Dumb question about hood...

[2008g8gt]

Ok, the hood liner. Do you need it on? What is it's function? Mine is weathered and looks like poop. Stained and all. Should I buy a new one or can I just leave it off?

Function is mainly noise abatement. Took mine off 6 months ago or more due to blower pulley cutting a groove in it. Can't tell any difference with it off.

It also doubles as a fire blanket in case a fire starts under the hood. It falls down and snuffs it out.

Mine looks like crap too, I'll be getting a new one though. Right after I bend down my Pedders strut bar so it doesn't hit it.

[2008g8gt]

Ok. For some reason in my mind I was worried about the heat. Thought it would cause a heat issue.

The only way to tell is to take it off. If it looks ok and you don't want to replace it, then don't. I'm going to be dressing up my next one.

[Tempest2000]

looks just like mine... who needs a fire blanket anyways LOL I'd rather have the whole thing go up in smoke than a partial fire anyways.

[DRCUSTOMPARTS]

If the fire starts while the car is in your garage and it's attached to the house you'll be screwed.

[Tempest2000]

Someone could leave the stove on and my house could catch fire that way too. Darn no fire blanket on the stove. That is what insurance is for. We have fire alarms in every room including the garage we will be alright, but thanks for your concern.

You have two choices in life... Live life to the fullest or live in fear of what might happen. I choose the former and obviously you choose the latter.

[DRCUSTOMPARTS]

Insurance won't bring you back to life, but it's your life so do what you want. I'm just trying to be helpful but you seem to know it all.

Fire blanket, really? That has not been my experience of hood insulation.

From the car fires I have seen or experienced the insulation on the hood usually enhances the fire or is what gets torched in the first place. I know on my truck when it backfired through the carb that was the first thing to go up in flames after the element in my wire mesh aircleaner.

Removing it should not cause any problems other than more engine noise and that's a good thing right?

I know on old vettes (think C1 and C2) if they pop their hood at a show or something they will put a towl over their chrome aircleaner because the heat caused by the reflection will cause their paint to bubble. I don't think you will have this issue with a metal hood and most of the underside plastic, flat black or grey.

[DRCUSTOMPARTS]

Notice that the insulation is held on by plastic screws. If a fire starts the plastic screws melt, the insulation drops and helps to snuff out the fire.

Hood liners help insulate the hood so it doesn't warp or cause paint damage from engine heat. They also insulate against road and engine noise. Back in the day they were made from asbestos to help act as a fire blanket and I'm sure they still are today eventhough they moved away from asbestos.

In my experience though they don't do a very good job of helping prevent fires and most of the time they burn with the fire as it's only fire resitant, not fire proof. They also absorb a lot of chemicals which probably doesn't help their case.

I tend to think of them a lot like header wrap. It insulates and keeps underhood temps down, but they also hold in moisture causing headers to rust and they absorb chemicals which turn them into a fire hazard.

[Tempest2000]

My dads grand prix caught fire and the blanket didn't do any good other than add to the mess. Total loss. The best it will do is buy you a little time to get out if you are in the car.

[wreckwriter]

I'll stick with my original statement- noise abatement only.

Pretty much....I thought about getting a nice one, but they just get too cruddy too fast. I have 12K on my car and it's already got stains everywhere and makes me not want to open my hood. I'm sure there are some nice stainless ones that are insulated on the backside but probably $$$.

Mine was weathered like the OP's after driving the car all winter. Just took it off with no problems, at least I can wipe down the underside of the hood which looks better then the stained liner.

Do you have pics of the underside of the hood without the liner? I have the same stain problem and was considering repainting or removing the liner.

[DRCUSTOMPARTS]

Spray it with some flat black paint, that should cover the stains.

[ulakovic22]

I haven't tried removing or re-painting mine yet, but a can of paint sounds easy enough. Not sure if it would require high temp paint or if std would work.

I looked at the ACC one and it's $400, not sure if I want to go hog wild or not. I could definitely hide purge lines to the snorkel behind it though :)

I dont have a pic handy but it just looks like dimpled metal under the liner... its fully painted so nothing to worry about.

[J Wikoff]

They do clean up fairly well if you take it off and hose it down.

I had this exact thing happen with a field car I had. Cracked fuel line at the carb pouring gas all over the engine compartment, engine up in flames. Then the pins melted and the blanked dropped....

[ulakovic22]

Was the blanket able to snuff out the fire or at least give you time to get something else to put it out?

[2008g8gt]

I'd rather the whole car blow up :-)

Then your garage will blow up with it.

[2008g8gt]

I wish I could park in the garage. I park far from th house or anything for tha matter.

You need to build a bigger garage then. I have a 2 car garage and wish it was twice the size. I have the room but not the money though.

I have just removed my hood liner as it looks like the OP's. Here are some pictures of the naked hood.

Those that have removed theirs...have you noticed any ill effects to the paint? My assumption is that if the rubber hood vent 'liners' have not melted then it seems unlikely that it would damage the paint. I'd like to be proven wrong sooner rather than later though, if it's going to happen!

[Shredmo]

Does the Rotofab seal correctly with the liner removed?

Edit: just realized this is a very old thread, lol!

[I12XLR8]

Sorry, in looking back at the pictures I realized that I didn't leave enough of the engine in the pics...I have the VaraRam intake so it's not an issue.

I'm sure someone else can answer that though.

With RF you probably need to keep it.

[Shredmo]

Thanks Wreck. Since the OP has a roto, thought that might be important.

Question about what to do with deteriorating (falling down)
insulation in back of engine where cowl is located.Will it
hurt anything to just remove it?

I've cut the floppy part of mine off; no ill effects.

Not true. Ask me how I know.

Anyway, thanks for bumping a 5 year old post.

[arasbury]

Please explain fully and in detail.

[BuildItYourSelf]

Haha. I would think the binder would add fuel but the fiber would cause it to block air. Either way if you has to yourself. "I hope the hood liner puts out my engine bay fire" your fucked anyway. Just stop and turn off the fuel pump and let her burn.
If you super worried buy a fire suppression system.

[gr8lover]

the hood liner is for sound..... thats it... fire suppression only in someones fantasy land...... if it was for fire.. there would be warnings all over it....

dont ask ray..... he doesnt want to go thru his fire all again.... not a good thing to experience.. icant even imagine..

you will hear so many experts that heard 30 yo stories about how they are fire suppresion but its just a fantasy..... imagine burning fuel/oil stopped by a little blanket.... hmm.. not going to happen....

remove it completely and just spray paint the underside and looks awesome!!!

[BuildItYourSelf]

Fire blanks work very well actually. I have used them.
It's basically a fiberglass blanket with some type of fire retardation crap one them. They just cut off the air supply and insulate the heat so you can hold them on something long enough to get it in place.
I remember seeing a video once about firet companies experimenting with them for car fires and suck.

But you are correct the hood liner is for noise and insulation from heat to protect the paints life span.
