I'm of the impression that all 155 have a two-speed ventilator layout, but I might be wrong.
Do your car loose coolant liquid? If not, I wouldn’t be too worried as the cooling system is under pressure and therefore doesn’t boil until at least 110 degrees. If an engine gets hot standing idling in traffic it’s a good idea to press the accelerator down a little to around 2000 RPM as this increases the coolant circulation.
