Could be a several things, start with the easiest first,

1. Thermostat (DIY for under $10.00)
2. Radiator Fan relay (DIY for under $50.00)
3. Water Pump (DIY for under $70.00)
4. Bad fan motor

Does your radiator fan run when AC is on or when engine is above 200F?

2000 jeep grand Cherokee stalls while drive or idling no codes


which engine? 2000 GC, is a body, stalling is and engine issues.

there are 5 reasons (physics) to stall, and 50 ways. (reality,say head valve stick hot only??? and lots more.)

ill not list them (searching shows my posts doings so 100 times)
but will ask you one questions.
can you save the stall with a fast right foot.??????????
ok 2 .
does the dash lamps (any ) go dead at stall point.?

the scan tool only works best , scanning and driving and for sure
at the stall point, so?
for example misfire codes clear in 1 second if gone.
so you missed that...... real time scanning is best, others like trips
to autozoned are near useless. IMO. why work, blind, ?

for better answers join a real jeep forum (google that)
this forum fxxxa , sux at this, it has NO structure here, nor abilities
to see your car, your engine, and others with issues related.

When idling my jeep overheats. The cooling fan is running and it speeds up when temperature goes up. The temperature gets close to 260 degrees and the engine tries to stall. when I start moving it cools...


At idling speed an engine does build up a lot of heat and the cooling fan will kick in. In slow moving traffic or traffic jams the temperature gauge can touch the red - particularly on hot days. The reason it cools down when you start moving is because of the air flow through the radiator.

Presumably there are no leaks from the cooling system otherwise you would have mentioned it. In normal circumstances the fan will not be running as you are driving at speed, as the air-flow through the radiator is sufficient to cool things. The fan only kicks in to get rid of excess heat - and this usually occurs at idling speed or after you have parked the car.

If the fan is running all the time as you drive, this points to either a fault in the fan switch, or the car is running too hot. presumably in normal driving the fan isn't running and the temperature gauge reads normal?

It is common - in stationary traffic many cars overheat (particularly big engined models) try to stall and 'cut out'. Restarting can be difficult until the engine cools down.

Is your car overheating in normal driving conditions or just at idle speed? Overheating in normal driving conditions can be caused by things like a failing water pump, blocked radiator, collapsed hose, faulty thermostat or, in the worst case scenario, cylinder head problems.

Overheating at idling speed is 'common'. Check your coolant level. If your car isn't using/losing coolant then there probably is no major problem. You can flush out the cooling system and refill with new coolant - and also check your radiator. Are the cooling fins crumbling with age? Or maybe they're partly clogged with insects and debris from the road? A blast with a hosepipe wil sort that out ..

The question is how much does your car overheat in normal driving? If it doesn't .. it appears as though you have nothing to worry about as such. Most cars have 2 speed fans... the 2nd faster stage kicks in at some point dependant on engine temperature. Perfectly normal.

Engine Overheats when AC is on..


It sounds like your AC compressor bearings may be overheating causing excessive drag/loading on the engine. No easy way to check this unless you can take the serpentine belt off when the car won't start and see if it is really hard to turn the compressor shaft.

Rough idle, stalling


You must get the system scanned for fault codes, sounds like the electronic throttle control has a failure.
