97 Intrepid 3.5 coolant leak

Can anyone tell me what could cause my entire coolant to suddenly leak out from under the motor of my 1997 Intrepid 3.5 with only 125 000 KM.

Pressure test shows the rad and heater core with hoses are okay.

Is it possible for the culprit to be the Intake gasket?

-Thanks.

Have you checked the water pump??? Freeze plugs???

Water pump and plugs are okay.
Changed the intake gasket and a couple of messed up bolts. So far so good, keeping an eye on it for now.
