auto condenser vs car rad?

[plzdontbetaken]

I have read posts where people use car radiators for watercooling a pc. I was wondering if anyone had tried using an auto condenser from a car ac unit. This would be nice because the inlet and outlet comes in standard pc tube sizes.

Ignoring that it is aluminum, how would it compare to a car radiator? Does anyone know the differences in how they are made?

I just know that the condenser goes infront of the radiator and serves a similar purpose except for the ac coolant. I don't really know anything else about how they are made or anything... which is why I hope someone can help me out =)
