so this weekend i was taking my jeep up north , when i realized i was over heating , so i droped my speed and then the temputure dropped, so i continued on and once i hit over 65 it started to warm back up, so i slowed down and it cooled down, why is this happening!

check ur emergency brake ain't on, it sound like something is slowing it down @ high speeds, I'd look @ the brakes or trany

How far north were you ?? If you you were in below freezing conditions, and you didn't have enough anti freeze, it is possible that you were putting enough air through the radiator that it was Freezing the water (actually it would be more like "jelling", -as it turns 'mushy" with ice crystals). If it gets too thick to flow anymore, then the engine starts to overheat because of lack of water flow! If this was the case, - partially covering the radiator would have made it run cooler (in this case), - as it would have aided water flow! I have had this happen several times in my life, - when I was too poor to invest the extra money, or had a broken hose (repaired while I was on the road), - anyway ending up with insufficient antifreeze mix to be the way it should! One year the expenses got the best of us and with a wife and three kids - in Wisconsin, the radiator would freeze every day the temp was more than 30 degrees below zero! I would start the car and let run (slowly) for about a minute, - then shut off. Start after about another minute, and repeat. After the 3rd or 4th time, - enough heat from the engine would thaw the crystals so the water could flow through the pump, - then idle for about 5 minutes and I would go! That was a year that the anti freeze factory burned down, and anti freeze cost $15 a gallon (it took 2 to fill it properly),. Gas on the other hand was only 36 cents a gallon. I know for a fact that I didn't burn $30 worth of gas warming the engine up that winter! And of course the heater was "cozy" by the time I got in to drive. Only a "far north" resident can appreciate this!!

probably low coolant. The faster you drive, the higher the motor temp goes unless your coolant system is in perfect working order.
When your engine is cold ( let sit over night ), check the level in your radiator .... the opening on top of the radiator that says "Do Not Remove" when hot. If it's low ( not up to the top ) pour some more coolant in it until it reaches the top. If it still gets hot at higher speeds, check the fan on the radiator. Is the coolant fan electric? If it is, it could be the sensor that turns the fan on and off.

you could hav low coolant (antifreeze) or a brake is locking up when drivin, causing friction and friction=heat. Also, if your oil is bad, or if you don't have enough it will really heat up your engine.
