Curt Sprenger Re: Engine Compartment Hot Air Exhaust Fan

[Scott Forman]

Greg,

I can't speak for the others, but for me the installation of the fan
is about circulating air through the engine compartment after shut
down so that all the heat doesn't radiate into the bedroom. The
radiator fan moves so much air through there that these little
plastic fans will have little effect when underway IMO.
