We have a brand new radiator, but high pressure caused coolant leak under the radiator
hose clamp. Our mechanic found high pressure, tightened up clamp and checked head
gasket as reason for high pressure, but did not detect any leaking. Car is not overheating.

Define "high pressure". Modern cooling systems operate at around 15 PSI at normal operating temperature (195°F). HTH. -Jim
