SOURCE: 2005 Jeep Grand Cherokee Problem

I would start by checking all the fuses under the hood.
There is a fuse called IOD which the factory leaves out and gets put in at the dealer.
That fuse could be bad.

It's in the engine compartment IOD#2. It's a black module with two fuses in it. Take that module off and replace the 20 AMP one.

I agree, these vehicles have a problem with the blend doors and since the accuators hit the door when it opens and closes, it breaks the doors. and it's a huge job to replace them.

SOURCE: radiator fan not working replaced relay,temp

You didn’t mention replacing the temperature sensor located on the block in the path of the ‘cooled’ coolant.
I can’t tell you any closer where to look for it since you didn’t specify which engine you have.
This device is a solid state item called a thermistor.
With the air temperature around 77 degrees F and a 'cold' engine, it should measure about 10,000 Ohms and hot, around 1,200 Ohms while disconnected from its mating connector.
With the ignition on, and the connector disconnected from the sensor, you should measure about 5 volts coming from the ECU.
If this has failed, the ECU is not getting the right info back from the sensor and doesn’t know if the fan is needed or not.

I have a 2005 grand cherokee I just changed the waterpump now it runs hot and the information panel reads transmission over heating. What could the problem be?


Check the water level in the radiator as you may have had an air lock on initial fill and now the water level is below the top of the radiator cores. The transmission oil cooler is in the radiator and the box temp sensor will be reading hot because there is no water to cool the transmission oil

I'm dealing with a 2005 Jeep Grand Cherokee with 3.7 litre V6. I just replaced a leaking radiator and thermostat and the car still runs hot. The fan is working and I see no leaks. What's next? Tell...


The rise in engine temp after replacing the radiator and thermostat could possibly be caused by air pockets trapped in the cooling system. You will need to run the engine with the radiator cap off and let the air escape. DO THIS only when the engine is cold, and let it build up to temp. Coolant will over flow during this process, but eventually coolant will need to be added once the air is released.

My 2005 Jeep Grand Cherokee Laredo is running hot, should I believe it is the water pump? I still have heat.


Yes a bad water pump will definitely cause it to run hot. you'll probably be able to hear it as well as a whinning noise from the front of the engine. Also check for really low or incorrect fluid. jeeps are know for bad water pumps and leaky radiators. the heater pump is a seperate pump from the water pump. Also check for radiator fan opperation while the vehicle is stopped. If the fan is not coming on, it could be a fuse, relay, or intake air temp sensor.

2001 jeep Cherokee running hot


If you have the 4.0L six cylinder those run hot. 210-220 degrees. If the cooling system is fine, both fans are working and it's not overheating you can try adding a bottle of "Water Wetter" to the coolant. I also changed my radiator cap to an 18psi which seemed to help run slightly cooler. You find it at the autoparts store.

How to air my radiator to a Jeep Grand Cherokee 2001 3.1 engine ?


Try removing the radiator cap when the engine is cool and top off the coolant level. Start the engine with the cap of and let it run to operating temperature which is when the thermostat opens. If you lightly grab the upper radiator hose. If it is cool or warm, the thermostat has not opened. If it is hot, the thermostat has opened. At that time have someone assist you by sitting in the car to rev the engine up (1800 to 2000rpm) and hold it there while you once again top off the radiator and tighten the cap. DO NOT BRING THE RPM DOWN TO IDLE WITHOUT HAVING THE CAP ON TIGHT! THE HOT COOLANT WILL OVERFLOW FROM THE RADIATOR! Then let the engine run to see if the air has escaped. You may have to do this procedure more than once. If at any time you feel that the engine is getting too hot, tighten the radiator cap and then shut the engine off. Then let it sit and repeat the steps above. Constantly monitor your temperature gauge at all times.

Jeep Grand Cherokee running hot. I've changed the


Check your radiator for external and internal obstructions (leaves, bugs etc on the a/c condenser or leaves between the condenser and radiator, rust or calcium deposits inside the radiator core all cause loss of heat transfer)
Also make sure that the system is full and that the electric fan and the clutch fan are operating properly. (electric fan should come on just above normal operating temp and clutch fan should not be "freewheeling" above temp either)
Note: If you need to have the radiator flushed, do it separately from the engine. especially the inline 6 and 4 engines rust up inside and if the system is flushed with the radiator connected, the debris will pack up inside it and actually can worsen the condition.
