Rebuild Thread
But at these points, on the cowl and down towards the top of the Turbo, I didn't have any clips or anything else holding the fatmat in place either. It was just installed using the sticky asphalt backing to the bare metal. Now, Behind the trubo on the firewall, I did as you did using the threaded bolts that are protruding thru the firewall. I attached the Fatmat here as you did, and used some 2" flat washer to help hold the Fatmat in place down the firewall, and for the most part, the fatmat did stay in place down the firewall and towards the seam at the transmission. What I ended up doing about 4yrs later, because the fatmat kept peeling off in those areas I described, was I fabbed up some 5"X8"Aluminum diamond plates that I shaped to the area behind the turbo and 2 more to either side of the turbo, drilled holes in them and again using the bolts that are protruding the firewall, I set the Aluminum plates in place. This helped to cover a bigger area of the fatmat and this did hold the Fatmat in place. The other idea I had was to make the Aluminum plate/plates much larger, to go the entire length from bolt to bolt say about 6"W X 24"L +/- or so because I don't remember the length of this area rightnow, but to cover from bolt to bolt, and install this aluminum diamond plate on the firewall right behind the turbo area. This to will hold the Coolitmat in place.
Lastly I'm not sure if you decided to reinstall the OEM heat barrier over the Coolitmat, but I didn't see where you did. I believe I saw that you had applied the coolitmat to the cowl above the turbo area, and unless you use some sort of clips or plate's to hold it in place, it will peel off. Here in the last 4 months I ended up removing the Fatmat from the cowl and down to just behind the turbo. It was a pain in the butt to remove the black asphalt adhesive to clean metal as well. I then applied the Second Skin mega block (Amazon) from the hood seal-Top cowl all the way down to the transmission bellhousing, to cover the Fatmat as well. This seems to be holding in place very well.
In the picture below, from about where the nuts and washers are to the cowl/hood seal is the point from where I had to remove the Fatmat, because it kept peeling off. From the nuts and washer's down to above the Transmission I left the Fatmat in place under the MegaBlock.
I apologize for the long post, I only wanted to share some info with you about this type Coolitmat/Fatmat etc. It's great stuff for sure, It's just not going to hold up in the areas I described. About the same time, I gutted the interior of my truck and installed the Fatmat thu-out. I also did inside of the 4 doors and it made an amazing difference in the road noise, as well as to my stereo system. It sounded as though I had installed a new stereo system bigger, thicker, tighter bass, and the highs are just amazing too. Again, sorry for the long post. I'm in West Texas, Pecos to be exact.
What I bought but haven't installed is Thermo-Tec Cool-it mat. I'll be using the existing clips on studs to hold it in place. The melting issues may have been why Ford did not use an adhesive mat. But without history, I can say how it would hold up.

The tape that I used in the seams within the picture I posted is Thermotec.
This stuff is like Frank’s Hot Sauce...I put that **** on everything.
