After thinking about it diesel cars run cool,my car is a diesel..
I need a better plan then blocking the bottom grill.After a bit more consideration i have deduced that the air going off the bottom blocked grill would either go under the car or against then into the top grill. That can't be much of a improvement. With the top grill blocked the air stands a chance of joining in with the main air flow, that sounds like more of a improvement.
