You need to replace the thermostat and flush the system of crud.
I’m not sure, but it stands to reason if they take a 3 core off they should put a 3 core back on…
Hi have you checked the radiator for blockage if it is blowing water back out the radiator this could be the problem.
It could be one of several issues: 1. The sensor in the radiator overflow bottle is stuck, disconnected or damaged 2. The actual level of fluid in the radiator itself is low, perhaps caused by a blockage or interruption in the overflow tube that connects the radiator and the overflow bottle 3. The thermostat is stuck in the open or closed position, requiring a replacement of the thermostat First things to check: 1. While the vehicle engine is COLD, check that the level of fluid in the reservoir does not exceed the COLD level. 2. Run the vehicle for 20 to 30 minutes of normal driving, then check the reservoir level. The level of fluid in the reservoir should be raised to the HOT level. 3. Let the engine completely cool for several hours. Check the reservoir level again. It should have dropped back down to the COLD level. If the level in the reservoir does not change between the times the engine is cold and hot, you have a problem with your engine's cooling system. Wait several for the engine to completely cool, then open the radiator cap and verify that the radiator is full of fluid. Check the overflow tube that runs from the radiator neck to the reservoir bottle to ensure that it is free of obstructions.
May be the neutral safety switch. Mine was dirty and I was having issues getting it to start.
I am having the same problem, plus have had sensor issues too
A radiator cap would not cause a leak! However, if the radiator cap is holding pressure, other weak parts could signal issues in need of attention.
I'd assume that the coolant hasn't been changed in a while. Take it to a garage or if you have the tools do it yourself. If you are not having cooling issues in hot weather, then just drain and replace the coolant included the plastic expansion tank. If there are any cooling issues or leaks, then take it to a garage and ask them to test. The radiator may be clogged inside preventing a free flow of coolant. They will either flush the system or replace the radiator.

One might consider the best Cherokee car to be the newest model of Grand Cherokee. The 2011 model has addressed a lot of the issues that previous Grand Cherokee owners had with the car. Speak to Cherokee owners you may know or head to a dealership to test drive a car before making a final decision.
The heater core could be bad. Or, as was my case, you may have issues with your radiator. If the radiator is cracked and is not able to generate enough pressure the heating system will not function.
The ARC doesn't have a union; there are no union issues.
