2004 LB7 Duramax

I just bought a 2004 Duramax LB7 with 200K miles on it, the injectors were replaces way back under warranty. Today I drove about 1.5 hours at 75 mph the coolant temp did not break 175 but the coolant tank surged once and came out the overflow hose. is this something that I need to worry about?

I'd check for a possible head gasket failure.

Let sit over night the upper radiator hose does not feel hard and I can squeeze the hose over half way collapsed with little effort, drove it about 70 miles and nothing else has come out the overflow hose.
