Mine is the '91 edition, some of my page numbers don't gibe with yours.

This agrees with my 19.10 (83-85 cooling schematic), 19.12 (all watercooled
radiator ass'y).  It also makes sense given that the fan thermoswitch is at
the bottom of the radiator, hence reading exit temps.

My 19.14 is a drawing of water pump-related stuff in the 2.1 engine...but
my 19.12 clearly shows the bent-end hose crossing over the straight hose
and mating with the left-side pipe.  This agrees with my van as well.  At
the after end my 19.8 and 19.9 (complete engine-compartment plumbing,
83-85) clearly indicates the hose connected to the pipe which enters on the
left (dunno if the pipes cross underneath but I doubt it) is connected to
the upper transverse hose which then enters the lower thermostat housing
and is protected by a small shield from nearby exhaust pipe.  This agrees
with the flow diagram on 19.10.

The discrepancy is that in the diagram on 19.10 they do not show the hoses
in front crossing over each other; however 19.12 clearly shows that they
do.  19.10 indicates that they cross over at the engine compartment, which
is not so.

Make sense?
