Technical Specifications

Installation Guide

1. Disconnect the battery: Ensure safety by removing the negative terminal before working on electrical components.
2. Locate the existing sensor: Typically mounted near the engine block or coolant reservoir, connected to the cooling system via a flexible hose.
3. Remove the old sensor: Unscrew the mounting bolt and gently detach the connector. Note the orientation for correct reinstallation.
4. Install the Bosch sensor: Align the 3‑pin plug with the socket, secure the mounting bolt, and tighten to manufacturer specifications (usually 30 Nm).
5. Reconnect the battery: Restore power and verify that the engine control unit (ECU) registers a valid temperature signal.
6. Test operation: Run the engine to operating temperature and confirm that the sensor’s output matches expected values via diagnostic tools.

Maintenance Tips

• Inspect the connector for corrosion or loose contacts periodically, especially in high‑humidity environments.
• Avoid exposing the sensor to extreme mechanical shock; handle with care during removal and installation.
• If the ECU reports a fault code related to coolant temperature, consider cleaning the sensor’s contact points before replacement.
