Under hood Insulation

[metro1]

I assume my 59 Galaxie had insulation under the hood at one time. Does it need to be replaced? If so with what? I'm not making a "show car" just a driver so I really don't care about the appearance.

Our '60 Fairlane doesn't show signs of any insulation. Was some in the trunk lid but was mostly gone. removed remaining and replaced it with undercoat to appear correct. problem is the undercoat is so heavy lid won't stay up!!

Thanks for your answer. I was looking at some discussions online and it seems to be some for and some think it isn't necessary. I think I'll just repaint it and move on.

My '55 originally had insulation under the hood over the exhaust manifolds. The person who painted the car before I got it didn't replace it. It has been several years and there is no damage to the paint under the hood.

My main concern was the heat. I bought a qt. of high heat black paint just in case. I'll just spray several coats of that. Thanks for your reply.

The 19-49 Ford factory parts manual does not show insulation used in the hood, only a a extrusion that is installed on the cowl to seal the hood to the cowl.

Apparently heat is not issue. I saw it mentioned once that it could also be for noise reduction which I don't care about.

Speaking of this stuff...what is the best adhesive to use to keep under hood insulation attached to the surface? I used the tackiest stickiest spray-on adhesive I could find, but the insulation eventually came off, presumably from the high temps. I used a couple lesser spray-on adhesives before then which didn't work well at all, even in the short term. This was on my Thunderbird.

Look at this - https://www.3m.com/3M/en_US/p/d/b40069451/

Make sure the under hood panel skin is clean (maybe wipe down with prep-sol) and masking tape the pad(s) to the underside of the hood to let the adhesive fully set. Leave hood opened maybe to allow adhesive to fully set before applying weight (hood closed).

This is a 55/57 BIRD?

... it could also be for noise reduction

That and at some point, under-hood heat may affect the outer finish.

Are there torsion bars on the '60 (I can't remember)? If so they are adjustable.

Thanks for the link, Kultulz, and the masking tape tip. I'll try that 3M product. My T-Bird is a '65.



As far as the trunk goes, my '61 Mercury trunk has the torsion bar setup, but I don't know about the '60 Fords or '60 Mercuries.

Yes, there are tension bars. Haven't gotten the guts to try and adj. them yet. Looks "easy" in the Ford manual. We'll see!!
