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.
• This is the 3-hole thermostat cover variant. Some N47D20 applications use a different thermostat cover configuration — count the holes on your existing pump to confirm.

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 — do not reuse old gaskets or seals.
• Inspect the thermostat, radiator hoses and drive belt while the pump is accessible; replace any worn components at the same time.
• Refill with BMW-approved coolant 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.

Common Questions

Will this water pump fit my vehicle?

Check the fitment table above and confirm the OE reference number matches the one on your current water pump. If your vehicle and engine code appear in the table and the OE number matches, this pump is a direct fit. Also confirm the 3-hole thermostat cover matches your existing pump.

What do the OEM reference numbers mean?

OEM (Original Equipment Manufacturer) reference numbers are the part numbers assigned by the vehicle manufacturer. They let you cross-reference this aftermarket part against the original to confirm compatibility.

Is Partquip the same as MAP Pro?

No. Partquip is an independent aftermarket brand. MAP Pro is the house brand of Modern Auto Parts. Both are available in our store, but they are separate brands with their own product lines.
