Hydrolock linked to hole in radiator?

[Kmty66]

Hi,
My car was booked in to get a small hole in the radiator fixed this morning. Yesterday I drove through a big puddle, about 30cm high. As did 100 other cars behind me and in front of me. My car stopped working. It had to be towed to a mechanic. Where upon he told me the car sucked up so much water it was hydrolock end and I need a whole new motor.
My question is- if the radiator had been fixed prior to this would the car had sucked up that much water? Was the fan sucking harder to compensate the hard working radiator? Is there a link between the two?
Thank you.
