Yea got the bottom hose off. It was old and crusty and the clamps were both rusted and pretty brittle. Going to get a new 5/8 hose and some new clamps. Refill the anti freeze and hope that solves the issue!
Took the wife to the famers market today and a few miles down the road water starts coming into the cabin and spraying on my wife's leg. Looks like the bottom hose here has a new leak in it (you can see it is wet under the bottom). Assuming it has something to do with my heater? Wanted to see...
