Yes, you read the title correctly. Here in Siberia, we are heading into our cold months of -30C or lower temps and one of the common practices to help protect the engines in this weather is to put a fiberglass-type blanket under the hood, over the engine. The problem is, none of them have a cutout for the Patrol intercooler (off-center). These blankets are densely woven but thin enough to fit completely over the intercooler with the hood closed without any interference.

My question is this - will the intercooler being covered like that do any kind of damage to the engine? I know the intercooler is there to cool the intake air for more efficient fuel burn, but the air is already super-cooled from the frigid temps, and keeping the engine warm is the most important factor in these conditions.

Any thoughts or suggestions? I guess I could always cut my own hole, but these things are super dense, heavy and wouldn't be easy to cut.
