LS1 Radiator hose
My LS1 keeps blowing of the lower radiator hose. What can be causing this problem. The Radiator cap seems to be working, Coolant was leaking out the overflow before the hose blew off. I have tried double banding and it still blew off. This happens about 30 seconds after you shut the motor off. Temp guage reads right arround 190.
