    2002 Jeep Wrangler Sport
    2002 Jeep Wrangler 110K miles V6 manual, no A/C- I had a leak in the radiator and noticed that the coolant was brown muddy water. I replaced the radiator, thermostat, water-pump, radiator hoses and 1 heater core hose (All original). I back-flushed the heater core and flushed water through the engine block. Refilled with new coolant (orange), ran it for about 30 min, held temperature and no leaks. Went out next day to check coolant level in radiator and the muddy water/sludge is back. There is no white smoke out the back that I can tell. Oil looks normal, no milky appearance. I am at a lost as to what to do next? Any help would be great.
