I think they should have designed the whole thing with an obvious 'stop point' beyond which it will not turn (like all the other cars I've ever had). That way you know whether it's properly on or not.
If you hit the end stop, it's on - if you don't, it's not. No guesswork. |

Also, when the car is moving, is the temperature now stable within about +3˚? Simon

The phone call came in regard to this car couple of days ago, and given the fact it had expelled all of it's coolant over the engine bay, I surmised that the cap was defective, in all probability. The suggestion was to force the fan outputs with T4 ( all three working satisfactorily ) vacuum fill the car with coolant, and fit another cap, which was carried out according to the official MGR technique, and lo and behold all is good again So Chris could have saved a couple of hours labour by not buying a "genuine" cap from a source I'm not going to name At least he had the presence of mind not to refill the coolant (5 litres) lost until the engine had cooled Brian |

I accept Brians stricture regarding the genuine article but in my defence how do you know what is the genuine article? Even cost cant make that a certainty. I am however happy at this moment to accept I must tighten the cap until it stops and try harder to establish genuine articles. With this in view we must remember our cars have been out of production for 15 years with the a diminishing "official" support organisation and the growth of replacement parts of "apparent" similar quality. Its a lottery and in this instance I will hope I have a better chance of winning with the Xpart cap, note better chance not certainty! Thanks to all and hope not to reurn to this subject. Chris S.

In my opinion, the overheating was caused by an air lock. That's what Brian's vacuum refill resolved. The running temperature isn't controlled by how tight or slack the pressure cap may be, nor is it affected by its relief pressure rating, or whether the seals leak or not. Certainly, coolant may be lost if the seals are bad and the coolant gets hot enough, but this isn't a cause and effect. Coolant loss in this way will eventually result in contstant overheating, but changing a bad cap for a good one has no direct effect on the running temperature.

No sweat I didn't take umbrage just stating what I had learned and also interesting the point of Tcuts about an air lock- you learn something new every day. Thanks to you all. Chris S.
