Stuck thermostat, leaky head gasket which the coolant goes into the motor and is burned so there's no leak on the outside. busted water pump. those are the other 3 things that can cause this. after you drive for a little bit, dose the temp go up then drop fast and slowly back up again? if so, it's the thermostat. dose the temp just keep rising and rising and not blowing warm air through the vents? then the water pump. Having to keep adding coolant and no visible leaks? head gasket more then likely.

The Jeep Liberty has had a few problems with overheating. I recently had the pleasure of dealing with may sister in law's vehicle that had the problem for over six months. After taking it tot he used car dealer where she bought it and them not doing much for her until the one month warranty expired, they finally told her that the car needs the cooling fan relay replaced. By then I had already troubleshot the problem but it is not that simple.

In order to get to the relay you have to remove the headlights and front bumper. The best thing to do is to get the replacement part from AutoZone. They have a kit that repositions the part to under the battery for the next time you have to replace it. The first time will take you a couple of hours to get it done, after that it shout take no more than five minutes. I say after that because, although there are a few aftermarket parts to replace this relay, none of them has gotten it right and the part will keep on braking. It is better for you to learn how to do it. If not you will be out anywhere from $350 to $600 every time it brakes. Simple repositioning of the part that cost about $60 and you are done.

Bottom line is. See if the dealer has a recall on this part and of not, put in a complaint to the service department for them to be aware of the faulty part on all of the vehicles. After that is done we may all get the right part installed and maybe a refund for all the money spent figuring out their mistake.

It can be faulty water pump or termostate. It might be no external leak but it might be leak into cabine through heater core or onto the engine and evaporate or coolant may go directrly into combustion chamber.
Check the exhaust if it is white in color, check the oil for coolant (milky in color), check coolant for oil. If you have any of these problems you have bad head gaskette
Good Luck

Why did this happen all of a sudden, Overheating (maybe) and RPM Sensor Pointing down?


If the noise was coming from the cooling system, first try to replace the radiator or expansion bottle pressure cap. The RPM needle probably is unrelate to the cooling system problem.

If your coolant overflow is bubbling then regardless of what your gauge says you are having overheating issues. If your coolant is missing with no aparent leaks then you need to check your oil for a milky consistency and apearance which would most likely point to a blown head gasket. This would also explain overheating. Hope this helps

How can i tell why oil gauge does not work?


This can be due to failure of the Gauge if the engine seems to run well witthout any overheating.
However if you notice there is severe heat or poor performance then there can be LOW OIL pressure and so this is a problem within the engine which needs to be checked in detail.

sounds like your coolant level dropped enough to empty the heater core and your engine was not getting coolant up to the cylinder head, check the coolant immediatly and fill then idle in the driveway till fully warm and you should notice the leak
