Firewall Insulation Installation


Recommended Posts

readily available 3M contact adhesive is adequate.  brushable or spray.  remember that there are tabs at the bottom of the firewall that help to secure it in place in addition to the brake lines up top. 


i have mixed feelings on the insulation as it entraps moisture if the heater plenum drain openings are not properly cleaned.  but, i have not driven a car without so i don't know how much more engine noise would transmit.  additionally, the last time i checked that insulation piece was pricey.  i have seen HVAC insulation type aluminum backed material used as an alternative.
