It could, depending on how completely you block your grille. Recommend you have a good way of monitoring your temperature so you can keep track. A ScanGauge will do it, and a whole lot of other stuff.
When I blocked the grille on my Jimmy, it started running hot until I cut a hole for cooling air. I had to enlarge the hole once, and then that did the trick.
