Replacement of the thermostat of the Mercedes CLA 250

Model: Mercedes CLA C117, X117 - Years 2013-2019
Part: Thermostat

In this guide we will see the main instructions that will allow us to disassemble and replace the thermostat of the Mercedes CLA 250 with a 2.0 petrol engine. First of all, we open the hood of the car and start disassembling the air intake hose and then the filter box, thus being able to access the thermostat that we find underneath; then we disconnect the coolant pipe and unscrew the thermostat screws, disconnecting the electrical connector to remove it. We replace the thermostat with the new original one, finally reassembling all the other components.
