I'm afraid that is what looking at (the head/gasket).. I really hope it stops there. That makes sense with your symptoms but mine is pretty consistent in how the temp spikes so I am doubtful of the sending unit yes, It has a "16" stamping on it.

--UPDATE-- I just got done changing out the water pump, and temp sensor. While I was at it I took the thermostat out put it in boiling water to make sure it was operating as it should (it is), I made sure there was a spring in the lower hose and I did a one h3ll of a flush (have you ever cleaned...

Thanks man, but I dont think that is the same that I am experiencing.

radiator is new (<500 miles on it). I cant see any head damage from the oil fill cap, and there is nothing on the dipstick but oil. Water pump isnt leaking. T-Stat is only ~1 year old I bought the type that 'should' fail open. I've seen pics of completely corroded vains on the water pumps...

gradual

yes, the rapid change of the temp reading.

thanks for the quick reply, I agree that it shouldn't be running at the elevated temps; it idles fine (~205*). Strait flat runs it gets up to ~215* when I come to a stop the temp drops back down. But the drive up US 89 past your house up to ogden is enough to get the temp over 220* and spike...

I was doing some more reading and came across this thread: http://www.naxja.org/forum/showthread.php?t=1101664 see post 4: Has anyone else heard of this? Dr. Moab, do you know what years this may apply to? If this is true than I think I may have a water pump on its last legs and when it gets...

I'm on my second radiator cap, i doubt both are bad. As for the water pump, it could be dieing... but as I said on my original post a dieing water wouldnt cause a rapid change in temp like I'm seeing, it would be a steady climb and drop, right?

Here is the long story on my coolant system; About 2 months ago I was on a drive ~an hour from my house and a blade on my electric fan fell apart (just old and brittle) and made some god awful noise. I pulled over and removed the remaining parts of the electric fan. I drove it back home but it...

I completely agree with the law of physics pot of view, but all those ideas would cause an intermittent temp spike, my jeep is pretty consistent on when and how it overheats. That would lead me to believe that I have a real issue not just a faulty reading. I think the Temp / Pressure / Boiling...

I posted this question to jeepforum.com but it was essentially received with crickets, maybe you guys can help. BLUF: Temp will jump from ~220 to 240+ in about a second then after a couple of minutes pulled over it drops back down to from 240+ to ~215 in about a second.. and I dont know why...

Apparently not ;) ... got one in the mail now! Thanks

I just sold some old parts and now Im looking to pull the trigger on a locker... Does anyone know where I can get a good deal on a Spartan, the 8.25" 29 spline variety? Thanks.
