Abstract
A non-pressurized fluid reservoir for a vehicle coolant system includes a bottle configured to store fluid. The bottle has a neck defining an inner circumferential surface that is devoid of threads. The reservoir further includes a cap having a lid and a shank extending from the lid. The shank has an outer circumferential surface and with a spiral ramp supported on the outer circumferential surface to encircle a portion of the shank. The shank is receivable within the neck with the spiral ramp adjacent to the inner circumferential surface to mitigate fluid leaks through the neck.
