It's called a Perry water filter. Inside would have originally had a sock element and a sacrificial plate to protect the cooling system from electrolysis. They've been obsolete for years. You can easily upgrade to a new spin-on style coolant treatment by purchasing and mounting the filter head and spin-on element. Contact Dane Baldwin through this forum by private message. He has new old stock if you choose to keep the original look.
