Hans sensor saves the day!
Just had a new radiator fitted, drove off from the garage and after 5 minutes noticed the temperature going past 100 which it had never done before, drove for another 5 minutes and it went up to 114 then then the beeper went off, so i pulled car over immediately.
Called the garage and they came with a replacement car so i could continue to work, if i had not had Hans sensor fitted i do not think i would have noticed the normal gauge going up, which i hear is normally too late. I picked the car up 4 hours later and was told it was an air pocket and the sensor was taking the temperature from where there was no coolant, the top, all the coolant was lower down in the engine so it was ok,they read the engine heat with an laser and while the sensor was saying 115 the engine was actually 95 drove it and it has sat at 97 which looks good. Now here where i would like some advice. 1.How and why did that air pocket occur, was it through their negligence or this can happen occasionally? 2.Given what i did above, stopped car immediately, do you think any damage may have been done? which of course the garage is liable for Thanks |

You are unlikely to have suffered any damage.
The temperature reading you have seen is from overheated water which has passed through. If the sensor is dry, then it does not register afaik. The V6 is prone to air locks if filled incorrectly, it has to be done with knowledge and patience or a vacuum filling system. Check you water levels daily. You can get the same results from a leaking thermostat, or from any other leaks, for that matter. |

Thanks kaiser,
These guys only deal with Rovers, Jag, Roll Royce, Bentleys, vintage ones too should they have made this error? |

Hi
Same thing happened to me after a coolant change a couple of years ago. The service carried out by a Rover (plus Jaguar, Volvo etc) garage. Noticed the standard temp guage at 12 o'clock while on a motorway. Luckily was able to pull off the motorway almost immediately. ZT returned to the garage by flat top. There has been no after effects whatsoever luckily. Barry |

As said by my mechanic the gauge going to 12 o clock does not always mean damage has been done |

Clearly, they should not, but s##t happens, as you know. You'll be OK for another fight, so don't worry too much. |
