Hello again, there are several different brands of the epoxy made for this use, a little bit bigger than a package of cigarettes.
Ask one of the more experienced looking countermen to show you the options... you want a 2 part epoxy mix for those socket fittings, not a hot melt.

CLICK HERE FOR ONE OF THE REFRIGERATION/ ALUMINUM/ COPPER RATED EPOXY KITS.. there are several others ask the counter man which one they carry and sell the most of.
Both of these stores carry the special flux coated welding rod made for aluminum, read the package as to what temperature torch is required.. anything that melts under 1,000 deg F can be done with a map gas torch from Home depot... tell the counter man what materials are involved all aluminum or copper and aluminum, he will show you the relevant products. I recommend the epoxies though.
Before you disconnect the old evaporator coil it might be a good idea to tell me why you are replacing it. The only valid reason for replacing the coil is if it has a refrigerant leak or corrosion that leaks... otherwise if it does not cool the problem is a bad solenoid valve, thermostat, or clogged capilary tube that feeds the coil
Let me know about that.
