This is exactly what I have in my turbodiesel: Without grille blocks it barely keeps 78C, with both blocks it crawls up to 90C more often. Fan turns on at 97C and cools to 89C, so haven't had problem with overheating. Also, at 90 I see slightly lower fuel consumption at idle, like 0.48-0.52 vs 0.52-0.54 liters per hour.

You will notice that as you drive more efficiently, the engine will not be as hot. This is because you are wasting less energy as heat and using more to move the vehicle. You should start thinking about insulating the engine bay, this will also keep the engine from cooling off too fast, so it will be warmer when you start again after shopping, for example.

What matters is where you're going, not how fast.
