The rubber seal found at the top of the 1979-93 fox body Mustang firewall where it meets the rear of the hood is called, appropriately, the Firewall to Hood Seal. It is constructed of EPDM rubber and has a felt faced side that touches the hood, and the other side has bonded metal clips for attachment to the firewall.

The purpose of this seal/weatherstripping is mainly to seal off the engine compartment to allow a low pressure area to develop in the engine compartment while driving so that air flows properly through the radiator. It also serves to keep constant water intrusion off of firewall mounted harnesses and components.

Follow the steps in the video above to remove and install your new weatherstrip!

SPEAKER 1: '79 to '93 Mustangs have a firewall-to-hood seal. This weatherstrip seals off the seam between the hood and the cowl panel. Now what this thing does, it keeps water from intruding into the engine compartment as well as keeping in negative air pressure in the engine compartment so air will properly flow through the radiator.

Don't ask me how that works. Its way above my pay grade. This is what I was told from a Ford engineer.

Now what causes these things to fail is the rubber gets completely brittle, breaks, cracks, falls apart, and no longer performs its function. Now removal is simple. It's held onto the firewall by just a series of clips that you can pull up, and remove the seal from the firewall. Once you get all of your clips disengaged, you can go ahead and pull your old weatherstrip out of the way.

Our new 5.0 Resto Weatherstrip is an exact replacement for the original. Correct rubber, has the felt bonding on it, and all the original style clips. Go ahead and slide it into place around your hood hinges, and start engaging all of your clips, one at a time And you'll feel them engage. They'll actually pop into place.

And there you go. Brand new firewall-to-hood seal. Completely restores the function. For more under-hood restoration items and tips, check out latemodelrestoration.com.
