The Z1 Offroad Non-Pressurized Radiator Overflow Cap is indented to go onto the radiator assembly.

This cap is intended to be used on the radiator of these models. These models use a standard un-sprung flat cap on the radiator and instead use a pressurized radiator overflow tank to store excess coolant. It's important that you DO NOT mix up the position of these two similar-looking caps when installing.
