A coolant container cap assembly (10) for use with a coolant container having first and second sealing ridges (114, 142). The cap assembly (10) comprises an exterior cover for removeably securing the cap assembly (10) to the container (12). A valve housing (50) member is rotatably secured to the cover and has a lower housing portion (58) and an upper housing portion (56). A first sealing gasket (112) is mounted to the lower housing por-tion (58) for selectively engaging and sealing the cap assembly (10) with the first sealing ridge (112) of the container (12). A second sealing gasket (140) is mounted to the upper housing portion (56) for selectively engaging and sealing the cap assembly (10) with the second sealing ridge (142) of the container (12). The assembly is characterized by an ad-justment device mounted to the upper hous-ing (56). The adjustment device (70) allows relative movement of the first sealing gasket (112) with respect to the second gasket (140). Specifically, the adjustment device (70) per-mits the first sealinggasket (112) to detach from the first sealing ridge (114) of the con-tainer (12) while maintaining the sealing en-gagement of the second sealing gasket (140) with the second sealing ridge (142) of the con-tainer (12).
