Genuine BMW Early M30 Type 1 Water Pump 11511266096

Genuine BMW mechanical water pump for early Type 1 M30 inline-six engines. This original used water pump features the early housing and four-bolt fan/pulley mounting flange used on various classic BMW models.

The pump is supplied in unrestored condition and shows age-related oxidation, corrosion, dirt, and previous installation marks. It has not been tested and is therefore recommended for inspection or rebuilding before installation.

Because BMW used several original and remanufactured numbers, always compare the pump housing, mounting points, pulley flange, and coolant connection with the original part.

Vehicle Compatibility

Suitable for selected early BMW models equipped with a Type 1 M30 engine, depending on production date and cooling-system configuration:

• BMW E3: 2500, 2800, 2.8 L, 3.0 L, 3.0 S, 3.0 Si, 3.2 Li and 3.3 L/Li
• BMW E9: 2.5 CS, 2800 CS, 3.0 CS, 3.0 CSi and 3.0 CSL
• BMW E12: 525, 528, 528i and 530i
• BMW E23: early 728, 730 and 733i models
• BMW E24: early 630 CS, 630 CSi and 633 CSi models

This is the early Type 1 M30 version. It should not be assumed to fit later Type 2 M30 engines without carefully comparing the water-pump housing, fan coupling, pulley mounting, and coolant connections.

Condition

Used original BMW water pump in unrestored condition. Visible oxidation and corrosion are present on the steel flange, housing, and coolant connection. The pump also shows dirt, deposits, and normal marks from previous installation and storage.

The bearing, shaft, mechanical seal, and impeller have not been tested. Due to the age of the component, professional inspection or rebuilding is recommended before installation.

Important Notes

• Used and untested
• Sold as a restoration or rebuilding component
• Pulley, fan, fan coupling, gasket, bolts, and other mounting hardware are not included
• Surface corrosion and oxidation are clearly visible
• Install only after checking the bearing, shaft play, impeller, and mechanical seal
• Always use a new water-pump gasket
• Compare the casting, housing shape, mounting holes, coolant connection, and four-bolt flange with your original pump
• If you are unsure about compatibility, please contact us with your VIN, production date, and photos of the original water pump
