The insulation on my 94 4Runner is in pretty poor shape and is starting to sag. I noticed when I raised the hood yesterday the throttle body is starting to pull and fray the insulation. Several of the clips are broken and the insulation has a black burnt look to it. Can this catch fire?

I suspect that if I remove it I will develop paint issues on the hood? Cracking, fading or clear coat peal?

Anybody remove their insulation? Have you had any issues?

Any tips on the best way to mount it back up there?

 

you might develop paint issues it just depends on how hot the hood gets. i would remount it if i could but don't worry too much about it.

 

You'll hear more engine noise without it and the hood will get WAY hotter as stated.

 

My insulation was doing the same thing on my 92 Four Runner. Clips were dry rotted and missing. The insulation wasnt hanging too low but it looked nasty.
I went ahead and tore mine off. All I did was pop the remaining clips and took everything off. Yeah your gonna hear the motor more but thats all I heard thats for is to keep the noise down from the engine bay.
I have owned five cars and none of them had the hood insulation on them. And I use to live in El Paso Texas and now I live in Las Vegas Nevada and have had no problems with the paint getting bad on the hood and both of these places get pretty hot in the summer. Shoot! My 69 Stang has no hood insulation and runs pretty hot in the summer and I have had no problems with that car either.
I also read that it could help with the 3VZE motor in the cooling department. It might keep the engine compartment a little cooler with the hood insulation which is a plus with the 3VZE.
Just my 2 cents.

 

without it.... your paint WILL oxidize and peel ...I know cuz I did the same thing to my 93, and the only paint that has peeled is on the hood.

 

Mine never had any sort of insulation on it from the day I got the truck

but, during my still in progress motor rebuild, I lined the bottom of it with rubberized undercoating

won't blanket any fires like the OEMs will, but still look's decent, and will cut down on the hood's "floppyness" I'm hoping

 

I never had insulation when I bought my truck. But I do have paint peeling which I thought was from a combination of rocks or something hitting it as the peels are in the very front and from shotty paint as there is primer exposed in the door jams too.
My truck is loud as well, I though I had problems at first, but thats just the way she is and I dont mind anymore.

 

You might be able to find a decent hood mat at a junk yard to replace it with if it means that much to you.

 

I'd just get myself an order of dynamat hoodliner. I wont have to worry about the issue of the heat on my paint or the sound. The sound is my main concern, I'm trying to get all the bang-for-the-buck I can out of my stereo, and the less I hear the outside world the better. I love dynamat products, but I'll readily admit that I've never used their headliner product myself. Thats just what I would do if I had a hoodliner missing.

Oh, and feel free to take a trip to autozone or whatever's near you and have a look at the clips and screws department. That may just be the kind of thing they have on their racks collecting dust. Thats where I go if I snap an interior upholstery clip or somesuch.

 

For the replacement clips you can also try ACE hardware, they have a good selection of the clips near me. Also try upholstery suppliers. Again I have had good success in finding not only these clips but many of the interior clips as well as vinyl and plastic paint that is very close to my rigs interior.

 

For the clips i would go to NAPA they have a million different clips

 

I would try and find a way to remount it or get a new sheet and remount that.

That will help greatly in a fire as it will eventually fall off and blanket a fire if that were to ever happen.

Hood insulation? Should my '86 runner have hood insulation?

 

I'm not sure what year they started putting it on them.
My '85 doesn't have a hint of it.

^^^Neither does my 88 i dont think they came with them

 

My 91 truck went without it for the first 17 years of it's life; I added it, but it doesn't seem any quieter; the hood has the shiniest paint on the truck.

 

Neither the previous '94 nor my current '94 came with hood insulation. I know a guy who has a '91, 92, or 93(I forget which) 3.0/4x4 that never had any. The paint on my hood is no worse than the rest of the truck. I also have a turbo Mustang model known for slow cooking the underhood wiring. It has cooked wiring and no hood insulation, but again, the hood paint is no worse than the rest.

 

It wont catch fire but if you remove it your paint will suffer and eventually peel

 

Awesome. Thanks everybody. I will try and reattach the broken or pulled through clips.

 

Clips and parts like that are actually not too spendy from the stealership. They can pull up a picture and get you part numbers.
