Hood lining

[Kaasdief]

Hi clever people! What is the purpose of the hood lining? In our country "bonnet lining". Ours got damaged by a v-belt some years ago and is tatty. I am considering just removing it. Any thoughts?

 

[Chesterjrtravis]

I've heard a number reasons why the liner is there, heat insulation, noise reduction, and possible fire suppression... Can't imagine it would really matter if you took it out entirely since it sounds like yours is half gone anyway.

"Tatty" that's a good word. Haha

I took mine out years ago...no issues

After you remove it, you may be able to apply a competent heat shield product (self adhesive) to the flat areas of the underside of the hood, to make the truck somewhat quieter.

One advantage of at least peeking behind the insulation (or removing it) is that you can check to see if the panel adhesive bonding the inner and outer hoods together has failed. It has failed on several of my Toyotas. If it has, use a nasty Urethane construction adhesive to reglue it, and close the hood on a stick, using gravity to press the panels together while the glue cures.

I would think about dynamat or secondskin hoodliner could be a good alternative.

My last FJ60 did not have it and it was not a problem with a chevy 350.
My current one has but it is sagging.
Hit has two main purposes.
1. Keep the engine noise down
2. Keep the heat down on the hood itself. (That is what vents are for as well in some hoods)

Many of the vehicles I have had over the years did not have this, most that were 6-8cyl did. it does help with the noise and for sure the heat.
Without this some high heat engines (like turbo engines) will actually start to damage the paint.

Is the hood lining the same for the 60 and 62 series?

Noise reduction. It makes a big difference. Additional insulation can be added under the stock panel. Make sure it's rated for fire and heat. I used Second Skin closed cell foam and had good results.

My hood inner panels were coming apart as well. After some jb weld repairs , dynahood liner on the flat parts and replacing the OEM liner... sounds like a purring kitten when idling. Okay, maybe a feral crazy shrieking cat.

mine was removed and replaced with lineX, now my hood weighs a ton

 

[mattressking]

OEM piece is still available, right around $180 and there are quite a few in the states with more on the way from the motherland.

Sounds like I will remove, patch and refit.
