Yes I have my 1.8t but a friend who is new to discover these great cars got himself a lovely Wedgewood 2.5 auto with Neptune leather. Just ironing out some foibles and bits, as I have never really touched the V6s before. Having done a little research and what Trikey says, I have advised he needs to go for the uprated fan which is available on ebay from 75ztspecialist? Thanks for the advice |

David; I would like you to perform the test I listed because your evidence doesn't point immediately to a straightforward diagnosis. Your friend should not buy anything yet as there is a risk that he could waste his time and money. The cheapest and most reliable solution is to repair the original fan system. Ebay fans will not be "uprated". If a replacement is proven to be necessary, and we don't know that yet, I'd strongly recommend that you take the advice of club members Arctic and Jules.
Simon

My friend did this today and says when he pressed Demist the fan did not operate. The interior dual zone controls were set to 27 if that would alter anything? |

No the fan should kick in straight away regardless the tempreture so i do suspect a fan failure

So your friend's V6 has two problems: an air lock and loss of the low speed radiator fan. Is he also based in Bromley? Will he be repairing it himself? Will you be doing it for him? If he wants to pay someone, I strongly recommend not taking it to a local garage. Instead, contact club trader cb750Chris who is based in Portsmouth and doesn't mind travelling. Tips:
I've done both these jobs on my V6 so can provide further detail if it would help. Simon

If the fan motor brushes had failed and or worn out, surely that would render the fan motor inoperable? Thanks for the advice |

The windscreen demist button test proves that the fan does not work when air conditioning is requested. Don't rely on auto mode for a diagnosis. Quote:

That’s all great info and really helpful.
If he wants to refurb the existing fan motor, which is the best replacement brushes, and where can they he obtained? I’ll probably end up doing the motor brushes for him. If CB750 can contact me and maybe if he is willing to come to Bromley he could help out? Thanks |

You might like to have a look at Arctic's many helpful photographs of what to expect when you remove the motor end cap. Do the job sooner rather than later as every time the motor runs you're risking the worn brush popping out of its holder and damaging the commutator beyond repair. Here's the recommended MGR procedure for bleeding the cooling system of air. Simon

Superb, thank you!
That company is only a few miles away so will probably go and get the bits asap. Any words of warning for doing the brushes? Do you think having the car run up to 112 a few times now will have caused any issues on a KV6? As you know I’m a 4 pot guy. |
