2001 Cadillac V8 ( northstar) I start by letting vehicle cool down completely topping off fluid. pressurizing system cold! With pressure tester (Do to expansion contraction when Block is Hot sometimes cracks are harder to find and leeks slow) get underneath car look for drip find drip wash clean with brake clean blow dry with compressed air .video crack for customer you can see the white caking residue from evaporating antifreeze. This can be caused by multiple things I suspect head gasket being done and bottom of head bolt holes not being clear of all!! fluids. Best thing to do for this engine would be head studs and new block! Work safe and be careful this is all just suggestions help for you! for diagnosis I am not liable For any injury to self or vehicles.
