Loosing coolant thinking is it the radiator?

could be a number of things. this is one of those things that youre gonna have to find out by visually checking.
could be raditor, remove the undertray and inspect.
could be water pump. inspect.
could be cracked expansion bottle. inspect.
could be be expansion bottle cap.
could be cracked/perished hoses.
could be loose jubilee clips.
could be headgasket, coolant getting into combustion chamber and burnt. could be mixing with oil.

the possibilites are endless without some clues.

Car isn’t overheating and checked oil no water ingress as oil isn’t a creamy white but will pressure test the system

Like Samisnake says it could be anywhere, but some more info is definitely required. Are you getting any puddles under the car? If so where?

I recently had a puddle at the front right of the car which pointed me towards radiator. Then another at the back in the middle which pointed towards a failed o ring on the heater matrix pipe.

On mine it was the EGR cooler, for me it did not loose any coolant unless engine was running and it was very much related to total miles driven especially at motorway speeds. If I left it for a few days and started it, there could be quite a bit of white smoke which cleared up and did not return at all as long as I used it often after that.
