I guess one advantage to the Lund is that you can see it. I block the radiator to my F-250 and occasionally I forget about it come spring, but I do notice that the gauge begins to read a little high and remember. The only danger for the Escape is that there is no gauge to tell you things are a little warmer than they should be if it warms up a bit. As long as it runs cool enough, there's no harm done.
