I thought the heater core was normally accessed through the firewall?
Depends on the car. MOST are now accessed from under the dash. Worst
one I experienced was on , IIRC, an XJC Jag. Book time was well over
12 hours. In the instructions, the first line was "remove parcel shelf
from behind rear seat". Then you removed trim, piece at a time as the
screws were exposed untill you got to the dash board, which took a few
hours to dissassemble and remove before you could even SEE the heater
box. Then after dissassembling the heater and replacing the core
(might have been AC condenser - cannot remember) the long and tedious
lob af reassembling the dash, and then re-installing all the trim
began. The mechanic who was working on it (a british car expert who
worked for me for a while) managed to pull the job off in about 8
hours - it wasn't his first time!!!!

One of my coworker's solutions on his personal vehicles was to
just cut whatever plastic was in his way in the engine compartment.
Duct tape and maybe silicone sealed things back up. He doesn't drive
fancy vehicles by any means.
Mid sixtied GM heater MOTORS required removal of the front inner
dender to get to - which pretty well meant you removed the right front
fender. We used to cut a hole in the inner fender to get the motor out
and bolt an old licence plate over it.
