SOURCE: My 99 Jeep cherokee laredo keeps overheating

the reason it getting hot when stopped is the fan relay is out thus not turning the cooling fan on,this is a time consuming job,the relay is located on the passenger side tip of the frame behind the headlight,the grill,headlights,bumper,and tip of the front fender has to be loosened up to get to it.
The relay is about 70.00 or so,the engine cools down when you drive as you are forcing air through the radiator to cool it down,as for the heater issue probably caused by boiling the anti freeze out ,
To make sure the engine is ok do a compression check to verify the headgasket and heads are ok,as for smelling the sweet smell which is antifreeze probably due to overheating and pushing the fluid out of the cap or tank.

SOURCE: 2000 grand cherokee overheating heater blowing out cold air

Generally this condition is the result of coolant loss, or failed thermostat. If coolant goes below cylinder head level, or thermostat remains closed,heat will stop working. Do not drive with this condition as excessive heat buildup in cylinder head can and will do serious damage to heads and or head gasket.
Find out where leak is and correct it. Change thermostat as it may also be damaged. Check for excessive steam from tailpipe or miss in engine, as these symptoms indicate a cylinder head problem.

You need to remove all the skrews from the door. Normaly there is one in the handle of the door, one behind the in door lach handel and one under the bump out for the arm rest on the door. Than you need to take a flat head skrew driver slowly priying the panel off. There are plastic clips on the backside of the panel it is ok if you brake a few.

SOURCE: my jeep grand cherokee started overheating at idle

try the water pump - first - make sure the radiator is really full - take the cap off cold and fill - if it looks full - start and run 8 minutes or so - then fill it up - look at ur fan belt - is it tight - tight is about how much pressure u use to make a firm hand shake with little movement - any movement over about an inch is loose - when the jeep warms up the belt can slip and not even make a noise - - new materials don't always squeal. - then be sure ur water pump is ok - they go slowing - the fins wear down - one more thing is the radiator - u don't say how many miles or what maintenance schedules you have or not so that's it for now

Check hoses going to heater core. Do both get hot? If so, problem may be a "blend" door failing to actuate due to vacuum leaks or bad actuator. If neither get hot, change thermostat.

If the fan is not cycling when the engine gets hot, you'll have to test the fan motor and the temperature sensor. If the fan is running and it's still hot, the thermostat may be the cause.

The heater is my Jeep is not blowing very warm air. It puts out mild heat at best. I have a 2001 Jeep Grand Cherokee Laredo.


I would recommend flushing the cooling system and replacing the thermostat.....easy to do and only about $14 for a new thermostat.If that does not work then you either have a coolant leak somewhere or a bad heater core. I would also pressure test your cooling system before you flush the system to look for leaks in the system

Heater wont work its as if the heater core is not getting fluid


Sounds to me like the thermostat is stuck open on the vehicle. Replacing that should solve your problem.

Overheating issues for a 2001 grand jeep cherokke


If it was overheating at freeway speed then it is a clogged radiator. Another cause of overheating is a timing that is retarded. These can be caused by worn timing components etc, although a possiblity it is highly unlikely on your car.
