Is there a mechanical reason I > need to switch to a higher temperature thermostat for the winter? Why should a coolant temperature of 82C be OK for the engine in summer but not in winter? After warm up, an 82C thermostat should maintain that temperature regardless of the outside ambient temperature unless it is faulty. It is easily checked. Remove the thermostat and verify it is closed when cold. Heat it in a saucepan of water on your stove and with a cooking thermometer check that it opens at its rated temperature.
