VW Polo Classic 1.6 Radiator fan not going on

Good day, I just purchased a VW Polo 1.6 Classic 2002 Model and have the car for 3 months now. On Saturday whilst I was in traffic, I noticed the red light flash on the dashboard, 1 minute later there was steam coming out from the engine where the water bottle is situated. I then managed to get to a garage to fill up the water and coolant level, but noticed that the fan was not going on at all.

I then took it to a mechanic who then suggested we replace the switch, but even that is not working.

What else could be the problem?

Any assistance will be highly appreciated.

Regards

    Mine is a 1.4 W Reg Polo - exactly the same symptoms. the AA had a look and checked the fuse (OK) switch had power going through to it but the fan did not turn. I also had the same problem on a T reg VW Polo a few years ago.

Try moving the fan blades by hand to see if the fan spins freely to see if the problem is frozen bearings in the fan motor. Replace the fan motor if it doesn't turn. If it spins freely disconnect the wires and hook the fan directly to the battery using a jumper. If it runs the problem is most likely the thermostatic switch. If it doesn't the fan motor is bad.

    The relay control for the fan is under the left hand headlight, accesible from under the car, check it for dry solder joints inside, it`s not easy to get out, and you will need to clean the sealer out of the seams to get it apart, and re-seal to put it back together.

Try the changing the thermostat valve, since if valve closed shut there may not be enough circulation to trigger the thermostat switch. Also check if you are losing water at the inside heater radator, which may have a leak. Good luck.

Good day, I purchased a VW Polo 1.6 Classic 2001 Model and have the car for 7 years now. On Saturday whilst I was in traffic, I noticed the brain box, sensor and the key on the dashboard, 1 minute later there was steam coming out from the engine where the water bottle is situated. I then managed to get to a garage to fill up the water and coolant level, but noticed that the fan was not going on at all.

I then took it to a mechanic who then suggested we replace the switch, but even that is not working. I base in Nigeria. (Email me: Vic_musof@yahoo.co.uk)

My dash cluster isnt working on 97 polo,indicators,do work

Try replacing the thermostat as sometimes it will not compress to let hot water through to the switch to let the radiator fans know that they must start operating.

Overheating Polo


this sounds like a thermostat fault, but also could be the sensor switch to the radiator but is more likely the thermostat, it should be located at the front top of engine, follow the top water hose to the engine and you will find the thermostat housing, also just a heads up, these had a problem when first made, according to the known fixes and problems with VW's the hoses corroded inside and started loosing water, this could be wise to get the system presure checked to...hope this helps

I take it you have the radiator full and the drive belts properly tensioned.
Here is the ordered check list;
1) Get the error codes read-out. Many chain auto part stores will loan a meter to get this for free. Call. They may be mis-leading because of other problems, but may still be useful.
2) Check the fuses
3) If the radiator fan is not running while the car is hot you may need to check the thermal switch. This switch will turn on the radiator fan. If the connection to the switch was good, you may need to replace the switch. I believe the switch is in the lower section of the radiator with wires connected to it.
4) Check the thermostat and its housing for damage. Water has to flow through it.

I believe the temperature sensor that you see displayed on the dash is located on the engine near the heater hose. if everything else checks ok you may check this for false readings.

The problem should be corrected for the temperature sensor. The engine can be in hot/cold start mode and Lambda probe would get the wrong info.

Fan fuse keeps burning out


I would think the fan motor is drawing too much current, causing the fuse housing to melt.
