Is the thermostat on your Golf damaged? Follow these steps to remove the thermostat inside the engine bay. Lift the front bonnet of the car and identify the parts to be removed. Unscrew the screws on the thermostat housing cap (use a socket wrench with the appropriate sockets), pull off the sealing cap, and extract the coolant thermostat from its seat.

Once the part is removed, replace it with a new one and close the housing with the cap. Tighten all screws securely for safety. Ensure the previously installed part functions correctly in the engine bay of the Golf.
