Do not confuse early and late E38 V12 pumps
The fact that another water pump fits an E38 750iL does not prove that it replaces 11510393337. Production date matters, especially around the late V12 configuration.
Use the VIN and the original component number before purchasing an expensive rare pump.
Why the failed pump should be retained
Once an original component becomes discontinued, the housing itself can be valuable. A specialist rebuilder may be able to inspect the shaft, bearings, sealing surfaces and impeller and determine whether the original can be restored.
Used original pump risks
A used pump solves the fitment problem but remains a decades-old wear component. Treat an unknown used unit as a candidate for inspection or rebuilding rather than assuming that it is ready for another full service life.
- Check shaft play.
- Inspect the housing for corrosion.
- Inspect sealing surfaces.
- Check for previous coolant deposits.
- Confirm BMW identification.
- Ask donor production date.
