The grille blocks on my Focus definitely help with warm up times. NOT because they are blocking the radiator, because it's not air moving past the engine block.
I hit the highway quick in the mornings. Running at 55 there's going to be a good amount of air running through the radiator (which isn't flowing any coolant since the coolant is cold) and past the engine block. Aluminum blocks don't hold heat as well as cast iron. I suspect that's why.
Makes a HUGE difference on the focus. Almost no difference on the Cherokee.
