I'm probably going to [or at least want to] improvise some homemade grille covers for this first winter with closed cell dense foam sheet, held into the grille mesh with zipties
Do I need to worry or take any kind of particular care in terms of clearances behind the factory grille mesh to the grille shutters?
I don't want to save $$ with some DIY grille covers but unintentionally cost myself $$$$ by ending up with jammed shutters, an actuator that overheats from being stuck only-partly-actuated, or some other Murphy's Law wallet-nuke
Thanks!
