Coolant Low after new Radiator fitted

[3.7 slp]

Hi All

Just a quick one to see what you all think of this
At the start of November I had the radiator replaced due to it leaking. Gave it a small top up the day after the work was done back in November
But today checked it as I was topping up the washer fuild and found that it was just under the MIN make..The car as not overheated and no warning light on Dash.

Would this be likeiy to be just the fact that it may have needed another top up as the whole system was drained and replaced with new coolant.
Just what to see what you all think, if I need to worry …and dig into the piggy bank or if that sound normal taking into account what was done.


Thanks everyone.
Steve
