Product Number: 13998N
The WAI 13998N is a brand-new 12V 140A alternator. It is built to replace Bosch original-equipment units — including Bosch references 0 124 525 014, 0 124 525 029, 0 124 525 529 and 1 986 A00 895 — across 101 Volvo applications. It is a direct-fit replacement for Volvo models such as the S40 I, S60 I and related variants, making it a reliable choice whenever the original Bosch unit needs renewal.
The 13998N is designed to Bosch IR/IF specification — internally regulated and internally fan-cooled — which means it requires no external voltage regulator and runs cleanly within the original electrical architecture. The 140A output matches OE charging capacity, and the counter-clockwise (CCW) rotation and SC6 single-claw pulley ensure correct belt engagement without modification. The Lester reference for this unit is 13998, which is widely used across trade catalogues for cross-referencing purposes.
As a brand-new unit rather than a remanufactured exchange, the 13998N carries no core charge and arrives ready to fit without the need to return a worn original.
