NO,THERES NO FANS MISSING.YOU SHOULD HAVE EITHER AN ELECTRIC OR THERMAL FAN FOR THE RADIATOR AND AN ELECTRIC FAN FOR THE AC.

I turned my ac in an took a 30 mile trip n back. My vehicle started overheating n now it keeps overheating. Wat could be wrong with it?


Sounds like the electric cooling fans are not engaging. There is a sensor that is usually found on the side tank of the vehicle that senses coolant temperature. When this sensor goes bad it does not start the electric cooling fans and then the vehicle overheats from the extra heat produced from the AC system and increased engine load. It is not the thermostat or it would overheat quickly upon startup in about 10 minutes. Check the electric fans. Should be two of them.

Engine Cooling problem 2000 Jeep Cherokee 4 cyl


Although the 4 cylinder is too underpowered to have air conditioning in my opinion, it still shouldn't overheat within 10 minutes unless something is wrong. If your Jeep doesn' not overheat when you are driving WITHOUT AC on then your compressor might have a problem and causing the engine to work too hard to turn it.

But if it overheats without the AC on, then the first thing you need to do is check the cooling fan and see if it operates! There has been a lot of problems with the cooling fan relay on this model. If that isn't it, then move to changing the thermostat and checking the water pump.

You probably have an electric radiator fan that isn't working properly. First thing to check would be fuses, then swap relays if no blown fuses are seen, and finally check at the fan connector for power. If everything is good, you need to replace the fan motor. It isn't very fun trying to figure out how to get the fan shroud/fan out. The 4 bolts holding it to the radiator are in the worst spots and it will prob take an hour or so to get the bolts out before you realize that it's super tight in there. Good luck

It overheats while idling


could be your thermostat is not opening or if you have an electric fan is not coming on. when you drive the wind is hitting your radiator and cooling it off thats why it is only running hot when you stop

Be certain that your electric cooling fan is coming on. I have the same issue right now. It actually got so hot the first time we noticed there was a problem that it cracked my radiator. Replaced with one from Autozone for $150. Dealer wanted $350. I ordered a cooling fan on ebay that should come in today for $70.

Engine overheating


Try to flush the system And inspect radiator. When moving the engine is also cooled by air. Make sure the water is circulating trough the manifold and the heater core. You can do this by atching a garden hose to each hose one at a time. You may also want to check the waterpump & thernostat..

2001 jeep grand cherokee laredo overheats when vehicle sits idling. Cools down when i take off and drive down the road...??? Please help. thanks


Many cars have a thermoswitch threaded into the radiator that activates the fans when engine exceedes normal optimum opperating temp. This sensor may have failed , or one of the 2 wires that go to it may have come unpluged or broken
