It's possible that you have air or combustion gasses in the cooling
system. Either will cause the coolant to get pushed out of the pressure
tank causing the low coolant light to come on. It can also cause the
coolant to stop flowing causing intermittent temperature problems. Make
the sure that the pressure cap is also working. Although you have new
heads, you may still have a problem where the heads meet the cylinders.

Subject: flashing coolant light

Hi All,

My '87 Westy is giving a bit of trouble and I am hoping for some help
determining the problem.  When I warm her up at the start of the day,
her
coolant light comes on after a couple of minutes.  If I turn off the
engine
and restart her, sometimes the light will stay off.  This just started a
couple of days ago.  Today while driving to work, the gauge kept
creeping up
until it was almost to the top then the light came on.  I shut her down
and
restarted.  The gauge went down to normal and the light remained off.  I
just had the heads replaced two months ago along with a new radiator,
and
thermostat.  Any ideas?  When I check it, the coolant level is fine.
Thanks in advance for any help.
