Look to see if you have air bubbles in the clear tubing that goes around the
engine compartment. If you see bubbles flowing there, you have a head seal
leak and exhaust is getting into the cooling system. If forces coolant from
the main coolant tank into the expansion tank. Been there, done that. New
seals fixed it.
