2006 jeep grand Cherokee limited if the radiator overflow jug is empty will it cause the transmission temp light to come on


I would say it is possible an overheated engine which is not coolling the transmission can trigger a lot of lights. Many transmissons are heated and coolled by a line which goes to the radiator of the engine cooling system.

I have a 2000 Jeep Grand Cherokee that leaks fluid under the car. Took it to Sport Durst. Told them about the leak and that it sounds like water flowing through the dashboard. My low coolant light was


Put a large piece of light paper under the cars or truck motor area and let it set overnight. In the morning see what color the fluid is. Put your finger in the fluid that has leaked if any is there and see if it feels like water or oil. Coolant could be orange or green depending on the type you use. Coolant can sometimes be confused with transmission fluid. Check the water hoses that go into the dashboard for leaks. Also check for dampness on the passenger side of the front seat on the carpet area. If it is wet it is your heater coil that has a leak. Hope this hopes.

My dad put a new thermostat in my 2001 Jeep Grand Cherokee and it is now telling me my coolant is low and it is not. I just need to know how to reset this.


your low level sensor may be stuck sometimes a light tap on the sensor will repair the issue,make sure your coolant level is ok in the radiator and the overflow tank

My 2001 Jeep Cherokee is overheating after flushing the radiator and changing the thermostat. It is blowing cold air


Did you make sure you filled the radiator up and got the overflow tank up to the correct level? Sometimes when you flush and drain the system and fill it back up air pockets can get trapped in the system. Start the jeep up with the radiator cap off and wait for the coolant to start flowing and when the air pockets make their way through they will escape and you can add more antifreeze.

Also, did you make sure you installed the thermostat so it is facing the right direction?

Good Luck

2003 Grand Cherokee Overheating


This might help you as it looks as though you have an electric fan to cool , there should be a sensor on your radiator hoses upper and lower.they are actually switches triggered by the coolant temperature in side the hose. While your Jeep is sitting idle, shut off the AC as it adds to the heat off the engine not to merntion useing more gas. you should make sure both high and low speeds on the coolant fan work. good luck if this does'nt help check out the post, with more, on the 1995 Jeep heating up..

This means your thermostat is bad. Needs to be replaced. Also do coolant flush.

Radiator fan for 2001 Jeep Cherokee


Had this problem and one thing that even Chilton manuals only show in fine print sorta say is that Jeep cherokee has a relay sensor for the coolant fan usualy right behind the passenger or driver side headlight you may have to remove the bumper also its rather easy.Its a liitle black box thats screwd down on the panel just unscrew it unplug it replace mine ran me around $60.00.Before I learned about this after replacing the thermostate and just about to rip out the water pump my buddy told me about the sensor after replacing over a year ago no problems.
