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!

It could be .... Thermostat or Radiator problems or a belt is not turning properly, check your water/coolant level. You can keep the temperature of the engine down by keeping the heater in your car on and roll your windows down if your too hot. Do not let this go...you could cause a crack in the engine block if you drive it too long while it's runing a HOT engine. Go get an estimate...and see what they tell you the problem is...then go for the best price....and you can also go to your local Collage to the Auto shop ...the students can work on it for credit...and for a grade, if your local collage has this course. :The function of the engine's cooling system is to remove excess heat from the engine, to keep the engine operating at the most efficient temperature, and to allow the engine to reach its ideal operation temperature in the shortest time possible. In an ideal world, the cooling system keeps the engine running at its most efficient temperature no matter what the operating conditions are.
The cooling system of a water-cooled engine consists of:
The engine's water jacket
thermostat
water pump
radiator and radiator cap
cooling fan (electric or belt-driven)
hoses
heater core
expansion (overflow) tank
Broken tubing. Hoses and tubing wear out and leak coolant fluid. Once the coolant has left the system it can no longer cool the engine and therefore the engine will over heat.
Broken fan belt. The water pump is driven by the engine through a fan belt. If this belt breaks the water pump can not turn and coolant will not be pushed through the car engine. This will also lead to the engine overheating.
Damaged radiator cap. The radiator cap is designed to hold a certain pressure in the coolant system. Most caps hold 8 - 12 PSI. This pressure raises the point in which the coolant will boil and maintains a good, stable system. If your cap does not hold enough pressure, then the car engine could overheat on hot days since the system never becomes pressurised.
Water pump failure. Most commonly you will hear a horrible screeching noise and will be able to see engine coolant leaking from the front of the pump or underneath the car. Often there are early signs of trouble with small spots of coolant under the car after being parked overnight and a strong coolant odor whilst you are driving.
Head gasket... Do you have large amounts of white smoke flowing out of your exhaust? Then you could have a problem with your head gasket. The head gasket seals the cylinder head to the engine block and also seals the coolant passages. When this gasket fails coolant can enter the cylinder and it will be turned to vapor as the engine fires. Head gaskets most often fail after the engine has overheated in the past. When very hot, the cylinder head can warp and prevent the engine head gasket from sealing properly.

If that jeep is more than eight years old, the radiator is probably partially clogged and ready to go at any time.
One other thing is, if someone has worked on it, make sure they didn't leave the spring out of the big hose on the bottom of the radiator. When you're going high speed the suction from the water pump will collapse that hose without the spring in it.

you should probably check the coolant. and your oil. but until you take it in to get looked at, you can keep the temperature of the engine down by keeping the heater turned up. it helps out a lot. i had a car that over heated all the time....and then antifreez would leak all over the place....but since i coudnlt afford to take it to a shop, i left the heater on all the time and it stopped overheating.

Your cooling system may be partially blocked thus making it unable to supply enough coolant at higher speeds. Have your cooling system back flushed. Also check for anyleaks to hoses and radiator.

Sounds like a coolant restriction somewhere. Most probably the radiator.

sounds more like a radiator getting stopped up

Could be a sticky thermostat.
