Hood insulation

Hi Folks,


I am not sure if this has been discussed before but as we know the new non-hybrid RAV4s do not have the hood insulation. Any ideas how to add this using a third party insulation or something. Perhaps, buy the insulation from Toyota itself once the hybrid is released - looks like the hood sizes are pretty similar.



Thanks!

Yes, it's been discussed before, no one lists 2019 Rav4 OEM parts yet, some dealers don't even list 2018 yet, but other late model Toyota hood "insulators" cost around $250 and up, Dynamat Extreme can be had for about $150 less.

Ordered a 2019 RAV4 Hybrid AWD (XSE HV Premium) in Zircon Silver / Attitude Black.
For now my Black-and-Blue 2018 C-HR Hybrid Bi-tone Premium will do.

I looked at the hood of my adventure. There seems to be a lot of openings for ventilation and air circulation. Are you sure the dynamat insulation is not going to overheat the engine?

There are no vents on the hood, just reinforcing for the aluminum hood and the washer plumbing. I'm only insulating the same area as the HV OEM insulator covers but I'm using Second Skin Damplifier Pro which is thicker than Dynamat and US made, and maybe a DEI Boom Mat liner that I'll attach using OEM fasteners in the factory attachment holes.

Got the Second Skin Damplifier Pro installed, now just need some dry, warmer weather to finish up with the hoodliner, decided to go with Dynamat Hoodliner instead of the DEI. I'm not using OEM fasteners, I decided to apply the liner in 3 sections that stick right to the Second Skin leaving the washer plumbing in between the sections for future access, then cover the edges and joints between the sections over the plumbing with DEI Cool tape.

I used Dynamat 11905 Hoodliner 32" x 54" x 3/4" Thick Self-Adhesive Sound Deadener (amazon.com) in my 99 RAV4 with excellent results. I used 3" aluminum insulation tape to tape up all the edges and a heat resistant spray adhesive to hold it in place. It keeps the hood much cooler and soaks up the sound.


It may be that my sole purpose in life is simply to serve as a warning to others.

So did it work? Did you notice a reduction in engine sound?

Yes, there's a noticeable decrease in engine noise, specially the mechanical sounds during warm up, I expect the hoodliner will reduce engine noise substantially more in comparison tho.
