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
