    Figure out if it’s a hose, or the filter, or the filter base. May have a hairline crack, happens a lot on fuel filter bases. Probably just a hose. Most have shutoffs on both sides of the filter. Does no good if a hose breaks. Need shutoffs at the supply point for the hoses, making it easy to change a hose, though might lose a bit when changing filters. Not a big deal. Maybe you can change the hoses fast, to eliminate needing to drain all the coolant. Catch what you can. Top it off afterwards. One long hose, to bypass it for now is another option. Maybe you just have a loose clamp?
