Volvo v70 D5 (mk3) - Changing a grille - Soldrax

I have bought a grille for my car on ebay, and now it's arrived, I see that the top half of it is blocked up. I understand that this means that it would have originally been on a 1.6D car and is done to enhance airflow over the vehicle.

My car is a 2.4, and I am concerned that I may face issues such as overheating - how likely is this in your opinions? Any views/tips?
