Your fan clutch is shot. Unit needs to be replaced. The original part had serious issues but has been upgraded. Make sure you get the newer type unit. When parked & cold, you should be able to easily turn the fan. If you cannot, the unit is bad.

If there is no noise when a/c is on and off, but there is noise when the fan is on, then I think it's the fan.

The fan on the radiator a/c should go on when first turning a/c on.

Hope this helps.

Good luck to you.

Over heats when idling but not when the air conditioning is on

Sounds like a bad relay to the cooling fan. When your air conditioner is on the engine fans run all the time, but when it's not it depends on a thermostat and relay for them to kick on at a certain temperature. I'd start the car with the hood open and the A/C off and see if the fans ever kick on.

Clutch fan?

no the fan that is used on most vechiles is called a viscus fan , it operates from the heat from your radiator, when you first take off the fan stays engauged because the liquid inside is cold and thick , causing a lock up in the fan, this is normal. once it gets heat from the radiator it thins and allows the fan to spin freely. then once enough heat is sensed by the coil windings on the front of the fan a valve inside is opened and the thinned oil is diverted and causes the fan to lock up again to help remove heat from radiator .

usually two types of clutches available,one engages with heat,the other is rpm controlled. The thermal clutch will stay quiet until the engine temp gets too high. Centrifical clutches seem to make more fan noise.

check on the engine around the thermostat housing for a fan control sensor. if your engine fan doesn't come on when the a/c is on, then thats your prob.

My jeep is heating up to about 235-240 after about 10 minutes of driving with A/C on. It usally takes about 30 minutes or more to heat up without the A/C on. I have replaced the fan clutch and thermostat...

Sounds like a partially obstructed radiator, either external, leaves between a/c condenser and radiator, or internal...some cores plugged ...radiators are actually too small for engine in the first place, making them what I consider marginal even when new. A good clue to an internal blockage is if the radiator cannot be filled quickly...a really bad one requires coolant to be literally dribbled in when filling, but likely yours isnt that bad yet. Everything else you mentioned seems normal

Fan kicking in too often 1998 f150 4x4 4.6 tow

If the engine is not over heating then it is doing its job. The constant cycling is based on the temp of the air traveling through the radiator and the a/c condenser not the outside temp so much. The start up high rev is just how these clutches work in ford fans. It sounds like it is operating correctly.

2002 Chevrolet Impala overheating while idling

the thermostates on the 3400 engines are late because the fans kick in at the last moment. if you run your ac on you will notice that the gauge stays in front of the half mark or right on the half mark. that is because when you turn on your ac your fans will kick in earlier and stay on the whole time the ac is on. if you run your car with the heat on or nothing on that leaves the late thermostate to kick in verus you turning on your ac and it by passes the thermostates and runs the fans once the engine gets at at lest 120 deg. i use to have a 2002 and i had the same problem. this will keep your engine cooler. also if you don't want your air on just turn on your windshield defrosters (not the back windshield) and that helps keep your engine cool because your defrosters use your air compressor which is really your ac. so it still kicks the fans on earlier.

Engine temperture runs hot after idling or waiting in traffic for an extended period of time perhaps 10 minutes

Sounds like your cooling fan may not be kicking on. Start the car in the driveway and just let it run with the hood open. When the engine starts to heat too much, the cooling fan should kick on. If it doesn't, it could be a fuse, a relay, a temperature switch, or the fan clutch itself.
