Right guys, well I think in light of the advice I've received, it would be best to first sort out the resistor and hopefully that solves the problem. If not then I'll have a look into the thermostat replacement.
Regarding the firing on all cylinders issue, I'll make a note of the aforementioned possible causes of the problem and talk to my mechanic. I'll be back in touch with everyone on the thread as soon as. In the meanwhile, thank you all so much for the help and support |

Hi everyone,
I'm thinking now of replacing my 75 with an identical 75, however, this one is a year newer (2005) with 34000 mileage. I understand that in older models the head gasket was an issue, comments have been made that head gaskets go every 35-40k miles. Did that issue ever get fixed by the manufacturer for the newer models. My concern is that are we going to face another head gasket issue in the future with the newer 75 that I am looking into. Please reply ASAP Cheers. |

Ten days ago you were going to renew your fan resistor. What's happened with that? Has someone told you that your head gasket has gone?
A newer car, with lower mileage, is not necessarily going to be more reliable. The head gasket on any engine, but particularly on the 1.8, will fail if the cooling system is neglected. There is no fixed mileage interval; some owners have never had a failure. The manufacturer produced an uprated MLS gasket for the 1.8, but it is not a magic cure in itself. Other factors have to be taken into consideration which you can read about on this forum. So, if you're thinking that changing the car is going to solve all your problems, think again would be my advice. Simon

Take a step back Simon, the demist test, would it not all depend on what the mechanic had done to create the switch on the dash? If he has bypassed and isolated the normal fan control creating a power source for the fan via the dash switch then the demist test is going to be academic.
Mohammed, I have to agree with Simon (SD1too) about replacing the car. You know the problems with the car you have and through this forum you are getting solutions to them. Buy another car chances are you will face problems with it as well. Head gaskets, if they have been replaced how long they last depends a lot on the quality of the work done. Low mileage doesn't automatically equate to a better car, it all depends on how it has been looked after. One thing I would suggest is get the car to someone who knows the cars, the fact your mechanic hasn't cured the overheating, merely side stepped it by bypassed the fan controls suggests he doesn't.

The normal fan control involves relays. To by-pass and isolate those would mean using cables and a switch capable of handling 30 amps continuously. I was satisfied that this would not be the case. My guess is that the mechanic has wired the switch to energise the fast speed relay coil, and in that event I concluded that the demist test was still valid. However I agree that it's possible that the mechanic has done something unpredictable. Ideally the modifications need to be removed and the circuit returned to normal, and the OP can always instruct his garage to do this. The alternative I suppose is to take the car to a local meeting for some dismantling and investigation to take place. I think there's one scheduled soon just off the M25 at Leatherhead which should be convenient. Simon
