Slow Coolant Leak

[Andys25]

So, I have slow coolant leak. maybe have to top up every 2 weeks or so. the car still has all the under-trays on so locating the leak is pretty impossible at the moment.

question, are there any known typical locations for leaks that i can try first. Though finding a what is most likely a pin hole in a hay stack is likely to be difficult.

any suggestions welcome.
