Jeep commander clutch fan?

no, it's more than likely your thermostat not opening and closing when it is supposed to....you could also have low coolant which i would check if you haven't already

I suspect that if you do not have electric fan/s then the fan clutch or viscous fan hub has failed
indications are over heating at idle , stop lights , slow traffic, high rpms at slow speed but cools down as soon as there is enough road speed to put air through the radiator.

does the temp gauge rise higher than normal ? the radiATOR COOLING FAN MAY NOT BE CUTTING IN . No heat at idle would also suggest the thermostat isn't opening correctly , so two things to check out

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 ?

Have the FAN CLUTCH checked. they are a common failure. Get a AC DELCO or the part from the dealer. Why was the radiator replaced? Heater work OK? A/C works OK?

Sounds like your cooling fan is not doing it's job while you're stopped. While you're driving, the air rushing past the radiator is cooling the engine. The fan is supposed to pull air through the radiator while you're stopped so it has to be defective. Have it looked at.

Hello and welcome, it sounds like you need to replace your fan clutch. Your Jeep has 2 cooling fans 1 runs off the engine the other is electric. Before replacing the fan clutch you need to make sure the electric cooling fan is working just turn on your a/c and it should kick on. If it does then the problem is your fan clutch is it doesn't then your electric fan is most likely bad.

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.

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

This might help you as it looks as though you have an electric fan to cool , there should be a sensor on your radiator hoses upper and lower.they are actually switches triggered by the coolant temperature in side the hose. While your Jeep is sitting idle, shut off the AC as it adds to the heat off the engine not to merntion useing more gas. you should make sure both high and low speeds on the coolant fan work. good luck if this does'nt help check out the post, with more, on the 1995 Jeep heating up..
