By now it needs head and intake gaskets (upper engine gasket kit & if high miles rebuild the heads and/or have heads resurfaced and checked for cracks aka pressure tested). Find all hose's and radiator leaks and repair or replace and your overflow coolant reservoir cap (if reservoir is leaking replace it) and bleed out all air from system and check/test/replace thermostat.

If you have the Northstar engine it's probably going to be the head gaskets. All Northstar engines blow head gaskets sooner or later. Have the coolant tested for exhaust gases to confirm this. HTH. -Jim

Why does it leak so much in the grintvof the car but under
