Yep, mine rides at just a hair below the 210 graduation. Anyways, when my Jeep is coming up temp and hits the line under 210 (like in the picture) my heat is like an oven as well.

Although 210° is a typical operating temperature for a 4.0L, it should be running at 195° under ideal circumstances, assuming you have the correct thermostat installed.
I was confused by the picture because that's actually a good thing

Both of my heater core hoses last night were cold, which leads me to believe that it's clogged, but shouldn't just one be cold? I guess if it's blocked, the coolant already in those lines can't move out of the way.
I saw a couple people used compressed air and soaking CLR to clear their heater cores. I am going to try that tomorrow and see what happens. I'll probably do the thermostat too if I have time. Any suggestions?
Edit: I am also going to have the system flushed by a garage in the very near future, my coolant is absolutely atrocious. I don't have the patience for the fill and drain method, and I think overall, the "professional" flush is a lot more effective.

Well, a new thermostat did not fix my low temp problem. I did boil it in water before putting it in, and it worked fine. I am going to try to flush the system Wednesday and see what happens after that. I do have a brand new radiator this year, I highly doubt it's too efficient but who knows.
Spent 8 hours yesterday on replacing my leaf springs. What a f*&^ing nightmare. most of the bolts were seized to the bushing sleeves, so we had to end up cutting the bolts, then welding nuts to them and turning them out. The front leaf spring bolts were so tight, we had to use a ratchet strap wrapped around my front wheel, then the other end attached to the breaker bar. I am never doing this again lol. Didn't have time for the fronts, might do them Wednesday at Jakes, or I will just do them at home, so I have to ride around forward rake style for the time being
