How to replace the thermostat of the Alfa Romeo Giulietta

Model: Alfa Romeo Giulietta MK 1 - Years 2010-2020
Part: Thermostat

Today we will explain how to replace the temperature sensor on an Alfa Romeo Giulietta vehicle. The sensor, like on many vehicles, is located under the right exterior mirror. To replace the sensor, we must first remove the external rearview mirror. To remove the mirror, we will need to use a plastic parts removal tool that will be inserted into the lower right corner and the lower left corner to apply pressure outwards. Using a flat-head screwdriver, disconnect the temperature sensor from its connector to replace it, being careful not to damage the electrical cables. Insert a new sensor and reassemble the mirror and outer cover. Start the vehicle to test its operation, it may be necessary to reprogram it using the onboard computer or diagnostic computer.
