Been trying to track down a coolant leak on passengers side of engine. 2003 Monte Carlo SS. Thought it was the water pump replaced it still leaking. Thought it might be intake gasket cleaned area not leaking there. Inspected hoses cant find leak. Only seems to leak after sitting all night. It appears to be running down passengers side of frame and leaking on garage floor. Sitting over night puddle about the size of A silver dollar not very much. I suspect radiator so any tricks removing it? Thanks for any help on leak or radiator removal.
