Fan problems v6 2.0 petrol
Hello, I have Rover 75 v6 2.0 petrol from 2002.
My fan seems to work at high speed only. Kicking in at ~109, cutting off at ~104. I thought that it is a three speed fan but my control box in the fan assembly has only two relays - a small and a big one. The fan has three wires. The fan assembly doesn't have a resistor. I'm the second owner so only God knows what has been done to it. Am I missing the resistor? Could it be just brushes?

V6 2.0 litre 2002
Thanks for the excellent information Ivan.
Someone has fitted a 2 speed system from an early 1.8 litre car (it doesn't use a resistor) to your V6. However it should work so I think the most likely explanation is that the earth brush has worn down to minimum. If you're handy with a soldering iron you can buy a set of new brushes for £20 (plus postage) which is by far the most economical and satisfactory repair. Let me know if you need further details. Simon

Hello Simon, thank so much for the answer!
I will try to change the brushes. I’m far from Uk so I’ll try to stock them locally. I red that the material is M17 but the internet seems unaware what that means. I have the dimensions so I’ll try to buy bigger once and polish them down to the correct size. A local producer said the brushed for the car industry are normally stiffer and are made from metal-carbon or metal-graphite. I guess I’ll do what I can. |

Looking at this page the M17 doesn’t even exists, so what material did you get it from? |

Yes the motors and motor internals are the same, it's just the relay box that is different
