In last month I had to top up 3 times.
I don’t see any leaks. I also have replaced the radiator cap but still the same.
That’s any one of you had similar problem.

Hi,
Reportedly, most frequent, least noticeable and easiest/cheapest to fix leak source is this thing:
coolant temperature sensor. More specifically, it's the sealing o-ring (green)
to be replaced, not even the sensor itself.
