Hi Larry,
I've never worked on a 602, and my 603's are similar, but not
identical to yours. Anyway, here's a couple of possible tips:
1) I can R&R this from up top - I pull the rubber intake snorkel
(loosen the one clamp on each end), and that provides lots of room.
There's also access from below if you're having a hard time from up
top.
2) If there is a round electrical widget directly in front of the
housing, remove this first... it makes the job about 10x easier. I'm
not sure if the 602 has this sensor or not (may depend on model year).
On my car this is a 50C switch for the tranny vacuum circuit, with one
wire attached. The seal is re-useable.
3) There's a block drain under the turbo, near the motor mount
bracket, just above the oil pan. Loosen this 19mm fitting to drain the
block.
4) The front sound panel is attached with 4 screws - pretty simple. If
any of the "nuts" are stripped, you may be able to fix them with
pliers and a vise... I keep a bunch on hand though and replace the bad
ones periodically. They're pretty cheap from Rusty,
:-)
