A reliable power solution tailored for SUZUKI’s F5A and F5B engine series, this 12V 50A 3140075D10/1002119020 DENSO car alternator for SUZUKI F5A F5B ENGINE delivers a steady 12V DC output with a continuous 50A current, ensuring your vehicle’s electrical system—from lights to ignition—operates consistently under varying conditions.
Engineered with an internal voltage regulator, it automatically stabilizes output to prevent overcharging, safeguarding sensitive electronics like batteries and control modules. This integration simplifies installation and reduces the need for external components, making it a practical direct replacement for aging or faulty alternators.
Key specifications align with original equipment standards: a 15mm diameter shaft ensures proper fit with existing pulleys, while the 69mm single-groove pulley (3/8” type) maintains compatibility with the engine’s belt drive system. The pivot/adjustable mount, set at 165mm, allows precise tensioning of the drive belt, critical for efficient operation and longevity.
Installation is streamlined by design: the adjustable hole (M8mm) and pivot mount hole (8.5mm) align with factory mounting points, minimizing setup time. The +B output (M6) ensures secure connection to the vehicle’s electrical system, matching original wiring configurations for a hassle-free swap.
Compatible with SUZUKI models equipped with F5A and F5B engines, this alternator serves as a direct OEM replacement, ideal for maintenance, repair, or system upgrades. Its robust construction and DENSO’s reputation for durability ensure long-term reliability, reducing the risk of unexpected breakdowns.
Whether replacing a worn unit or upgrading your vehicle’s electrical performance, this alternator combines precise engineering, OEM-compatible dimensions, and consistent power output to keep your SUZUKI running smoothly.
