Long time reader, first time poster. Very appreciative of all the knowledge poured out on these forums.
I hope ya'll can help. I've tried everything!
Jeep TJ 2.5 bought used in 2020 with about 130,000k miles on it. Drained the coolant and started doing flush cycles on it with distilled water and radiator flush chemicals. I have probably ran Presetone radiator flush 4-5 times and Thermocure at least twice. With the Prestone I would leave it in a few days and then flush out. With the Thermocure, once I left it in a few days and another time I left it in for about a month. Between those chemical flushes I have run countless gallons of distilled water through. It is not a stretch to say that I am over 50 flushes, does this put me into crazy territory?
Early along the way I replaced most of the cooling system after the radiator developed a leak - radiator, thermostat, water pump, hoses, gaskets. I am at my wits end on this. I am ready to button it up for the winter and put some coolant in but just can't bare to do it with the water still coming out muddy brown almost every time. More recently I did back flush the heater core and even tried a flush cycle with white vinegar.
Most likely rust in the engine block. Any other ideas to try? Should I just move on and try another series of treatments in a year or 2?
