The coolant temperature sensor is situated on the engine block, typically near the thermostat housing. Here’s how to find it:

  1. Open the Hood: Ensure the engine is cool to avoid burns.
  2. Locate the Engine: The sensor should be near the top of the engine, often on the passenger side.
  3. Visual Check: Look for a small, cylindrical component with a wiring connector.

Replacement Steps

If you need to replace the sensor:

  • Disconnect Battery: Always disconnect the battery first for safety.
  • Remove the Sensor: Carefully unplug the wiring connector and unscrew the sensor from its housing.
  • Install New Sensor: Screw in the new sensor and reconnect the wiring.
  • Reconnect Battery: Finally, reconnect the battery and start your vehicle.

Troubleshooting Tips

If you’re still facing issues with the temperature gauge:

  • Check for Fault Codes: Use an OBD-II scanner.
  • Inspect Wiring: Look for any damaged wires that might affect sensor signals.

Using this guide, you should be able to locate and troubleshoot the coolant temp sensor effectively. If anyone has tips or additional info, feel free to share!
