Having tackled this one last summer, I think I can answer some of your
questions.
1. Oh hell yes.It'll be gooey and wet in there. Be careful not to rip up the
foam lining on the door flaps. I apparently did and now there's always some
warm air leaking in. Only when AC is on is it not noticeable -- if you know
to look for it. Old foam+glue =delicate.
2. Nope.German engineering.
3. Stop leak = glue = mess. Leave it alone. When you see what comes out after
draining a system it's been used on, you'll never consider it again.
4. Sure, but a length of flexible hose would be best. It's tight back there,
so being able to route it around without pinching or rubbing firewall would
be best. I used a brass connector, and didn't see any real corrosion on the
connector or scaling. You plan on getting to it relatively soon, so I
wouldn't worry either way.
5.Sure.
