Under hood insulation

The under hood insulation serves a few purposes
1) in the event of an engine fire, the plastic retaining clips melt which allows the insulation to drop over the engine and smother the engine fire
2) sound deadening
3) protects the paint from heat of the engine
4) allows the heat of the engine to dissipate

 

Never thought of point 1.

 

I started fighting fires at age 15 and still am at age 57 Volunteer and Career and I have never scene point 1 work.

 

Thats supposedly the main reason for the insulation. To snuff an engine fire

 

O.K. What material would you use to replace (missing) factory underhood insulation? I have the plastic retaining clips but don't want to pay for a Toyota OEM replacement. Something I can cut to fit?

 

I replaced mine with this just because it was torn up and looked like crap.

Thanks JustADriver for the link https://www.ebay.com/itm/363036913589
I just ordered one

 

That eBay link says for 95-00 models, would it fit 01-04 models? I know the hoods themselves don’t interchange but the mat should have more leeway maybe?

 

I had the same question but just assumed the fasteners wouldn’t line up with anything on an 01-04 hood.

 

JustADriver, how do you like the product? Seem decent, fit well, etc?? Thanks

 

I’ll give a follow up report once I’ve received it & installed on my 2000 PreRunner

 

Sounds good.

 

Yeah I got it like a year ago. Fit is good. Clips are good.

 

Appreciate your response.

 

I replaced mine with thermal acoustic foam. Just peel and stick. It has lasted for 7 years at this point without any issues, though the throttle cable rubs against it just like the original liner. https://www.designengineering.com/under-hood-thermal-acoustic-lining-32-x-54/#product-reviews

 

All due respect, I’d rather have the clips that would melt in the event of an engine fire, and snuff out the blaze

 

I have a 10-lb fire extinguisher in the cab. I don't see how the hood liner could effectively choke off oxygen from a fire. The position it's in when the hood is closed would be almost unchanged without the clips, and air can still enter from below.

 

Mine fell of long ago and have been running without one for about 8 years. Didn't notice a difference besides less crap on the top of my engine from the old one disintegrating.

 

I have insurance! If you got a good fire going it might keep the paint on the hood from blistering.

 

That's because it's pure urban legend.
