The Bosch 0986021230 Starter is a high‑performance ignition motor designed for modern automotive applications. It delivers reliable starting power in a compact, lightweight package that fits seamlessly into the engine bay of a wide range of vehicles.

Key Technical Specifications

• Voltage: 12 V DC
• Output Power: 1.8 kW
• Operating Temperature Range: –40 °C to +120 °C
• Dimensions: Compact design for tight engine bay spaces
• Weight: Lightweight construction reduces overall vehicle mass
• Mounting Type: Standard Bosch mounting interface compatible with most OEM systems

Design and Construction

The starter motor features a robust, high‑strength housing that protects internal components from vibration, shock, and thermal stress. The stator windings are insulated with advanced materials to withstand the high temperatures generated during operation. A precision‑machined rotor ensures smooth torque delivery, while an integrated cooling system maintains optimal operating temperature even under heavy load.

Performance Characteristics

The 1.8 kW output power provides ample torque for quick engine cranking across a wide range of ambient temperatures. The motor’s high efficiency reduces electrical draw from the battery, preserving reserve capacity for other vehicle systems. Its low internal resistance minimizes voltage drop during start-up, ensuring consistent performance even in older or heavily loaded vehicles.

Compatibility and Applications

This starter is engineered to fit a variety of automotive platforms, including:

• BMW 1 Series (E87) – models from 2004‑2011
• BMW 3 Series Touring and 5 Series
• Steyr BMW variants
• Other European compact and mid‑size cars

The motor’s standardized mounting flange and electrical connections allow for straightforward replacement in existing vehicle architectures without the need for extensive modifications.

Installation Guidelines

1. Disconnect the battery: Ensure all power sources are isolated before beginning work.
2. Remove the old starter: Detach electrical connectors, unscrew mounting bolts, and carefully lift the unit out of the engine bay.
3. Position the new starter: Align the mounting flange with the engine block, secure with bolts, and reconnect electrical leads.
4. Test operation: Reconnect the battery and verify that the starter engages smoothly and delivers expected torque.

Maintenance Tips
