So I've done a search and can't pin down the issue.
This is a 2001 Cherokee. Automatic with the 4.0. That said, previous owner installed a 97 motor due to head issue and swapped water pump, radiator, hoses. About 180,000 on it, maybe 100,000 on motor. I don't know about the fan clutch(???).
That said, my daughter is driving the vehicle from Augusta GA to Dallas tonight. ON the way here to the Augusta area, the truck was overheating but she would fill up the overflow bottle which was emptying itself. When she got here, I drove it after putting on a new radiator cap and topping off coolant. No issues. She's been driving all day now and it just overheated outside Dallas. Overflow empty. So it went about 950 miles. She not much pressure on the upper hose so she (with towel) opened cap to first dedent and said that there was fluid coming out so she secured it. Car has cooled down so on the road again.
OK, so when I had it here, putting coolant in the radiator was kind of pain, it wouldn't really fill fast. Put a little in, it comes up to the neck and then flows down. Repeat. My thought was that there was air in the system and it was drawing the coolant out of the overflow over time. So I was told to take cap off, had it running and squeeze bottom hose to burp it. Did that, couple of air bubbles, but nothing major. Did this for about 15 min or so. It ran coolant stayed level in radiator neck. Maybe thermostat not opening? But if that's the case, it wouldn't have made 950 miles...
No leaks, oil dipstick is clean, new oil and the oil refill cap had no milk shake in it.
I'm at a loss why the overflow keeps emptying, no leaks evident, no smell of coolant inside the cabin or in the engine.
BTW, before she left, I had it up to temp and the gauge was a tick below center. Now it seems to be a bit above center but of course when it heats up, it moves to the right.
Thoughts greatly appreciated.
