摘要: A hydrometer unit permanently connected in an engine coolant line enables immediate visual check on the adequacy of anti-freeze constituent, such as ethylene glycol, system. The includes a receiving chamber having transparent viewing portion and number variously colored float elements within provide accurate indication strength based specific gravity. No manipulation is required to enable checking or weakness anti-freeze.
