Are you sure it’s leaking and not burning any coolant. The N13 engine is prone to burning oil and coolant from the valve stem seals.
A way to check this is: let the car completely cool down and do a cold start. Let the car idle warm for 1 minute. Press the gas pedal until around 4-5k rpm, and check the exhaust for blue (or blueish) smoke. If that’s the case, you are burning coolant and a high probability the valve stem seals are due for replacement.
Replacing those stems won’t be cheap. While at it, I’d replace the timing chain. Those are also prone to stretching and failing starting around 100k miles.
If it’s not burning coolant and leaking as you say, it won’t be that big of a headache. Probably one of the coolant lines or the coolant reservoir. As far as i know, there are no other big issues concerning coolant.
