Have you looked in the Family Album--the parts diagram should
indicate the orientation.  I doubt that it makes a big
difference--assuming _all_ connections can be made (vacuum hose and
electrical connector must be able to reach.) It's possible that the
heater valve will seal best when coolant flows in the "correct"
direction, but I can't imagine that would be a huge issue (well, I
guess you wouldn't want your A/C to be fighting a trickle through the
heat-exchanger all summer). The other possible "issue" is that the
temp sensor will be on either the heater side or the engine side (of
the valve). I suspect it's supposed to be on the engine side, but
I've never understood  exactly how that sensor is used anyway.
