Not so good! I have this on one car; the engine oil cooler has corroded inside and oil (80PSI) forces its way into the coolant (14PSI).
Best to fix the cause ASAP and then comprehensively flush the coolant, as leaving too long will cause the hoses to be dramatically weakened - leading to failure after failure. Been there, done that as well.

Is the tank (which you called expansion) located on the left side, behind the battery?
Could it be the LHM tank
