Could be leaking from -
Radiator Hose
Heater pipe manifold seals [in the front of the engine]
Heater Hose
Heater Tap
Heater Core
Radiator
Radiator Cap [as previously mentioned]
LIM gaskets
Head gasket [unlikely, but not impossible]

That's a starting point to look at
The best thing is to lay a drop sheet on the ground and park the car over it,
That will give you an rough indication the where its leaking from, then go searching,
If you don't have any anti-freeze/anit-boil in it,
put some in there to colour the water, that way when it does leak, it will leave a trail of water, and also see it on the drop sheet.

It's quite possible that it's the tell tail from the water pump...…..it could also be leaking from somewhere else such as a welch plug as was suggested above
Trying to get lucky and guess the issue is just a waste of time and your money
If you get the cooling system pressure tested, it'll identify exactly where the leak is, and then you can fix it yourself or have it fixed without chucking multiple random parts and dollars at it in the hope of getting lucky
