Hood Liner

[MaxIrish]

Does the liner that is under the hood serve any practical purpose? I've never had a car with liner under the hood before - just wondering if it is purely decorative? I'm going to be adding some functional vents to my hood... things would be a bit easier if I could discard that thing... might even give a bit more room for airflow under there.

Chunk the hoodliner if you want, and the plastic engine cover.

Supposedly the huge liner has some theoretical engine fire retardation ability and is a bit of a sound suppressant.

Not at all necessary.

Thanks, KappaK. Have you chucked yours?

The plastic engine cover - yes.
The hoodliner - no.


Nephew _did_ remove both a couple of years ago now with no ill-effects.

You could sell the engine cover I know people sometimes want to paint one but not mess up the only one they have so they buy a secondary one(good way to make a penny off your "trash")

MaxIrish, if you have a GXP, I would do as John says above and pay you for it depending on the price. I'd actually like it specifically for the reason mentioned above

PM me if interested

I thought hood liners were GMs way of providing something to paint murals on?

Engine cover is for sound deadening. As much as they had to cheap these cars out to make a case for building them it wouldn't be there unless it wasn't serving a useful purpose.

First, I'll ask you the same question about your opinion as to why the engine cover is on the car. And secondly, I'll tell you that I was the only hourly material employee who worked at the plant till production began. I received and distrubited all the parts for the early buckbuilds. I asked the same question about the engine cover, wanna guess what the answer was?

Thanks for the insight g8gt09.

I'm a former GM release engineer for hood liners . . . In addition to providing some sound absorption, they protect the hood paint from damage due to engine temperatures

a good turbo blanket will really reduce the heat under the hood and help performance too.

Won't that make the turbo unit itself get hotter inside, and hence shorten its life?

Late to this thread. I tried to clean my stock hood liner and it started to peel apart. I'd really like to replace it along with at least one of the "bumpers" up near the top of the hood (in the open position) but need to find part numbers.

Anybody? I'll start searching the part number thread at lunch time... just wondered if anybody remembered seeing them posted somewhere.
