• Clean all gasket mating surfaces thoroughly and use the supplied gaskets and seals — do not reuse old gaskets.
• Inspect the thermostat, radiator hoses and drive belt while the pump is accessible; replace any worn components at the same time.
• Refill with the manufacturer-recommended coolant type and concentration, and bleed all air from the system before starting the engine.
• Run the engine to operating temperature and check for leaks around the pump housing, hose connections and bleed points.
