This answer was rated:

I have a 2009 Smart For 2 Passion that is setting a P0116 and P0117 code. The radiator was damaged and it did get warm, The code did not set until after the radiator was repaired. It is also getting bubbles and pressure in the expansion tank when running and it was suggested that it may have blown a head gasket.

The first thing that you want to do is check the cooling system for any exhaust gases. There is a tester for that, that you can gt from Autozone for about $20. It comes with instructions, but there is a blue fluid that is used in it, if the fluid turns yellow, that is exhaust gases.

If there are any exhaust gases in the cooling system, that will cause more pressure than desired and will allow the engine to burn coolant and/or heat the coolant up too high. Most times not filling the crankcase with coolant either.

If there are, then there would be an internal engine problem, like a head gasket or head.

Of course, you will want to make sure that the system is full, the coolant is circulating, and the cooling fan(s) are working as well as the pressure cap holding pressure. Thanks
