    Have the cooling system checked for hydrocarbons...you may have a cylinder head or gasket problem.

When the radiator and/thermostat is replaced in a Jeep, the system needs to be "burped" of any air let into the system. Park the vehicle on ramps or an incline with the front end pointed up. Remove the radiator cap and run the engine. If there is air in the engine, bubbles will escape from the radiator cap (which is now the highest point). Watch the temp carefully while doing this for overheating. If it still overheats, my best inclination is that the thermostat itself was installed backwards and there is no flow. This is easy to do if not paying close attention, it will fit either way. Could also be a bad thermostat. If the burping doesn't work, install a new thermostat paying close attention to flow direction.

Overheated. Why won't it start?


I'm not really familiar with JEEP mechanics but if you've replaced your water pump and it's still overheating with full water/coolant level, you should check the thermostat; when it fails, it's a common cause or overheating in all kind of cars

I have a 2002 Jeep Grand Cherokee. It gets very very hot and then stops running. Can you please tell me why


Have you checked the coolant level in the radiator and coolant recovery tank? If low, add until full level is reached. Other causes could be a malfunctioning water pump, slipping serpentine belt, or stuck thermostat. Do you have a temperature gage or just a warning light? When this happens and you stop the engine for a few minutes, are you able to restart an d keep going? If so, I'd look at the thermostat as the problem.

Coolant isn't circulating in the engine of a Jeep 2002 Grand Cherokee V8. Radiator was just replaced as well as the water pump and thermostat.


Hi Jonny, While the engine is cold the thermostat will be closed, allowing coolant circulation around the engine block and cylinder head but not through the radiator. Only when the engine has reached normal operating temperature will circulation be noted in the radiator. A good test is to remove the thermostat while the engine is cold , start the engine with the radiator pressure cap removed and observe flow. If as I suspect it is there, refit the thermostat and check the heat gauge. If all remains well there is no problem. If the engine overheats replace another thermostat. If there is no circulation with the thermostat removed, there is a blockage in the cooling galleries of the engine. If chemical flushing does not clear it, it will require disassembly of the engine with careful step by step inspection at every stage. If the cylinder head(s) had been removed I would suggest making sure of the galleries not being blocked by installing the gaskets incorrectly. Regards John

Overheating issue


You need to get a pressure check on the cooling system. I suspect a bad head gasket. Engine compression leaking into a water passage would force coolant back out of the engine. Hope this helps.

Overheating while Eating


Bad themostat, dirty radiator (the front of it), corroded interior core of the radiator, weakening water pump, bad radiator fan.....just to name a few. More than likely? Low antifreeze level, or the thermostat.

If you put the thermostat in correctly (spring towards the engine) that should be OK. Likely if the water pump wasn't leaking or had a bad bearing, you wasted your $ on that.
If you re-filled it and did not have the heater on high heat, you may have some trapped air in there. But, still overheating says another thing. If you have a blown head gasket, it can pump compression into the cooling system and drive the coolant from the core. It will also overheat. You can have that tested at most any decent shop that will do a hydrocarbon test to find that.I think someone makes a chemical test kit for that but not sure if it's very expensive or not. White smoke from tailpipe will also be an indicator as will be any coolant in the engine oil or coolant on one or more spark plugs. If it turns out that it has a head gasket problem don't stop looking for problems as often a faulty fan or obstructed radiator can cause the initial overheat that caused the gasket to fail.

Intermittent overheating on 96 Jeep Grand Cherokee


Sounds like a sticky thermostat. Not unheared of even though fairly new. Just double check rad fan comes on at about the 220 mark, and not at 260 mark.

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