Is this the radiator cooling fan? They have had two recalls on the cooling fan controller.

It just started this then it could be the motor burning out on the fans because their electric fans. or a sensor. you need to take it to someone with a code reader and they can tell you exactly whats happening.

There is an open recall out for the 2003 Mitsubishi outlander. It's for te engine cooling fan to be replaced. Just call your local mitsubishi dealership and schedule to bring it in, it's free. It's been an open recall since 2008. I just bought mine and I'm taking it in tomorrow.

How do you fix radiator fans

First go to an auto parts store that offers free scans to see if any codes are set.

The fan is controlled by the computer which gets inputs from sensors. Could be a bad sensor or a wiring problem.

Has any work been done recently?

Hi I have a 2003 mitsubishi outlander with an overheating problem.I understand that there was a recall to replace the cooling fan controller.We are now in 2011 do I still qualify for the recall to...

I had the exact same problem with my 03' Outlander. I called the dealer and gave them the last 8 digits of the VIN and found that my Outlander had "no outstanding recalls". Tough luck. Apparently, the recall/repair was done a few years ago by the previous owner and now its acting up again.
Well, have no fear, the problem is caused by a defective cooling fan controller which is located on the inside wall of the radiator. You cant miss it. Disconnect the plug thats attached to the input of the controller (it comes from the ECU in the fuse box on the drivers side engine compartment). Check for 12VDC coming into the unit from the ECU to make sure its got voltage when the engine is running with the AC on. If it does, and the fans are not running, the unit is most likely the problem. You can also check the two outputs to the two fans for 12vdc to make sure the fans arent both bad. (unlikely)

Give the unit a tap with a wrench with the AC on and engine running (be careful) to see if the relays free up and the fans start running. It worked on mine! Now the car runs cool as a cucumber even at long red lights and in traffic jams. Sometimes the relays can get stuck. I hope this helps.

Why there are 02 fans near radiator? What are the purposes? One is working and one is not.

Hi and welcome to FixYa I am Kelly.
You have 2 fans because one is the temperature controlled radiator fan that only runs when the engine water temp is above 160 deg. F. The water termperature controlled fan can run even with the ignition key OFF should the Engine water temp be too hot.
The 2nd fan is for your Air-Conditioner that should run when the cabin temp is set low enough for the Air-Conditioner compressor to run. This fan should run anytime the Air-Conditoner is switched on.
If your experiencing engine over heat problems when driving slow or sitting idle most likely the fan switch that is switched on by water temperature has failed. The fan switch controls a fan relay and if the relay fails the fan will not run. In this particular model there is a cooling fan module that controls the fan.

Noise from engine, oil indication on , before one year change balance shaft and bearings on mitsubishi outlander year 2004,4x4,suspect the same problem now?

do not run engine with red oil light on, it can cause severe damage. Check oil level first. If ok, then check oil pressure with a gauge. If oil is not low, you may have a clogged filter or a borlen oil pump inside the engine.

When sitting at light car runs hot, when moving car stop running hot

At idle, with engine hot, is the fan blade turning?

Theory is, at idle, need the fan to pull air though the radiator, at highway speeds, the air flows through without need for the fan.

2003 mitsubishi outlander fan keeps coming on the lights dim also when driving fan keeps coming on the lights dim also when driving. radiator is full and it starts within minutes of starting the car.

My blower fan will run with the key out, but will turn of with the fan switch. I changed the A/C relay under the dash and it seem to fix the problem.
