Question about 2000 Jeep Grand Cherokee

2 Answers

OVERHEATING!! My 2000 Grand Cherokee is running hot. I have replaced the radiator cap, thermostat and water pump. There was a slow coolant leak which has ceased, but now the fan wont kick on, no matter how hot it gets. I understand there is a recall out there on the fan, but I have not investigated it yet. Any takers on what could be the problem? I could use the help.

If there is not power at the cooling fan motor, then a likely cause is the cooling fan transistor (Relay) which is located bhind the front bumper underneathe the right headlight. The bumper must be removed to reach it, but many people cut a hole below the removed headlight to gain access.

Sounds like you had a sticking thermostat when you replaced the waterpump causing an air pocket. Replace the thermostat, and jack the front of the car so that the radiator cap is highest part of the cooling system. Then run the car and burp the air out of the coolant system.

2000 daewoo leganza is overheating, leaking anti freeze, and water. what is wrong?


sound like thermostat sticking close.replace thermostat and radiator pressure cap.if already done.you could have faulty water pump.if engine overheating at long slow traffic line or setting at a stand still.the engine cooling fans should be running, check and see if cooling fans running if not,check cooling fans fuses and relays.if all is good,hot wire make sure coolings fans okay.if all is good,code scan vechicle for faulty engine coolant temperature sensor and ecm problems.you need a code scanner where you can check live data check see if coolant temperature sensor reading correctly if engine coolant temperature is 190 degrees the coolant sensor. the scanner suppose to show 190 degrees in temperature if not it reads 80 or 90 degrees the engine coolant temperature sensor is faulty need replacing.if all is good check engine oil if look like milk shake blow head gasket will cause over heating.to be on the safe side i would replace thermostat and radiator pressure cap first.to make sure engine coolant circulating through radiator and engine block.

Its keeps overheating i change radiator and head gasket and still overheating


Did you also replace your thermostat? If it's stuck closed, engine will overheat.
When you did the HG, did you have head checked for cracks or warpage? A cracked head will cause severe overheating.A warped head may or may not show signs of external coolant leakage. Either of these conditions can occur if overheating is severe enough.
Are your hoses in good shape? An old hose can collapse when it's hot, and restrict flow. Feel them (when cool) for any sign of sponginess.
New radiator cap? The cap provides a seal to pressurize the cooling system.
Finally, how about your water pump? Any sign at the weep-hole of leaking coolant? Your water pump inner seal is bad, remedy is a new water pump. Or maybe the pumps' fins have corroded and not pushing coolant sufficiently. If there is corrosion, get the whole system flushed and start anew.
Pull your spark plugs and look for any sign of coolant in the cylinders. I know it's a pain to keep going back and checking, but you gotta be thorough. Plugs may be blistered white from overheating, but if you get it fixed, they should be alright.
Now, finally, really: sometimes, Randy, just a small air pocket in coolant can cause overheating. So, make sure you bleed the system if it has a bleed screw, or fill, cap loose, run engine till t-stat opens, level in radiator drops, then re-fill, and add coolant to your overflow reservoir to around the full hot mark. Tighten cap, and you are done. Good luck.

2000 Jeep Grand Cherokee Leredo is overheating I changed thermostat also my fan is not working and keeps saying coolnd low and its full and the heat in the car will not run hot it stays cold


Sounds like some type of blockage in the system.
with the car cool open the radiator cap, start the engine to see if the coolant has flow.
Even though you just put in a new thermostat it can still be bad,I've had this happen to me a few times.
If the flow seems slow to nill you can also try removing the thermostat all together and giving that a try.
You can test the thermostat in a boiling pot of water.
If ir is totally not the thermostat then there could be a few cooling chambers blocked in the radiator.
This can be repaired in most cases by a "Rod out" at a local radiator shop.
I think the problem is more twards the thermostat for the reason you stated about your heater.
good luck,Gary.

I'm dealing with a 2005 Jeep Grand Cherokee with 3.7 litre V6. I just replaced a leaking radiator and thermostat and the car still runs hot. The fan is working and I see no leaks. What's next? Tell...


The rise in engine temp after replacing the radiator and thermostat could possibly be caused by air pockets trapped in the cooling system. You will need to run the engine with the radiator cap off and let the air escape. DO THIS only when the engine is cold, and let it build up to temp. Coolant will over flow during this process, but eventually coolant will need to be added once the air is released.

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.

Engine overheating


The best way to flush it would be to take off the bottom radiator hose and pump water through the fill nozzle after all the coolent is out you can then hook the hose back up and replace it with new coolant.
