rear heater can leak from:

-hose connections to heater - there are "Ts" that split off from main
heater lines that run from engine up to front of van. These Ts are
under the van, at a location corresponding approx. just in front of
right rear wheel, scrooch under van and have a look
-leaky hose itself (rare)
-bleeding screw on heater valve leaking (has an o ring in it)
-leaking between valve body and core (again an O, or square section
ring involved)
-core itself leaking

At the risk of sounding like my usual self, one of the first things
you need to do this weekend is buy a Bentley manual. Seriously, you
will be needing it if you plan on keeping the van.

There does seem to be another leak in the rear heater lines somewhere
and I
have yet to find it. I can smell antifreeze/coolant when it gets warm
and I
keep having to add a little coolant every week or so. It's obviously
a small
leak, so that's fortunate in some ways, but it's dang annoying! Nothing
under the rear seat is wet so it's not located there. It doesn't seem
to be
in the engine compartment and I don't see any drips or puddles under the
van. Any thoughts on where else to look?
