Where do i add radiator sealant in 2000 saturn?

On a 2000 Saturn you should probably replace whatever part is leaking rather than gum it up with a sealant. If you must use a sealant you would remove the pressurized radiator cap.(This cap may not be on the radiator on all models. It may be located on a plastic surge tank located separate from the radiator.) Once the engine has reached full operating temperature add the sealant in to the rest of the coolant. Top off the coolant and replace cap. Run engine or drive for 10 minutes. Then shut the car off and allow to cool completely. NOTE:Radiator sealants will not stop leaks of rotating shaft seals(water pumps). Additionally, modern engines such as the ones used in Saturns have tight engine clearances and small water passages through aluminum parts. Sealants are a safe bet to use on the over-sized cast iron engines of days of yore, but a modern engine is isn't made for that kind of gunk surging through its veins.
