Heater core leak

Question

Thanks for the suggestions. I believe I will hold off on ordering or buying a heater core itself. Winnebago rep told me to get the cap off and check out the entire box and hoses inside. Since it was the first time in 6 years the interior heater switch was turned on, it could be a hose leak. No smell, mist or anything inside. Just drips very slow while running. Lost maybe a pint in 700 miles. Lot of work getting to it, but just bypassing it, I might not get back to fixing it right. QUESTION: There is a small crack in the plastic box. Is it best to replace the entire unit if it needs a heater core. 16 years old.
Thanks....you are quite the group of knowledgeable people with "hands on" experience,
