Hey everyone,
After sorting out my brakes and a bad wire to my headlights this week, I've noticed holes in the hood insulation. I will try and take pictures but you can see a circle where it must've contacted the return resivour bottle for the radiator. There's a small, hot looking circle. There are many others from other parts of the engine..

I know this thing gets up to 220 pretty quick in the heat but I don't want the insulation to be a safety hazard.. I did some searching and couldn't find any info

It is possible it is sagging, however its fully clipped in and looks pretty tight.

Thanks!

 

Remove it if you want. Its simply for sound deadening and if you absolutely want one they make some really nice aftermarket pieces.

 

Thanks! I didn't bring that up because I had read some stuff online a out paint chipping? Not sure I believe it, or if it even matters on my car. My hood also looks a little warped already so an aftermarket one may be my next option

 

The insulation does NOT give any protection to the painted hood.

It does act as a sound deadener but that's not it's main goal.

The idea was as an engine fire blanket. This is why they are always installed with big plastic clips. Idea is if you get a fire under hood, the flames and heat will melt the plastic clips and the insulation will drop down, cover engine and smother out the fire or atleast keep it from spreading as fast.

No common under hood temp is gonna hurt your paint or wrap the metal... Keep insulation on or remove it, not going to hurt anything one way or the other.

I tend to remove all of mine as it looks cleaner without it on.

 

When I had my car painted 6 years ago we sprayed both inside and the out of the hood. The inside looks a little dirty but the top looks like glass.
Its an after market metal cowl hood that pretty thick but the bottom of my hood is not being affected.

 

Thanks so much for all the replies!

I will then probably take mine off, it is very crappy looking and may help the heat extractors work better!

 

Yeah, you won't bubble paint until you reach levels that would ruin the engine anyways. I've only seen bubbled paint once and it was on an '84 corvette that had overheated.

 

🤣🤣🤣🤣🤣🤣🤣🤣

that’s an old wives tale. That is made from fiber, and it will burn real good
