Bosch 0986020131 Starter

Overview of the Bosch 0986020131 Starter

The Bosch 0986020131 Starter, also known as a starter motor or anlasser, is a high‑performance component designed to ignite the combustion process in modern internal combustion engines. With an output of 2.1 kW at 12 V, it delivers reliable torque and rapid cranking speed for vehicles ranging from compact cars to commercial vans.

Key Technical Specifications

• Model Number: 0986020131 (also referenced as 986020131 in various markets)
• Voltage: 12 V DC
Output Power: 2.1 kW
• Operating Temperature Range: –40 °C to +85 °C (typical automotive range)
• Weight: Approximately 3.5 kg (varies slightly by configuration)
• Dimensions: 210 mm × 120 mm × 140 mm (approx.)
• Mounting Type: Standard bolt‑on with integrated mounting flange
• Connector Type: 4‑pole plug compatible with most automotive starter circuits

Design and Construction

The starter motor features a stainless steel housing that protects the internal windings from moisture, vibration, and thermal stress. Inside, a precisely wound copper coil generates the magnetic field required to spin the flywheel. The rotor is made of high‑strength alloy steel, ensuring durability under repeated start cycles.

A key design element is the integrated cooling system, which uses the engine coolant flow to dissipate heat generated during operation. This reduces wear and extends the motor’s service life even in high‑load conditions.

Performance Characteristics

• Cranking Speed: Up to 1,200 rpm at full load (typical for a 12 V starter)
• Torque Output: Approximately 35 Nm (sufficient for most passenger and light commercial vehicles)
• Start Time: 0.5–1 second from ignition switch activation under normal conditions
• Electrical Efficiency: >90% due to optimized winding geometry and high‑quality insulation

Compatibility Overview

The Bosch 0986020131 Starter is engineered for broad compatibility across a wide range of vehicle makes and models. It is commonly used in:

• Mitsubishi, Nissan, Opel, Renault, Suzuki, and Volkswagen passenger cars
• Commercial vans such as the OPEL Vivaro and Renault Master
• Light trucks like the Renault Laguna 2 Grandtour and Trafic 2 Kasten
• Various European and Asian market models, including those labeled as Motor de arranque, Démarreur Starter, or Motorino avviamento

Installation Guidelines

1. Disconnect the battery: Ensure safety by removing the negative terminal before working on the starter.
2. Remove the old starter: Unbolt the mounting flange and disconnect the electrical connector.
3. Position the new starter: Align the mounting holes with the engine block, secure with bolts, and tighten to manufacturer torque specifications.
4. Reconnect the wiring: Plug the 4‑pole connector into the starter terminal, ensuring correct polarity.
5. Test the operation: Reconnect the battery and activate the ignition switch. The motor should spin rapidly and engage the flywheel within one second.

Maintenance Tips

• Inspect the electrical connector for corrosion every 12,000 miles (or as recommended by the vehicle manufacturer).
• Check the mounting bolts for tightness annually to prevent vibration‑induced loosening.
• Avoid exposing the starter to extreme temperatures or moisture beyond its rated operating range.
