Hi All,
I am new at this forum. I have a Volvo V40 D2 1.6 diesel, year 2025, and after 5 months it started overheating. I have red plenty of stories on different forums, but I never came across with the result or finding out what the problem was.

On mine, it looks like the head gasket or the block is not cracked.
I changed thermostat, changed the water pump, changed EGR cooler flushed the system. EGR cooler had a tiny hole causing creating air bubles in the system.

I think there still could be something blocked or an air lock is still in the system. Does somebody know what is the best way to get air out of the system once and forever?
Also, I have red about a recall where Volvo fitted a by-pass in V40s (year 2015) from radiator to an expansion tank. Did somebody have it done? If yes, can you please share what was done on the car?

Thanks a lot,
Andy
