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 pump fits the VAG EA211 engine family. SEAT and Skoda models sharing this platform (e.g. Ibiza, Leon, Fabia, Octavia) may also be covered — confirm the OE number.
• Engine codes listed are representative; multiple sub-codes exist per model. Match the OE part number for positive confirmation.

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 on the engine block thoroughly before fitting the new assembly.
• Inspect the thermostat, radiator hoses and timing belt/chain while the pump is accessible; replace any worn components at the same time.
• Refill with the manufacturer-recommended coolant type (typically G13 for VAG vehicles) 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.
