My heat shield under my hood is falling off. you can see there it sit on the alternator and some other engine parts. would it cause excessive engine temps if I pulled it out??? Dumb Questing i know!

thanks

It will probably lower them, but your hood will get much hotter. If you drive in cold temps much, you might want to replace it. In Texas I don't see an issue with it.

If you mean the black lining on the underside of the bonnet itself, that is for noise reduction, not temperature isolation. Heat shields are only fitted around exhausts and turbo chargers.

Yes that what I mean the black liner under the bonnet. Out it comes then!

Yep, pretty much. It does block some heat, but it's prime purpose is noise.

I think im going to ditch mine. Almost seems like it could catch fire.

Not too many dumb questions here on the portal. You know that, Nate. You've been here a couple years, brother.

You probably answered someone elses question by asking!

The insulation is not required.
I ran mine for quite a while without.
When I switched to the K&N FIPK I wanted to seal the heat shield shroud to the hood. This requires the insulation.

The cowl section through the middle is open, so it is two separate pieces-

I used hood insulation retainers to attach them. Auveco part number 11130

The insulation that I used is a foil wrapped bubble sheet and is primarily a radiant heat barrier. It does deaden the sound some, but does not adhere to the metal to reduce the transfer of sound. It is available at hardware or building centers. I know HomeDepot and Lowe's carry it. It may come under different trade names. I have purchased Reflectix locally.

This might work as a good replacement for yours.

I replaced mine with a "dynamat" type material called Peel-n-Seel that I picked up for about $90 for 100 square feet of the stuff. Lined the hood, firewall, floorboard, trans tunnel, headlined the truck with it and did the seat boxes and doors with more left over. It helped keep the heat down in the truck cab and reduced noise by a ton. The hood lining really took away the tinny sound of the hood and quieted rattle and noise buy quite a bit.

Mine was gone for several years. No observed issues because of it.

Evercoat makes the same basic stick on tiles for a whole lot less $$$$. I put some on the underside of my Series bonnet about a decade ago to help with noise and it is still doing fine

Looks like a good product. I installed my stuff about 4 years ago and it still is holding tough and doing a great job. I still have about 40 sq.ft of the Peel-n-Seel left over. Dynamat is just too expensive and i was glad to find this alternative when I did, it has made a world of difference. I can now listen to the radio and carry on a conversation with people in the backseat without yelling. It also reduced heat transfer from the engine compartment by about 80%. Putting it on the underside of the roof really helped reduce noise and keep the cab much cooler in the hot Death Valley summer sun.
