Hood liners really needed?







The Best of Corvette for Corvette Enthusiasts

technologies in certain model year vehicles. That survey identified the use of underhood insulation
as a potential fire preventative feature. It was speculated that
heat from an underhood fire would melt the mounting hardware supporting the underhood
insulation, allowing it to descend onto the engine and reduce the oxygen supplied to the fire.
Another scenario was that these insulation materials might act to delay the time that the fire burns
through the upper surface of the engine compartment. Such a delay could act to extend the
survivability time of the occupant compartment."
"Given that fire resistant underhood insulating liners were identified amongst the small sample of
vehicles examined, the possibility of the liners acting to retard engine compartment fire is
plausible . However, the effectiveness of such a system can not be determined strictly from the
component tests that were performed."
As a retired firefighter of 30 years, I believe there were a few under hood automobile fires we responded on
that were saved by the liner, of course, not all.
Also as a retired firefighter, I don't use one.

However, if you look behind the insulator, your hood may not be finished very well - I know mine is not.
