Bosch 0 986 017 300 Starter Motor

The Bosch 0 986 017 300 is a high‑performance starter motor designed for 12‑volt automotive applications. It delivers reliable ignition power to a wide range of vehicles, ensuring quick and smooth engine starts even under demanding conditions.

Key Technical Specifications

• Voltage: 12 V DC
• Power Output: Approximately 2 kW (2.0 kW)
• Current Draw: Up to 120 A during cranking
• Operating Temperature Range: –40 °C to +85 °C
• Dimensions: Standard metric housing compatible with most OEM mounts
• Weight: Roughly 1.5 kg (varies slightly by batch)
• Mounting Type: Flange‑mounted with integrated mounting bolts
• Connector: 4‑pole terminal block for secure electrical connection

Design Features and Construction

The starter motor incorporates Bosch’s proven high‑strength alloy steel rotor, which provides excellent torque while minimizing weight. The stator windings are insulated with a high‑temperature varnish, ensuring durability in harsh engine bay environments.

A key design element is the integrated thermal protection circuit. This feature monitors current draw and automatically limits operation if overheating is detected, safeguarding both the starter and the vehicle’s electrical system.

Compatibility Overview

The Bosch 0 986 017 300 is engineered to fit a broad spectrum of vehicles that require a 12‑volt starter with a power rating around 2 kW. Common applications include:

• Opel Omega (B and C models)
• Vauxhall/Vaughall variants
• Various BMW models that use the same mounting geometry
• Other European cars with similar 12‑volt starter specifications

Because of its standardized housing and terminal configuration, many aftermarket installers report seamless integration without the need for custom adapters.

Installation Guidelines

1. Disconnect the battery: Ensure the negative terminal is removed to prevent accidental short circuits during installation.
2. Remove the old starter: Unbolt the mounting flange and carefully detach the electrical connections. Note the orientation of the rotor for correct placement.
3. Position the new starter: Align the mounting holes with the engine block, then secure using the supplied bolts. Tighten to the manufacturer’s torque specification (typically 25–30 Nm).
4. Reconnect electrical terminals: Attach the 4‑pole connector, ensuring each pole is firmly seated and insulated.
5. Reattach battery: Reconnect the negative terminal first, then the positive. Verify all connections are tight and free of corrosion.

After installation, perform a quick test by turning the ignition key to the “start” position. The engine should crank smoothly within 1–2 seconds. If cranking is sluggish or absent, double‑check electrical contacts and battery voltage.

Maintenance Tips

• Regular Inspection: Check for signs of wear on the mounting bolts and terminal connections every 10,000 km.
• Cleanliness: Keep the starter housing free from oil, coolant, or rust. Use a mild solvent if necessary.
• Battery Health: A weak battery can cause excessive current draw, potentially damaging the starter’s thermal protection circuit.
• Professional Service: If the starter fails to engage after repeated attempts, have it inspected by a qualified technician. Internal faults such as winding insulation breakdown are not user‑repairable.
