Product Number: 23837N
The WAI 23837N is a brand-new 12V 120A alternator. It is built to replace VALEO original-equipment units, with direct cross-references to VALEO SG12B052, SG12B081, SG12B098, and SG12B109. Designed as an IR/IF (internal regulator, internal fan) unit, it delivers the same output characteristics as the VALEO factory-fit alternator it replaces, making it a straightforward, like-for-like swap for the applications listed below.
Constructed to meet original-equipment specifications, the 23837N features clockwise rotation and an S7 pulley, matching the geometry and drive configuration of the VALEO alternator it supersedes. The IR/IF design means the voltage regulator and cooling fan are both housed internally, keeping the installation clean and eliminating the need for external regulation components. WAI carry a Lester reference of 23837 for catalogue cross-referencing purposes.
This alternator fits Renault vehicles across 8 confirmed applications, including the Megane, Megane Classic, Megane Grand Scenic, and Megane Scenic spanning model years 2002 to 2010. Fitment should always be verified against your vehicle's make, model, engine variant, and build date before ordering.
