My Jeep is a 2005 model and i have only put about 1000 miles on it so far but the temp gauge reads about 210 or 220 all the time. The Jeep has 17,000 miles on it, 6 cylinder.
Is this normal for Jeeps to run this hot?

210 is the standard temp the 4.0 will run at. You dont' have to start worrying about it til it gets about 235 to 245 range. By then you will probably hearing coolant bubbling.

Exactly. About the only time it'll run closer to the 195 degrees the thermostat opens at is in super-cold conditions. :)

personaly, i dont like em running that hot.
180 is fine with me all day long. the heat is for emissions, nothing more.

You may personally not like it but that's how they're designed to run now. They actually run most efficiently at 190-210 degrees, and those temps don't faze the engines or the modern engine oils inside them. :)

260 is way to much i know from personal exp. when i blew my rad. i put a 180 therm in place of the 195 one and now my it runs around 200 which pleases me.

Since a 195 degree thermostat is already wide open at 195 degrees, let alone 200 degrees, how could it make a difference? My TJ runs right at just below to just over 200 with its 195 degree thermostat. :)
