There are a few methods to diagnose a radiator leak:

Pressure test: This test checks for leaks by pressurizing the cooling system.
Dye test: A UV dye can be added to the coolant, and a UV light can help locate the leak.
Visual inspection: Check for wet spots o r puddles of coolant under the car, around the radiator, and along the hoses.

If you notice any signs of leaks, its best to consult a mechanic for a more thorough inspection.
