Heater core Question

Ok so i bought my jeep back in the warm weather after i got it i noticed the heater core was bypassed so i figured it was clogged or leaking .and was gona have to put a new one in . so its starting to get cool at nights here in Kentucky and i decited to do the dreaded job of putting one in before i started taking the core out i said what the hell why not hook the hoses up and try it . Well i have used it 3 days about 100 miles and no leaks no problems it is very warm on low and like a furnace on high. Sweet i don't need to put one in now . my question is why would the owner before me unhook the hoses ? performance thing ? caint figure out why they were unhooked ? any ideas

I don't see how that would affect performance. Maybe it was running a bit hot and he thought that would solve the problem, which if it was hooked up and the heat was run it would run maybe slightly cooler. Or, there was a minor leak at the time. Since it's o'k leave it alone. If it does start to leak bypass it and decide if you want to replace it.

The previous owner may have thought that by disconnecting the heater core it would make the interior slightly cooler in the summer with the top on. The air box though has a gate to block airflow from the heater core so it really wouldn't be necessary.
