Designed to power modern electrical demands in the Renault Laguna II, this 12V 125A car alternator with 6-groove (6PK) drive pulley replaces aging or underperforming factory units in 1.8L (F4P) and 2.0L IDE (F5R) models from 2001 to 2007—ensuring stable voltage for heated seats, navigation, xenon lighting, and audio systems.
It cross-references key OEM and aftermarket numbers, including:
VALEO: SG12B055, 437361, 439394
BOSCH: 0986081270
RENAULT: 8200112065, 7711134758
DELCO Remy / WAI / MOTORHERZ: DRA4049, 23148N, ALV1662WA
Manufactured by SANYOU with 100% new copper windings, precision bearings, and an IC voltage regulator, the unit delivers consistent 125A output at engine idle (≥800 RPM), reducing battery strain during stop-and-go driving. Installation is direct—no bracket, pulley, or wiring modifications needed.
Trusted by independent garages and DIY mechanics for reliable, long-life performance in high-mileage Laguna II fleets across Europe.
