[s-cars] 1995.5 S6 coolant loss issue resolved

[Daniel Hussey]

I just solved my slow (but quickly growing) coolant leak!  Yes, everyone out
there replace your explansion tanks!!!  I replaced mine last year, but had
it happen on my 5000tq and dump coolant all over the ground when parked one
day... rather unpleasant experience and could have been worse if I was
driving it at the time.  The S4 tanks aren't cheap (about $75 from the
dealer)...  Rod @ TPC has them for $50.

My leak however was coming from the back end of the after-run coolant pump.
There are two mated plastic pieces and I think the gasket in there blew.  It
dribbles coolant a bit when parked and pisses some when I drive it.  I top
it up before I go anywhere and keep coolant/water in the trunk.

Rod hooked me up with a new one and I should have it this weekend to change
out.  I was under my car last night and all my radiator hoses (lower ones
anyways) are feeling old, stiff, and brittle.  I think it's time for a
complete flush and overhaul.  Anyone know the procedure for properly
"flushing" the radiator???  I've never really used flush in it before, but
drained and refilled it.  You guys think that will be enough again?  I heard
the fush stuff can cause havoc in the cooling system.

Later,
Dan
