how much does underhood pad do?

Soundguy · Nov 8, 2012

the biggest issue i see trying to retro fit something is that the pad seems to be a tad 'molded' or at least stiff and flat and conforming once you punch in all the lil black holders.. something soft like a insulation blanket is gonna droop.. and i can see there is not much room for droop.. the screw connectors on part of the turbo pipe already make dimples in the oem pad as it is

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

Turn the heat on it still blows through the vents, or just turn on outside air blowing as a "vent" setting. You dont have to run ac to have air blowing at you. I guess you in FL forget that!! hahaha.

how old is that truck? my guess is that some big junk yard has one of them in it?

Soundguy · Nov 9, 2012

it's a 99. I havn't checked.. but not sure if all ford hoods of that era for trucks ar ethe same / same pad or not.

i'm wondering if a junkyard will sell a hood pad sans hood?

did the vent, heat and ac test today.

98% clear.

in fact. i smell a lil cleaner and cna't hardly detect any diesel. after 2-3 minutes. it's clear.

I'm way happy!

If you can find a hood that has been crunched a little, so not much value for resale, they would likely make good deal on the pad. I think your pad should clean up OK though. I have had the very "pleasant opportunity" to get a bath in hydraulic oil or diesel fuel from time to time. Wife loves it when that happens, but to clean up clothes I douse them in Mineral Spirits then a good fresh water rinse. Hang up outdoors to dry then soak with storng concentration of Dawn dish soap & water, rinse and hang to fry again. Repeat the Dawn treatment again if necessay.
It needs to hang so none of the diesel or cleaner can stay in contact with it as it dries, clothes line with some spring clamps to hold it up would work good.

yep.. bad is out back with a hole bottle of dawn and era laundry detergent on it.. plus a mild mix of purple stuf. hanging now.

i don't give it much hope.. but it was cheap to try.

hadn't thought about a dented hood. that might be a cheappy.. will call around on monday.. thanks for the idea

I always thought the hood pad was to keep noise down and protect the paint on the hood. It was my understanding that the hood would get hot enough to bake the paint off the hood from underneath.

If my understanding is correct you could try going to a stereo shop and get a few sheets of that sound insulation stuff that is stick on. foil backed its supposed to reflect heat also. Not cheep but in stock and perhaps cheeper than replacement pad?

If I may suggest: Buy the hood, too, and use it as a stone boat or to raise tree butts out of the dirt when dragging. An added advantage is that you will be able to remove the pad from the hood at your leisure.

As I mentioned, I used to design these things. There is no heat function, other than you don't want it to sag onto something really hot.

To achieve its acoustic function, it has to be soft and absorptive. The intent is to absorb high frequency sound waves rather than reflect them.
