I have used a FIA Winter Grille Block for the upper portion of my Grille opening--see in the photo section for a view. I have taken out the lower grille block and driven over 1000 miles in the last few weeks with no problems at all. Of course, it has only reached 80 degrees F once during this time frame.

How easy is it to remove your grille blocks? What holds them in place? Do you have a Scan Guage to monitor the vital engine components?
