After running around town last week in my Syncro Westy, I noticed that right
after I shut off the engine, I heard gurgling noises from the cooling
system.  I quickly ran to the back, lifted the hatch and noticed that
coolant seemed to be bubbling into the expansion tank.  It stopped after
about 45 seconds, and as I recall the level in the over flow tank appeared
to be normal.  This is the only time this has happened, and it hasn't
happened since.  Is this normal, or do I need to "burp" the cooling system?
Could it be a sticky thermostat?

PS - the cooling system, engine, hoses, H20 pump were replace about 25,000
miles ago.

Thanks
