Coolant Bottle Cap and Radiator Cap.. the same?

[wntsom4]

Are the radiator and coolant bottle caps the same... I haven't paid close attention to them but I know either my cap or the coolant bottle is leaking....

Any knowledge on this would be great.

There is no cap on the radiator, so it should be the coolant bottle cap.

Check the bottle as well for leakage. A common accurance.
