1. Ok, there is 2 retaining irons that hold the core to the face plate. from there we start by lining the outer edge of the fiberglass box with a roap sealer, dont use a thick gasket, you need something that will squish down flat so that the face plate can be mounted without stripping out the small screw bosses on the underside of the box.
2. you can use thick core donut gaskets or make your own gasket, or use the old one that goes on the core and around the core tubes. All this does is keep the core from vibrating against the iner sides of the holes of the face plate.
3. Now that the core is through the holes, face the plate with the core up in front of you on the table with the tubes uptop and facing twards you. Be carefull you dont mess with the tubes to much for the flux or solder will break loose, then you have a leak.
4. there are 2 support retainer iron brackets and one looks odd, because one side of it is angled inwards under the core, and the other is angled outward. This funny angled bracket is placed at the top portion of the core near the tubs to mount the core to the plate the inward angle of the bracket goes on the left site to mount, then mount the other one at the bottom using the small self tapping screws you took off before, if the bosses are stripped you will need to do alittle repair and use bigger screwes to tighten them down.
5. You dont wanna use any gasket or sealer on the under side or outer side of the core, its mounted tight and thats it.
6. Now hopfully you have the linner of the box sealled with roap sealer, BY the way if anyone needs roap sealer I can get them a bunch of it for 10.00 just email me, and I will setup shipping. This sealer can be used for anything.
7. Place the face plate back onto the box lining up the door flapper mechinisim to the box, then bolting it down. Your core should not move at all if its tightly secure to the face plate using the brackets. BTW, if anyone needs these brackets I have some extra. email me.
8. re bolt up all the small screws and make sure everything is tight. thats it. Also make sure your hose goes all the way up the tubs within the firewall to protect the copper tubbing.
