Hood Heat Shield

[Smoke_Dog]

I'm in need of a new heat shield, was thinking of using Dyno Mat (Looking product at Home Depo) etc. I've seen the products on LMC but I'm not sure that I want to purchase there product! Any Ideas please address it! Thanks!!!

What do you mean by "hood heat shield"? Are you talking about insulation on the underside of the hood? What makes you think you need to replace it?

I got the LMC factory type insulator, and like it right much...

I was wanting to replace mine but I wasnt sure if the LMC kit was a big enough single piece.

It is about the same size as OEM. Only thing about running a shield,... If you blow a hose or develop a heck of an oil leak the fan picks up, it destroys it.

That's kind of where I was heading; my truck didn't come with the underhood insulation.

In fact, none of my vehicles have the underhood insulation.

Smoke Dog - I'd pull it off and not replace it if I were you.

I removed mine and was gonna flat black underneath but undecided at this point

all of my vehicles have insulation....76 gmc, 2008 silverado and my new 2011 dodge ram hemi

what is it supposed to do honestly? Just keep your hood cooler?

Yah - and cut down on the noise in the interior some.

My 84 K20 with a diesel has it and I can see the need to cut down on the noise.
Also has extra insulation pieces on the firewall.

Absolutely, additional pieces and of better material.

Weren't they also supposed to supress any fires? I know C5's were designed to where if a fire occured the clips would melt and the insulator would fall down on the motor, hopefully supressing any fire.

[Keith Seymore]

I don't recall that being a design constraint - but - maybe I just learned something.

Although - keep in mind it was not released across the board; only for the "high end" models like Silverado, which leads me to believe it was not primarily a fire retarder. Maybe a secondary design consideration, but not primarily.

I did not have the insulation shield in my 73 C20 or 76 Scottsdale and they were significantly nosier than my camper special 83 C20 Silverado with the insulation. For the low $$ involved I would have one. However, when the A/C compressor sprays oil it destroys a section of the shield.

Falling apart!!! and getting sucked into the air cleaner!

did you ever order this and replace yours?

[88Jimmy4x4]

Last weekend I sanded my hood down and flat blacked it, looked okay but with the insualtion holes and a few dings it really wasnt all that appealing to the eye so I went ahead and ordered the insualtion and clips.

Insulation came in wednesday so I installed it today after cutting it to fit.

Yes from classicparts, it has a thicker hard side that I put outward/clip side and its bigger than what you need. I just measured hood area, then cut legth/width. Then I used a coffee can as a guide to radius corners. The box said made in USA.....Arkansas I believe.

I totally understand that, luckily here in Houston thats not a problem. Honestly If truck never came with it I wouldnt have installed a new one, in fact I had hoped the painting would have made it look good enough w/o one but I didnt like seeing the holes. My semi-restoration on this 1976 is almost finished so I wanted underside of hood to look as good as engine below it.
