Question about 2000 Jeep Grand Cherokee

2 Answers

Overheating I have replaced the radiator, the cooling temp sensor my fan runs, I don't think it cools enough because if I sit and idle very long or if I run the ac and its very warm out the temp. guage starts going up. I was sitting idling a few weeks ago and antifreeze went every where. no hoses broke or anything. The top to the overflo cap had popped open from pressure I believe.

There was a recall on this year Jeep GC. My limited 4.7L had to have the fan clutch replaced, but this was what the recall was for. Make sure that you check with your dealer to ensure your Jeep was included in the recall. Be careful where you take it as the dealer that replaced my fan clutch broke my rasdiator and I had to have the entire radiator replaced about 2 weeks after they did the work and they wouldn't cover any of it.

First of all make sure there are no air pockets in motor.
Run vehicle with radiator funnel or if don't have one run with cap off until top hose is hot.
If top hose isn't hot then the thermostat is not opening, need to replace. and repeat bleeding procedure.
If it overheats it builds up pressure and causes overflow cap to relieve pressure.

WORST CASE SCENERIO:
water pump is bad not allowing enough flow through out the vehicle.

Why is our 2010 cobalt still overheating after changing the thermostat?it has the 2.2 engine.the temp reaches 210 +degrees.sitting idled and the cooling fan is not turning on.The cooling fan only runs


was the thermostat installed the correct way round . Fans should start spinning at around 75degres c. Check coolant temperature sensor ( not temp. gauge sender unit) for operation. Have a flow test done on the radiator to check for blocked cores.. Have a compression test done to check gasket and for cracks.

Sounds like your cooling fans on the radiator are not working. The fans are activated by a thermol switch on the engine or radiator reading the coolant temperature and an A/C switch. When the coolant is too hot the fans should activate cooling the system down. And, when the A/C is on the fans should also activate in order to cool the condensate so the A/C would work.

When you are driving, the movement of the vehicle throught he air is providing enough air flow to keep things cool and functional.

I would check the radiator fan fuse or fuses first. If those are OK I would try to run the fans with 12 volts and a ground that I supply just to see if the fan motor(s) actually run when powered. If the fan don't run when powered then the fans are bad and will need to be replaced. If the fans do run when you power them manually, then something is not allowing the power to activate, like a relay, control unit, or wiring.

It will take a little diagnostics, but it is not too difficult to chase it down.

i would check and make sure the cooling fan is operating,if not it will overheat sitting still.a thermostat will cause overheating whether or not it sits still or driving(more so when driving).the same if it has a bad water pump although it may circulate just enough coolant when driving to not overheat with air flow also adding a cooling effect.if you don`t have a leak then i would say the water pump is okay as they usually will leak before causing a overheat problem.make sure the cooling fan is working and the rad does not have anything stopping the air flow over the rad and is not stopping coolant flow in the rad.

Overheating


WHEN CAR STARTING OVERHEATING MAKE SURE COOLANT LEVEL DIDNT GET TOO LOW. IF NOT I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP IF OVERHEATING WHILE SITTING IDLING COOLING FAN NOT COMING ON.CHECK COOLING FAN FUSE AND RELAY IF ALL IS GOOD.CHECK COOLING BY HOTWIRING IT.IF RUNS YOU HAVE A BAD COOLANT TEMPERATURE SENSOR OR FAULT IN WIRE CIRCUIT.IF FAN DONT RUN WHEN HOTWIRED REPLACE FAN MOTOR.IF CAR STILL KEEP OVERHEATING CHECK ENGINE OIL LOOKS LIKE MILK BLOWN HEAD GASKET.IF OIL LOOKS OKAY YOU NEED RADIATOR AND ENGINE FLUSHED OUT.

My 2000 Saturn SL2 is overheating. At first it would overheat when sitting idle and then once speed reached 35+mph it would cool off, but now it gets hot and stays. What is causing this?


Well, the overheating at an idle would normally be caused by your cooling fan not engaging. I would first check to see if you fan is working by turning on your a/c (this will override the fan sensor and turn it on before it gets above operating temperature). If it doesn't come on you should check your AUX. Fan Relay. If thats ok, you probably need a new fan motor but first replace your coolant temp. sensor as this is an inexpensive parts and may save you quite a bit of money (also your vehicle may be running at the normal temperature but your temp sensor may be sending a signal telling you it's hot). This will explain why it was overheating at an idle. As far as it overheating while driving, you should first check to see if your water pump is leaking and make sure your belt is intact. If the water pump pulley is not spinning your belt will be glossy from excessive heat from friction. If your water pump is good and you can spin the pulley by hand, you should then consider when the last time you replaced the thermostat as it may be stuck closed. also your radiator may have some blockages in it so I would replace the thermostat, drain the coolant by removing the lower hose and spray a hose into the radiator until the water comes out looking pretty clear. I hope this helps you figure this out.

198 mercury sable cooling fans motor


Cooling fans ( on radiator ) only come on when the engine reaches a certain (hot) temprature. There is a temp sensor threaded into the radiator end reservoir that switches a relay off and on that runs the fans. Either the temp sensor or the relay is probably bad. Normally , those fans will not be on if the car is moving , the air flow from just driving is sufficient to cool the rad. If you stopped and idled for a while , eventually the rad would heat up enough for the fans to come on.

I have 2003 grand cherokee with 140000 miles that overheats at idle. as soon as i start moving again, the temp goes back to normal.


You have two fan's on your truck, 1 is a fan clutch runs with the drive belt, 2 elec fan motor, with test light and engine running at normal temp, just a little bit above 1/2 way on your temp gauge check voltage at elec. cooling fan harness if you have voltage at one of the two wire's and fan don't turn on, bad cooling fan motor, on the fan clutch after you check voltage at elec. fan motor turn engine off, with your hand spin drive belt fan if it spin's freely bad fan clutch, replace it.Also check cooling level.Hope this was very helpful

Assuming engine tune / mechanical condition is not the cause of the overheating:-
Ensure cooling fan is cutting in at the appropriate engine temperature - check operation of the fan controlling relay,
Ensure fan switching control temperature sensor is serviceable,
Ensure cooling system is filled properly, taking care to bleed out air where necessary,
Ensure coolant pressure cap is of correct rating and in serviceable condition,
Check coolant hose on suction side of waterpump is not softened and collapsing at engine revs above idle,
Ensure radiator core is not blocked or cooling airflow inhibited by insects etc.

2003 Honda Civic runs hot when idling.


Check the cooling fan switch. It appears your auxiliary electric cooling fan isn't going on when at idle. and engine temp increases. While you are driving, air is being rammed thru your radiator as you cruise along, so it isn't overheating, at idle, that isn't happening, and the fan should go on as the temp goes up. When the ac is switched on, the fan is being signaled to operate due to the heavy ac load on the cooling system.
