Really? I remember reading it was a bit of a vague measurement but I didn't realise it was as bad as that! |

Hello Andrew, here's a not too steep bit of the learning curve. To check the actual running temperature, you can switch on the Trip Screen Diagnostic system. This allows you to see the temperature changing in real time in degrees Centigrade. It provides lots of other interesting stuff, but the running temperature is what most people use it for. The How To is here: https://www.the75andztclub.co.uk/for...ad.php?t=55585
Concentrate on section 7 for engine temperature. You'll probably need to practice the button presses, but you'll quickly get the hang of it. The diesel ought to run aound 85-90C, but for various reasons, few actually do. If you find your 'normal' running temperature is closer to 75C, you should consider fitting the in-line thermostat modification. It's pretty easy to do and has benefits all round. See this How To: https://www.the75andztclub.co.uk/for...d.php?t=100594 Quote:
https://www.the75andztclub.co.uk/for...ight=jules+fan You could try fitting new brushes or if that isn't possible, a popular fix is to replace the fan conpletely with a second hand 2-speed system or a third party fan kit (Jules sells one). Hope this helps. TC |

I began reading that guide from Jules late last night but my brain was too fried to take it in properly. I plan on reading it properly soon. |

T-Cut,
Thanks for your detailed guide on the diagnostic access. I managed to get the screen I wanted on the second attempt. Much like my drivers licence. Took the car for a 45 minute drive on a variety of roads using all styles of driving...apart from getaway driving and drifting. I'm averaging around 83-85 so not too bad. A nifty on board feature! |

If it doesn't then probably the brush gear is worn. |

Diesel radiator fan check
Quote:
Andrew; with the ignition on or engine running, press the windscreen demist button. Your air conditioning should now activate (identified by the compressor engaging) and your radiator fan should run continuously. Simon

Thanks for your input again, Simon. From doing some reading of the forum before raising my thread, I was aware there might be some different opinions on when the fan is meant to kick in/how it operates etc. I have established though that mine neither kicks in nor operates Perhaps the high speed still works but I need to read the guide on testing that out.

Here's a simplified guide to testing the 3 speed fan.
Things to bear in mind:
The fan systems are quite complex and differ depending upon the engine type. I have a 3 speed system like yours and I renewed the motor brushes a long time ago now and it's been totally reliable. It was then that I investigated the various circuits and I have a file full of technical information on them! The diesel is unusual in that it uses PWM decoding electronics to drive the relays and that in itself can be a source of trouble. If you're technically minded you can restore your fan motor to working order for about £20 by buying a set of brushes from Engineering Carbon Products Ltd. Arctic has posted one of his excellent pictorial guides to the work involved. Simon

I don't know if I would describe myself as technically minded I have fixed a lot of things on my cars from mechanical stuff to the silly stuff like leaking boots but my achilles heel has always been electrical issues and faults. I simply do not understand that side of things and so far have made no effort to understand them. Silly really as cars are full of electrics. |
