Well, there is your problem.

Drain the system, reverse flush to get all the radweld out. Fit new radiator, refill with coolant, bleed and run to find the leak. Fix leak properly, refill, re bleed, run and check, continue till sorted, and pray the headgasket has survived.

Well that depends entirely on where the leak is.

Drain the system by removing the bottom hose.

Remove the radiator, and put your hose up the bottom hose to get the water running backwards through the system.

Replace the radiator with a new one, fill the system with water, and run the engine to identify the leak.

Repair what leaks.
