2006 Cadillac STS Q&A
2006 Cadillac STS Question: coolant leak
Was the gasket surface cleaned properly? Make sure the surface is not damaged in anyway. Did you use the gasket "dry" or did you try sealer like the Right Stuff by Permatex or other similar sealer. The way an automotive shop would locate the leak is by removing the radiator cap and attaching an adapter that screws on in place of the radiator cap. Something that looks like a bicycle pump with a pressure gauge attached to it is used to "pump up" pressure to simulate pressure generated when the cooling system is at operating temperature, the leak is then found sometimes it is obviously leaking from a coolant hose or cracked housing, failed gasket or water pump, sometimes the engines cooling system needs to be inspected from below or inspected using a mirror and flash light. - patrick mannion
