while cleaning my engine bay in my 94 runner, i kinda messed up that yellow mat thing under the hood. I was wondering how important it is to keep that and/or what have y'all done in replace of that, I think that its there to help reduce heat or noise in the engine bay maybe like spray on beliner or something. but i was just wodering that y'all have done

 

i just riped mine out and its been fine for the 2 years its been off.

 

i sprayed that cheap bedliner in a can on my hood and wish i would of left it alone. the bedliner gets hot and has a digusting smell. ha

 

Mine doesn't have it and hasn't since i got the car about 60k miles ago... so i would think its not a big deal?

 

Take it out. As far as i know its just sound deadening material.

 

its more of heat shielding than a sound barrier.

 

Ooh well that makes sense

Thanks Vitaly! Learn something new everyday.

 

ya i was thinking it was more for the heat so im just gonna leave it off and see what happens thanks for the input guys

 

For the record. Mine hasnt had it since i got it. Never had any problems with it.
But i think i know why the cats like to lay on MY yota now

 

The hood insulator serves two purposes, both of which have already been mentioned.

1. Heat repulsion/absorbtion. Its designed to keep the hood of the truck from getting overheated and ruining the paint. Most of the V6 trucks and 4Runners came with this. I think it was part of the SR5 package? The 4Cyl doesn't usually have it, since it didn't generate enough heat.

2. Sound deadening. While it doesn't make it super duper quiet, it does absorb some of the sound which quiets the truck down.
