My dear brothers I appreciate your comments on my radiator placement and most funny comment by @nmsheikh...
Now I think that I should explain my side...
As far as my automobile knowledge is concerned, I've been working in Indus Motor Company and have attended several training on our cars which also covered body dynamics moreover I have a humble contribution in test and trail process of Vigo Champ, Fortuner, New Corolla 368A and Prius, in which we study each and every behavior of car on several terrains in various conditions.
Moreover my friend has already placed radiator on same place and he is driving that beetle locally since 5 years without heating issues.
And the last thing,,, I know that it will heat-up on long routes due to its body shape, but I have to use it seldom in short city runs because I cant take risk of long route on a 44 years old Pakistan maintained car. And the reason for choosing this engine was just to have service availability in my native town where I have to send this car because there is no VW mechanic...
