Thank you for your offer on pictures. I recall you sent those out last
year when you did the job. Looked rather freakish to be honest...

For the two heater core hoses:
Getting them off at the connections to the heater core by the firewall
is pretty painless. The square tubing that connects the two strut
towers (what is this for anyway?!?) is in the way as usual, but no
The ends you're having trouble with are probably the lower ones that
go into the engine coolant pipes. Those were indeed a royal pain in
the a**. There's one that goes straight forward into a pipe. That one
is not that hard to remove. It takes some tugging, grunting, and
twisting but it will come off. The troublesome hose is the one that
has the U turn in it near the end. For that one, I found a way from
below to cut a slit in it that would allow the hose to slip off the
pipe/hose fitting.
