After each job since it can last a few months, it means nothing was wrong then. Hoses, joints etc can deteriorate over time resulting in leakages and the reason for you to be topping up the coolant.
When problems starts, you ought to have diagnosed the source of the leak and rectified the problem. I am surprised that after so many engine changes you are still not careful with this.
Check all the clamps and hoses used. Inferior quality clamps and hoses would result in leakages at joints after some time when the hose hardens.
