how much does underhood pad do?

[dodge man]

I wouldn't worry about the heat, its more to muffle the sound than anything else. I'd also look at another product, like someone else said, Dynamatt.

i pulled the pad off at lunch ... It's probbaly a gonner.. but I have it laid out on the concrete at the shop and liberally .. and I do mean liberally treated it with purple stuff, dish soap and laundry soap and am letting it set there and think..

the innards of the engine compartment and the under side of the hood got scrubbed again at a car wash that had a hot water and medium pressure wand plus a pre soak foam, and a tire and engine cleaner foam.

used that.

then came home and used some more dish soap and laundry soap to clean the plastic around the grill on the vents...

starting truck she seems a hair louder.. might be able to live with it..

i checked my 6.0psd 04.. it has no pad.. so i'm thinking the heat will be a non issue to the paint.. just the sound..

hood has a deep molding to it and fits down over some pointy parts.. so whatver i put on needs to fully form fit to the underside of the hood. i may be able to cut a smaller piece of some sound proofing felt padding and put it on the section of the hood right over the engine before it makes the bends int he hood to make attaching easier.

dunno.. gonna think on it a few days and see what materials I can find.

I don't want to invest more than 50$ as if i'm going that far for a compromise pad.. i might as well save up the lunch money and get the real thing...

will see

It's funny reading about the measures you are going to to clean diesel off your truck. Makes me think of a couple years ago when an older neighbor would intentionally spray the underside (and I believe engine compartment) with diesel as rust preventative. He was trying to tell me that I should do the same. No thanks. :laughing:

id either run no pad or go to junkrard!

Just leave it. I just checked my trucks and non of them have one and also my neighbors Dmax came without one.

Foil faced foam board?

Won't take the heat and could add fuel to the fire ...

Glass Fiberboard may be the material to use. Try a HVAC supply place.

My job at one time was to design that hood blanket. It is there to absorb high frequency engine hash heard in the cab, plus to minimize noise on a government mandated pass by noise test. I'd say drive it awhile and if it is too much louder, pick one up at a junk yard.

it's parked inthe driveway again.. I plan on using it till :

a, the noise bothers me.. which.. I doubt it will.

or

b, I find a cheap pad.

there is a junkyard on my way home i may stop in and ask to see if they have a pad for S&G's

How about using some duct insulation from some heating and air place. Use your old pad as a template and cut to fit. It has to be a lot cheaper that $200.

A neighbor of mine uses that stuff (looks like foil bubble-wrap). Seems to work fine, and isn't that expensive.

well.. ran truck for first time since mega cleaning and pad-ectomy.

other than the overwhelming coconut smell from the new freshner I put in.. cab smells good. I can also roll down window and not be fumed. have not tested ac or vent as it was too cold to do so on way to work.

double checked fuel filter housing for leaks again.. bone dry.

so far so good.. but need a ac vent test and vent-vent test still.

noise is just a hair over normal.. and I imagine.. within tolerance.. pad wasn't doing much I guess..

will post back more.. only driven it 12m since super scrub
