The only thing that a hidden winch would do is reduce airflow through the intercooler. That has nothing to do with the heating/cooling of the engine and it could not cause engine damage. The ONLY thing that the intercooler does is cool the in coming air from the air intake going into the turbo. At the worst, blocking airflow would raise intake temperatures to the ambient air temperature. By doing this you would loose maybe 5 to 10 horsepower. Maybe.
I just went and looked at my truck, and man! there is a lot of space in between the bumper and the engine.
