The insulation underneath my hood is all falling down and ugly-ugly.. I don't just wanna rip it all out, cuz of the heat factor.. So what's the proper installation procedure? What kind of insulation to buy, where, etc.. What to use to install..

Any input would be appreciated, thanks.

 

what are you running? as far as engine.

if your stock...... i wouldnt worry bout the "heat factor"
but if you got da boost...... lol
or if your runnign high hp....
you might need it.......
i'd say tear that stuff down!!!

i ran my n/a hood with out... but yet again
i'm n/a stock.

 

Stock n/a at the moment - my only major plans include major exhaust overhaul and an intake.. but that won't take place till almost summer

 

dont bother putting up new stuff. your fine. just take it down your not going to run to hot to even bother the metal.

 

you can buy sheets of refelctive insulation at your local auto parts store

 

I'll look into it. How is it held in place? glue? clips? or what...

 

there are some that have a sticky side to them . so they are self-adhesive
home depo!!!
tell them your issue and the'll point you in the right direction

 

and if i just tear it down, you're sure with my stock engine, the paint wont bubble?

 

Having that insulation there is a boon, unless you are going long term without the insulation and with an expensive paint job, I wouldn't worry. (excessive heat causes paint fade). Plus, I may be wrong but i believe the insulation is also a fire suppressent, it is on some vehicles. If the engine catches fire, it's supposed to temporarily retard the fire for extra time to escape. Or maybe thats just newer cars.

 

lol................ the sun will make it hotter then the engine ever will.... unless you catch on fire ... and that you might...... pulsation dampeners rock!

 

Yeah, I had my FC for 3 months when I noticed fuel dripping onto the engine block one day.. gotta love PD's.

 

i dont hitink it would make that much of a difference unless you have a new paint job and its show q. othere than that a lot of cars don't even come w/ them . I dont see it as a prob. unless youre worried about hood paint

 

What's a pulsation dampener?

 

I pulled mine out too, it was all torn up and looked ***-ugly hanging from the hood.

No problems yet in my 87 N/A. As 87rx7girl said, having your car sitting out in the sun is going to be alot hotter than the heat from a stock 13B N/A.

 

what about after: full exhaust (header/catback) and an intake? Will that hp gain affect the temperature that much?

 

Makes me wonder if I can add insulating spray foam to the underside of the hood that closely contours the top of the engine...Anyone ever do this? ~rich

 

I'd leave that stuff there. It's supposed to act as a fire suppresent as others have mentioned. If you're sure your PD is in good shape and you don't have any fire hazards you know of (which is probably what alot of burned FC owners think before it happens) then put up the reflective stuff or just leave it off.

*edit: Doubt that **** helps much anyways, the biggest cause of fire in the FC is the PDs, and becuase of their position the fire retarding insulation probably does jack **** (hasn't seemed to save many of the burned junk FCs I've seen.)

 

You want something that absorbs heat, not reflects it back into the engine bay, especially directly above the intake manifold. If you're gonna use reflective stuff, I'd use it to seperate the exhaust manifold / header and engine from the intake manifolds and on a turbo to wrap the turbine too. (heavy guage foil - not alum tape!) ~rich

 

i have a cf hood on my N/A now,but when i had my steel one, after a lot of hard driving on a hot day. i still didnt feel like the hood is warm. so rip it out and if it looks bad to you. ill send you mine.

 

i have two, want one (or two)?

too bad you have to pick it yourself (not worth a dine on shipping :lol)

 

A pulsation damper is what sets your engine bay on fire when it starts to leak. It's on the fuel rail, and it's kind of hard to see, but it has a white-ish plastic cap, shaped something like a little mushroom, maybe an inch and a half in diameter. As you're standing in front of the car looking at the engine, it's behind and below the thermostat neck area. Hard to see it, though.

 

I took my insulation off my aluminum hood. The only things I notice are that the rain steams off of the hood (though it was coolant leaking the first time), and when I'm working over the engine, it hurts my head more when I hit the hood.

 

the design was when the engine caught fire the plastic clips would melt and cause the flame retadant insulation to drop and extinguish the fire. notice we have a section in the front towards the radiator completely uncovered i dont see how it would affect the paint reguardless i think the paint would bubble up by the radiator first

 

I've been putting more thought to this now that I've replaced my fuel rails with good solid S5 versions and noted that the engine bay temperatures could be nowhere near hot enough to damage the paint on your hood.

Think about how hot that piece gets in the blazing sun and look at all the paint in the bay as well. Mine is all intact and not flaking/bubbling, etc even enar the headers.

I'm just about ready to run out and remove that ratty *** lining out of there, especially since the fire extinquisher I carry with me will have a better chance at killing a fire IMO.

 

exactly i saw a brand new chevy pick up that had an engine fire and that crap didn't help the guy was rushed to the hospital
