Default Coolant From Exp Tank

Guys,
After I shut of my 427/435 it spews coolant from the expansion tank hose. Any ideas why? I have a new exp tank cap,radiator, and thermostat. The engine temp goes up after I shut off the car as well when this happens.Thanks for any suggestions

With the cap off, and the radiator cool, where is the coolant level when you look down into the radiator? It should be about four inches from the lip of the filler neck.

This topic was beat to death recently. If your tank is overfilled or the cap is bad, it will puke on the ground. It's perfectly normal for the temp to go up after shutdown.

The radiator on mine does not have a cap. The expansion tank has a cap which in new and the coolant level when cool was about half full. Thanks
