I took the hood insulator off of my car because I needed just a tad more clearance for my new coolant expansion tank. (It sticks up a little further than the OEM one and it was rubbing.) Anyway, I know the insulator is supposed to help the engine warm up faster when it's cold out... which I don't give a shit about because I only drive the car when it's nice. I also read somewhere that if a fire ever started under the hood, the push-pins holding it up would melt, the insulator would drop down and "blanket" the motor to try and smother a fire out.... is that true and has anybody else ever heard of that? Is there really any other benefits to leaving the insulator on?
