Here is a real tricky one

Check your radiator hoses. With age I have seen them collapse on the inside of the hose (look good on outside)causing reduced coolant flow and over heating. Also check radiator cap. If not sealing properly or wrong psi it can cause overheating issues. Also what color is the coolant? Could the previous owner have added some fix in a can(stop leak) to it for some reason? If so you could be having a coolant flow issue due to this.

I am also seeing where a lot of owners with the 4.7L engine are having head gasket issues. Keep an Eye on your oil color and level. If oil level starts rising or it starts to look like a milkshake color you have a head gasket issue.

I am having the same issue, it overheats sometimes. I replaced the fan, then figured out that it wasn't the fan. I know it isn't the fuse, and likely not the thermostat, but however I am cleaning the relay right now to see if it will help. I called the dealership, and they said it is a common problem with jeeps ,and it is likely either the relay or wire harness

I don't know if you're still having this issue, but check your passenger floorboard. If there is coolant there, your heater core is bad. I had the same problem and eventually the coolant started leaking into the floor. Hope this helps.

For a 3.7 it was the radiator. Replaced it. Fixed. BOOM.

I have the same problem with 2005 jeep grand Cherokee Rocky Mountain 3.7. I got the engine light i checked it and they say it is the O2 sensor for in the right so i changed it but still i have the same problem. It do control the temperature and other things. What will happen next is i will get all sensors checked in the jeep so i can know which one is making the problem. I don't know if this is the right thing to do?

Rocker arm has fallen off on #8 exhaust valve I can guarantee it !

i have an 05 jeep grand cherokee laredo and i recently discovered the heat not working. i bought the vehicle back in march in california i did not need the heat up until recently and the heater wasnt working. i put it on blast and tried to use the defroster as well and that wasnt working then i started smelling antifreeze smell maybe like burning plastic or melting plastic and a few days later noticed wisps of smoke coming in to the cabin from the vents my jeep started getting hot when it was sitting in traffic. im taking it in to get diagnosed hopefully its an easy fix ive never had any problems with it for almost a year and now its acting up in the winter which is odd. because it was a hot summer and it never overheated and i commute thru the bay area a lot and i never had issues.

Chances are your heater core is leaking if you have smoke-like wisps coming into the cabin. Check fo moisture on your passenger side floor mat.

If you didint find the right thing for the Jeep change

Water pump in water cap

It happened to me to in i change the water pump and the cap

Might I suggest you check your fan clutch...if free wheeling..it won't move air through.the radiator if idling in traffic or at low speed..Ac on makes it worse...highway speeds would be enough to cool

I bought a 2005 Jeep Grand Cherokee and it was running good the check engine light was on I had it checked and it was saying I needed the core packs changed I did that along with the spark plugs. The jeep shuts off while I'm driving only when the temperature outside is high in the winter it's fine no problem the gauges doesn't show that it's overheating though.My air stopped working but someone put a wire to the compressor and it blew cold I'm not sure what's that about but I told them not to leave it on there so it would mess anything else up. Any suggestions?

Check coolant temperature sensor.

I have a 01 Jeep 4.7 I had a collapseing hose so I changed radiator cap and that improved. Then I started getting coolent leaks from the hose so I changed the clamps. Then I started getting leaks from the water pump seal I tightened the bolts and it improved. But I still have a outside leak. Wtf is going on ? Bad radiator cap ???

I have this same problem ...rocker arm fell out of # 8..put a new one in and I think it happened again..also seem to have big leak from radiator ..mutliple problems or all linked ??

I got an even better one for you I have a 1993 Jeep Cherokee 4.0 Inline 6, The temperature gauge is going up and the block is getting hot but the radiator, radiator cap, thermostat, and water pump do not get hot at all? Why is this doing that cause I know quite a bit about Jeep Cherokees and I have never ran into this problem before. I just replaced the pump and thermostat and it was working great now all of a sudden bam just starts doing this. I have been told there could have been some kind of stop leak in it and now it's clogging something up but if that's so then why is the radiator and all getting hot as well... I am truly stumped on this one???!!!!

If anyone can help me please text me my number is 423-505-4295

Chad not sure if yours will have it but I was having a similar issue temp gauge would go through the roof and would get transmission temp high warnings and what not found out that my temp control sensor had gone out replaced that for about $20 and that fixed the problem up until recently now I’m thinking I’ll need to do a complete system flush and refill.

Hi well I have a 2014 jeep Cherokee limited today I took it to a regular oil change, well everything was ok I make a stop to fill up the gas tank and right when I try to turn it on it won't start it took me a while and a lot a difficulty engine light come on after that happened as well a really bad drain smell, honestly I don't know anything about cars and unfortunately my warranty is expired already, someone can help please. Thanks B

I have a 1997 Jeep and it’s to switch over to HEAT I GOT A AC CONTROL PANEL BUT ITS STILL NOT SWITCH OVER TO HEAT DO ANYONE KNOW WHAT IT COULD BE

Max answered 9 months ago I have a 01 Jeep 4.7 I had a collapseing hose so I changed radiator cap and that improved. Then I started getting coolent leaks from the hose so I changed the clamps.

On this one _ try this if not already fixed. I have an 02 Grand Cherokee that was somewhat overheating - Hoses collapsing when cooled off & losing some fluid everytime driven, After water pump, new hoses, new radiator & all _ It turned out to be overflow tank. There was a small congealed plug of antifreeze in bottom of tank that moved out when warm & let fluid in tank. When cooling off it moved back to plug outbound hole & caused blockage & slowly drained fluid from radiator & caused problem. Took 140 lb. air pressure to dislodge it after it had heated- cooled & blocked passageway. Would have been easier to replace Overflow tank. No more overheating & collapsing hoses. Maybe this helps. Good Luck.

Once the plug was dislodged & removed, everything worked fine.

im having similar problems the gauge will show hot and engine light comes on it doesnt overheat or smoke but ac is blowing hot air

Water pump

I have a 2005 Jeep Cherokee we changed out the ac compressor and now the motor seems to be shaking a bit I don’t know what to think

My Ford F-250 loses power going up hill??

? Does the overflow have any cracks in it or is miss the cap that will cause it to over heat on most Jeep s

I have an 04 jeep grand cherokee that would overheat and AC hardly worked.one day at walmart it was idling and the radiator hose came off and squirted hot water everywhere and was smoking
