Replacement Pressure Cap (aka radiator cap) with for the GoWesty Aluminum Expansion Tank. If you have our all-metal tank and somehow lost your cap (or yours is defective), here is the replacement you need.
Options: We offer two distinct styles of cap depending on which generation GoWesty Aluminum Expansion Tank you have. Our earlier version featured a cap with a red pressure release lever, and our current version (black powder coated) features a standard flat top cap with a yellow warning label on it. Please select the correct cap for your tank in the drop-down menu.
