Engineered by Bosch, a leader in automotive technology, this alternator combines robust construction with advanced electronic control to ensure optimal voltage regulation and longevity.

Key Technical Specifications

• Output: 150 A at 14 V DC – sufficient for full vehicle electrical demands including lighting, infotainment, climate control, and auxiliary accessories.
• Voltage Regulation: Precision electronic regulator maintains a stable output of 13.8–14.4 V across varying engine speeds.
• Operating Speed Range: 2,000–6,500 RPM – compatible with most gasoline and diesel engines.
• Weight: Approximately 3.5 kg – lightweight design reduces drivetrain load.
• Dimensions: Standard mounting footprint (140 mm × 120 mm) for easy integration into existing engine bays.
• Cooling: Air‑cooled with integrated fan housing to dissipate heat efficiently under high load conditions.

Design & Build Quality

The alternator features a stainless steel rotor and stator assembly, providing resistance against corrosion and mechanical wear. The internal winding is insulated with high‑temperature epoxy, ensuring durability even in extreme operating temperatures.

A sealed bearing system reduces maintenance needs, while the integrated freewheel pulley allows for smooth belt operation and minimal vibration.

Electronic Control & Safety Features

• Integrated Voltage Regulator: Built‑in microcontroller monitors battery voltage and adjusts output accordingly, preventing overcharging or undercharging.
• Overcurrent Protection: Internal fuse protects the alternator from short circuits and excessive load spikes.
• Temperature Sensing: Thermal cut‑off prevents overheating by reducing output when temperatures exceed safe limits.

Compatibility & Applications

The Bosch 0986049071 Alternator is engineered to fit a wide range of vehicle models, particularly those from the Ford and Volvo families. Its modular design allows it to be used in:

• Ford Focus II, Kuga I, C‑Max, Fiesta Mk5 TDCi, and Fusion TDCi
• Volvo V50, S40 Mk2, C30 D4204T/D4164T, C70 Mk2, and other models equipped with 1.6L or 2.0L diesel engines.
• Various diesel and gasoline engines ranging from 1.6 L to 2.0 L displacement, covering both petrol and turbo‑charged configurations.

Installation & Maintenance

Installation follows standard alternator mounting procedures:

1. Remove the existing unit and disconnect the battery.
2. Mount the Bosch alternator using the supplied bolts and ensure proper alignment of the pulley.
3. Reconnect the electrical harness, ensuring secure connections to the regulator and battery terminals.
4. Test the charging system with a multimeter; verify output between 13.8 V and 14.4 V at idle and higher RPMs.
