The coolant temperature sensor in a 2010 Ford Fusion plays a critical role in monitoring engine temperature and ensuring optimal performance. For car owners or mechanics looking to locate this sensor, understanding its position is essential for maintenance and repairs.

Location of the Coolant Temperature Sensor

The coolant temperature sensor is located on the driver's side of the engine, specifically near the throttle body and air intake system. Here’s how to find it:

  • Look underneath the throttle body on the driver's side.
  • The sensor will be positioned close to the lower corner of the radiator.
  • You may need to remove some components or panels to gain better access.

Steps for Accessing the Sensor
