2001 cherokee overheating and uses coolent for 3 years despite repairs
Please help with ideas, advice or hints, I would really appreciate the help. I have a 2001 Jeep Cherokee Sport that overheats and uses coolant.
Started with a major overheat in 2008--had new radiator, new water pump, new thermostat?, new radiator cap, fan clutch, new head gasket, and head checked plus flushed many times all by mechanic. He even changed or fixed the heater core. $1500 and still overheated occasionally. Changed to G-05 antifreeze. Driven very little since then, had to get another vehicle.
Less than a year ago my son starts to drive the Jeep, driving 4 blocks to school and about a 10 mile one-way trip on weekend. Continually adding water and/or diluted antifreeze. No apparent antifreeze leak spot/place, no white smoke, no antifreeze in oil. Occasional overheating, but stopped driving immediately and cooled jeep off.
Then ticking noise--bad lifter. My brother, a very experienced home mechanic, dismantled engine cleaned it replaced all lifters, all gaskets including head and valve, oil pump, water pump and anything else he thought it might need, he inspected heads,cylinders and block.
Still used antifreeze, have used 2 gallons of G-05 antifreeze (50/50 diluted, of course) in 3 months. Now 3 months and not even 500 miles later...overheated and blew new head gasket. We cannot figure out why it overheats and uses antifreeze.
I have read many posts, but none where problem was still not solved after all of these new parts or problem was solved. Only thing we haven't tried that I read about was the thermal temp camera which I will ask him to try after he replaces head gasket.
Any other ideas on what could be causing this? Please help if you can, my son loves the jeep, but I can't keep putting all of this money into it and it still not work right.
List of major repairs:
Serpentine belt replaced
manifold recall fix done by dealer prior to 2008
new head gasket, head machined, inspected ect...
new water pump
new fan clutch
heater core replaced or fixed
engine thoughly flushed
sepentine belt replaced
new power steering pulley
new power steering pump
new gaskets including new head gasket, valve gasket ( no apparrent damage to old ones, replaced since was already in there)
new water pump

Any help with possible overheating causes would be greatly appreciated. This is driving me crazy and it is such a shame because rest of Jeep is in great condition.
Thank you so much.
