Yeah try to change the sensor.maybe it is busted. normally, most of the late-model cars comes with a fan feature that turns of after 5 or 10 mins even after switching off the engine. this helps to cool down first the engine to reach its desirable temperature before it is totally shut down. its good that your radiator fan has a feature like that. aftermarket perfomance fans do come with that feature because it takes care of the engine state.just try to change the sensor for engine temp

I have same problem with my A3 1.6AVU 2001 I replaced engine thermostat it fix all problems with radiator fans.Thermostat has two wires and gives a signal to ECU I guess,and if it's bad it gives a bad signal to ECU that is a reason why radiator fans are always working.Do not change the other sensors and relays for temperature-related.This would solve your problem with Fans.

Why is my 2001 cadillac running hot?


With the thermostat out you should see a lot of circulation. If not investigate water pump. Is the fan electric fan working? Bypass the relay and run the fan whenever the engine is running. If it doesn't overheat with the fan running then investigate fan control. make sure the coolant is topped off and use a thermometer in the radiator to verify temperature.

Fan with burn smell when engine switched off


It is normal for the fan to run for a short while (few minutes) after turning off the car to allow the heat in the radiator to dissipate. The time may be dependent on the coolant temperature or it could just be a fixed time (i.e. so many minutes). The burning smell could be a loose belt, but I suspect the radiator fan is electrical and not belt-driven. I think the burning smell could be oil from a leaking gasket. The oil drips onto the hot engine and voila... burnt oil. Not sure what you mean by new (new to you or 2013-14 model), but new cars should not have any leaking fluids. A stuck break caliper could aslo produce a burning smell.

Check the radiator and the cooling fan. open the hood as the engine temperature rises does the fan come on. if not that the problem, Also do this As the car is warming up(from a cold start) near operating temperature, turn off the car, watch out for the fan, engine of key in your pocket fell the radiator is there any hot or cold spot? if there is the radiator is plugged. Also if the radiator isnt plugged new doesnt mean it works, the water pump itself can be faulty. and dont forget the most important device the Thermostat you did timing belt waterpump they should of done thermostat.

Fan keeps running after car is turned off? Sensor or relay problem??


Some cars are designed to have the fan run for a few minutes after you turn the car off. But if doesn't stop until the battery drains, then it might be a faulty switch or temperature sensor.

Or, if the fan stays running when the engine and radiator are cool you have a very cheap problem: The fan thermostat is stuck closed. A new thermostat will fix the problem--the hardest part of replacing it is finding it. Follow the wires from the fan to the switch--it is usually on the bottom tank of the radiator. Drain the radiator first and save the coolant to put back in after you replace the thermostat. NEVER OPEN A HOT RADIATOR.

If that wasn't it then check the following:
  • Check to see that your coolant level is correct. Top up as necessary.
  • Lay your hand on the radiator (with the engine off) and feel if it is as hot at the top as it is at the bottom. If not, your radiator may be clogged and need flushed or replaced. (Flushing is cheap. Replacing the radiator isn't)
  • Do you get heat from the heater? Leave it turned on high and see if your fan stays running the next time. If it takes care of the problem that could mean you have a kinked radiator hose.

Hope this helped (remember comment and rated this).

REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.CHECK MECHANICAL COOLING FAN.SHOULD HAVE RESISTANCE WHEN TURN WITH HAND.IF FREEWHEELS FAN CLUTCH NEED TO BE REPLACED.CHECK TO MAKE SURE AUXILIARY ELECTRIC COOLING FAN RUNNING HOT WIRE COOLING FAN IF FAN RUNS.YOU HAVE FAULTY THERMO SWITCH LOCATED AT THE BOTTOM OF RADIATOR ON THE LEFT HAND SIDE ON 4 CYLINDER ENGINE FOR V6 ENGINE THERMO SWITCH LOCATED ON THE LOWER RADIATOR HOSE ON THE RIGHT HAND SIDE OF THE ENGINE COMPARTMENT. CHECK FOR BLOWN COOLANT FAN FUSE OR FAULTY RELAY.IF THE AUXILIARY ELECTRIC FAN DONT RUN WHEN HOT WIRED THE ELECTRIC FAN FAULTY.

SOUND LIKE FAULTY CLUTCH FAN OR THE AUXILIARY ELECTRIC COOLANT FAN NOT RUNNING. CHECK AUXILIARY FAN FUSE AND RELAY. IF LOOK GOOD HOT WIRE TO SEE IF FAN TURNS ON IF NOT FAN FAULTY. IF FAN RUNS YOU HAVE FAULTY THERMO SWITCH. WHICH LOCATED AT THE BOTTOM OF RADIATOR ON THE LEFT HAND SIDE OR ON THE LOWER RADIATOR HOSE ON THE RIGHT HAND SIDE OF THE ENGINE COMPARTMENT.IF FANS OKAY COOLANT LEVEL CORRECT.REPLACE THERMOSTAT.HAVE RADIATOR AND ENGINE FLUSHED.CHECK IN FRONT OF GRILLE MAKE SURE NO DEBRIS BLOCKING OFF AIR FLOW THROUGH RADIATOR CORES AND AC CONDENSOR CORES.

Fan runs sometime when the engine is cold and runs down battery


There is a fan switch,,,,sometimes called a sensor which controls the fan....usually located on the back side of the radiator....likely on the left side....about halfway between top and bottom...replace it...Must drain radiator down to that point...Joe LittleBear

Ok well there are two issues here the boiling and the potential for the transmission to be harmed by the contamination of the tranny fluid by antifreeze. First A/T fluid is not going to harm the coolant system in the least, however antifreeze in the trans. fluid will harm the automatic transmission get the tranny flushed as soon as possible , Change out the thermostat then refill radiator using 50% water 50 % antifreeze ( premixed in container) fill radiator then run the car without radiator cap add coolant as needed, put you radiator cap on and wait 5 - 10 minutes until car comes up to operatimg temp. you must observe the engine to make sure the electric radiator fan comes on after the car runs for at least ten minutes if it does not the problem is the usually the radiator fan relay or the fan coolant temperature sensor last in rare cases the fan itself. As for the air bleed usually letting the car run with the radiator cap off for ten to fifteen minutes will do it just make sure you don't remove the radiator cap when the car is hot 2nd degree burns usually hurt.

Overheating


When you mention the radiator having a hot upper in pipe and a cool bottom out pipe tells me that the coolant is not moving around the engine. This could be down to a water pump not working, blocked radiator, thermostat not opening. The bottom hose should be cooler than the top hose but once the engine is up to working temp which is around 85/90 degrees c for an audi the bottom still should be farly hot to touch. Hope this helps
