It could be the thermostat which is cheap and easy to replace. The mechanic should have replaced this along with the new radiator.

SOURCE: radiator fan for 2001 Jeep Cherokee

Had this problem and one thing that even Chilton manuals only show in fine print sorta say is that Jeep cherokee has a relay sensor for the coolant fan usualy right behind the passenger or driver side headlight you may have to remove the bumper also its rather easy.Its a liitle black box thats screwd down on the panel just unscrew it unplug it replace mine ran me around $60.00.Before I learned about this after replacing the thermostate and just about to rip out the water pump my buddy told me about the sensor after replacing over a year ago no problems.

SOURCE: 2001 Jeep Grand Cherokee Radiator Fan Doesn't run

Have you confirmed the fan has a good ground, sounds like you have eliminated the issue of 12 volts, when you turn on the fan then the AC does the compressor run? if the compressor runs pull the plug to the fan motor and check to see if has 12 volts with a test light, wait for moment because the fan may not run until the AC system pressure reaches a certain pressure point, this means that even though the compressor is running the fan may not always run, There is a quick test for the fan circuit, disconnect the fan sensor at the thermostat housing, the fan should come on, this is failure mode, so if the switch goes open the fan will run to keep the engine from overheating , let me know after the tests are run.

SOURCE: no heat when car not moving

Ok, judging from what you've said it sounds like a vacuum issue. The temperature controls are activated by vacuum which is produced by the engine. Look for small hoses that lead from the intake manifold to the firewall, check them and make sure they are not broken, disconnected, or leaking.  The vacuum directly controls the doors inside your dashboard which push the air to the heater core. Also make sure that the coolant hoses going to and from the firewall are hot.  If all that checks out, then the controls inside the car may have gone bad, or may have become disconnected from the vacuum supply, or the actuator door inside the dash is stuck or broken.

Yes you have to check your pressure with a mechanical gauge first. If the pressure reading is good replace the oil pressure sending unit. They are known to go bad, and oil pumps going bad is rare.

SOURCE: My 2000 Jeep Grand Cherokee overheats in traffic

Check the fuse for the fan and use a test light to make sure that the circuit is functioning. Warm up your car then feel along the top and bottom of the radiator to check for cold spots. If you find any then you may need to replace your radiator. If your heater isn't currently working it may be that since it is a part of your cooling system.

Temp. guage indicates overheat 10 mins. from startup


Hi Reggie, I'm glad to help. TWO things I want you to check. ONE: You have changed out a lot of stuff, so you may have air trapped in the cooling system, you'll need to remove the radiator cap and let it run until your at operating temperture, while watching to make sure it doesn't overheat on your of-course. If after running the engine say 30 minutes and topping off the coolant if needed, it still runs hot. Move on to: TWO: If you have the electric fan, some do, some don't. If it is electric make sure the fan is coming on, if it doesn't come on then you have found your problem, replace the fan assembly. Hope this helps and have an awesome day Reggie!

If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

Engine fan not working


Could be low on coolant, the cooling fan motor, a relay, or the fuse among other things.
A mechanic would check for power at the fan motor after checking the fuse.
Is the check engine light on ?

Guys, I have Toyota Revo 2001 manual diesel. Its getting overheat only during idling or heavy traffic. We overhauled the radiator, new radiator cap and hoses, new thermostat, the fan is ok. the pump is quiet (no noise). Still, its getting overheat. please help me guys! Thanks!

Both heads have been replace, radiator checked out thouroughly and car still overheats when used in traffic on a warm day. could it be related to the airconditioner being on . The mechanic idles it for a...


Over heating is relative to the wrong timing or the poor setting on an engine if there is no issues with the radiator , the radiator sealed unit. pressure cap, the water jackets in the main block and the water pump.
It is important to have the timings checked on the ignition system. If the radiator is blocked the engine can overheat specially when the engine idles with the a/c On.

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.

It really does overheat a lot when in traffic.


You need to check youe water pump, thermostat and your radiator cap and if all of that is good it sounds like a blown headgasket.

My scerity sys went off and I my car over heats I think it needs a new thermastat


maybe your security system monitors engine temp ... it doesnt have to be the thermastat thats bad .. it could be the radiator fan switch or relay bad .. you can tell which by the following.
1. if it overheats only when idling or in heavy traffic but does not overheat while on the road (moving) then your problem is more likely the radiator fan switch, relay or fan motor ..
2. if your car overheats all the time even while driving then it could be the thermostat ..

check belts, coolent level and radiator clogging ..

Overheating


  1. There are many different reasons that can cause an engine overheat, but they all have in common three aspects. The three aspects which all engine overheat factors have in common are that they cause that the heating system can not get rid of heat, they cause a loss of coolant or they directly cause too much heat in the engine.
  2. One first problem which might be the cause of an engine overheat is a problem with the radiator cap and the pressure it holds. If the radiator cap does not hold pressure correctly then coolant could boil and therefore the engine would overheat. Another reason might be caused by thermostat failures; it is recommendable that you check it.
  3. The car engine might also overheat due to coolant leaks such as those from the radiator, the hoses, the water pump, the freeze plugs or any others. Also, problems in the water pump could be the cause and therefore you should check it and replace it in case it is needed.
  4. Some other reasons by which the car engine could overheat are problems in the exhaust system which you can discover by checking vacuum readings, pipes and converter. Besides, you should also make sure that the radiator hose has not collapsed and the ignition timing is working properly.
  5. You should also check the electric cooling fan by making sure that the fan motor, the relay and temperature are correct or otherwise it could cause the engine to overheat. Besides this, you should also check the radiator in case there are any debris in it as well as you should check its hose in case it has collapsed.
  6. It is also recommendable that you check the antifreeze concentration which should be 50/50 in order to be correct, otherwise it could cause the car engine to overheat. If you do not find why your engine does overheat, you should ask a mechanic or an expert for advice. You should not try to fix this if you do not have the proper tools and general car knowledge necessary for it.
