Operating temperature is not reached, thermostat and coolant flange
On the vehicle mentioned above, it can happen that the operating temperature is not reached. Sometimes the temperature display in the instrument cluster shows a "cold engine".
The cause can often be found in the area of the thermostat, which does not close properly.
The thermostat is located on the engine block, behind the alternator.
After removing the coolant flange, the thermostat can then also be removed together with the sealing ring.
Before installing the new thermostat, the coolant flange should be inspected.
Part of the plastic guide (installation aid) often breaks off here.
It is then advisable to replace the flange.
