I had a minor leak this morning on my lower radiator hose. I'm using original hoses, but, I switched out to band clamps with worm gear because the wires were basically shearing the hose. I don't recommend doing what I did. Anyway, I wonder if they loosen up over time, mine was kinda loose? Also, I wonder how much force a Gano filter will take before it gives up? I'd say that your motor is healthy enough to not wear one. On mine, I just watched the rust flow thru it for the most part, but, the opaque 5/8" filter on the heater line was a bit more catching of stuff. A several gallon sample run thru a coffee filter on the bench didn't reveal much on mine, I bet it is still stuck, or whatever.
Just make sure your coolant has enough freeze protection for your current weather.
