- 6-groove pulley: check belt profile and alignment against the existing unit.
- 2 mounting holes: compare the fixing pattern and unit position.
- M6 B+ terminal: check the connection against the original unit.
- Lucas LRB00257 reference: a starting point for identifying the replacement.
Compatible Vehicles and Applications
Quote B0257 and LRB00257 with your vehicle details so the team can check the application. Compare the original part number, engine and physical unit rather than relying on a general model description.
These are selected applications, not the complete fitment list. Check the detailed vehicle compatibility table, engine code and production year, then compare the original unit before ordering.
OE Numbers and Cross-Reference Information
The following cross-reference numbers are associated with B0257. Compare them with the original unit and technical specifications; a number match alone does not establish vehicle compatibility.

When Should You Replace Your Alternator?
