You have a front wheel drive car so it requires and electric fan motor which in turn requires a temp sensor to tell it to turn on. The sensor should be on the radiator itself. Check that the connector to the senor and the motor are tight and if the wiring checks ok then I'd go for the sensor first.
The reason it cools while driving is the natural flow of air at driving speed.

SOURCE: engine overheating there is no coolant leak but it overheats and

1st it is imperative that that cooloant mixture is correct. once you have the correct mixture have the thermostat replaced. Or just have a mechanic replace the thermostst and they will balance the coolant to water mixrure

It's possible you have a blown head gasket. In that case, the heater core which is above the engine fills with exhaust and stops working. To verify this condition, check exhaust for excessive white smoke. If leak is still small, it's possible you won't see much. In that case have a shop check the radiator for hydrocarbons (exhaust). If the test shows any in cooling system, you definitely have a head gasket problem.
I'd also check the thermostat. Sometimes it can give similar symptom but more often than not this will trace back to the hg.

Car started knocking really bad got a cylinder 2 misfire code after opening coolant bleed valve with enging hot


Okay, it may be due to overheating, that may be the noise you heard, lets hope. first allow engine to cool, open radiator cap or the resivoir cap, which ever is the fill, remove the bleeder at top hose and fill radiator slowly until coolant comes out bleeder.

note if water pump was replaced due to leaking and engine was overheated at that time then it may be a good idea to replace the thermostat .
after filling is done start engine and allow it to run. watch temperature if temp start to climb past half way shut engine down and let sit for 5min. then restart and check level, in res do not open cap . feel air from fan and see if it is getting hot, this may take up to a half hour but do not drive,

A few questions, does this jeep have an electric fan?
when you heard the knocking was engine temp hot?
If you start jeep cold does engine knock?
Did this jeep get a new thermostat with waterpump job?
did it overheat when pump went bad and why did water pump get replaced?

sorry for all the questions ,just trying to get all the info to help you .

first check coolant level in radiator coolant level sound low.if coolant overflow jug empty.coolant sysyem low, when add coolant to coolant overflow jug coolant level should stay at full cold mark.if coolant level okay,engine overheat while sitting or moving in slow traffic either coolant fan relay or fuse could be bad.or engine coolant temperature sensor could be bad. coolant sensor turn on cooling fan at certain temperature.hot wire check to make sure cooling fan motor not bad or short in wires.if all is good have pcm check it controls fan relay to through the coolant temperature sensor signal when coolant get hot.

Will a leak cause the radiator fan relay curcuit to malfunction on a 2003 jeep liberty 3.7


a leak in coolant system will cause air pocket in the coolant system around the engine coolant temperature sensor.coolant sensor is a thermistor in which when hot cool cause it resistance decrease which affect the voltage from sensor to pcm which will cause engine coolant to turn on.if coolant level okay,check coolant fan fuse and relay, if all is good,engine coolant temperature sensor could be bad or have vechicle code scan for pcm problems it control the coolant fan.fill coolant system to correct level make sure engine coolat reservoir is at full cold mark and not empty.fill coolant system check for leaks,refill coolant overflow jug back to full cold mark dont over fill, if coolant overflow stay empty you have leak either its leaking or you have radiator hoses or radiator leaking coolant.when coolant overflow jug run dry it cause air get in coolant system causing overheating problems.

My antifreeze is leaking and its freezin cold?


first find the leak and repair it. second, make sure it does not overheat again or you may also need a thermostat. Your heater will not work when coolant level drops below a certain level. since it's leaking, likely that level has been reached. After repair has been made, re-fill with 50/50 antifreeze mix, with the engine running and heater on full heat to allow air in system to escape. If while filling it begins to overheat and keeps spitting out coolant, replace the thermostat.

My 2000 jeep grand cherokee is overheating when i drive less than one mile and the coolant light is going off. i replaced the thermostat and checked the coolant level (which is fine) but it is still...


replace your cooling fan motor relay because if you dont eventually your radiator will explode and this will cause your engine block to crack and then if your fan isn't blowing the engine will continue to overheat and the engine will seize and then you need a new engine. A cooling fan motor relay is around $30.

Overheating, don't know why


The most common problem with overheating is the thermostat. It becomes plugged and won't allow enough coolant to pass through the system. Another cause could be old coolant. Flushing the coolant periodically (when the coolant appears to have rust in it or has faded in color) is a good idea to keep the antifreeze/coolant up to peak levels. Bost are worth looking into but I'd be surprised (barring any leaks in the sytem) if the thermostat wasn't the culprit here. Best of luck.

When jeep overheats quickly, it dumps water and coolant


When water gets hot it expands that is why you have the overflow box. If you are overheating check the water pump and thermostat
