They fixed a leak from the straight plastic pipe and during this I think they used some sort of rad seal. A few days later I checked in my expansion tank and saw tiny glittery bits floating around in there, that were NOT there before I took it in. I took it back and questioned him and he said he didn't use any sort or rad seal. He has always been honest before, have used him for years. Not wanting an argument, I asked him to empty the coolant, flush out my matrix and refill with new coolant. He done this according to him. The coolant was definitely changed as I inspected it. It's since then I have noticed the above problem. I assumed an air lock of sorts. I may ask to have another empty, flush, refill cycle but need to find a mechanic that is savvy with rover kv6 procedures. I'm not concerned with the stat. It had a new one 9 months ago, and my car has always run at 81° since I bought it a year ago. I've become so hung up on it overheating I fitted an one reader so I know it's accurate. I learnt within weeks of owning the car to ignore the dash temp gauge |

Just a couple of pointers from me besides an airlock.
If you suspect that some sort of radweld was used the Rover 75 heater matrix is known to be prone to blockages so one thing to check is have your heat on and feel with your hand then temperature of the air and move from the drivers side to the passengers If the air is getting progressively colder towards the passenger side your heater matrix will most likely be blocked. Also I'll agree with Simon your car seems to be running cold it should be around 95C° I've had a similar problem and I think a few members of the forum have pointed out that replacement thermostats as of late seem to make cars run cold. I went through 3 thermostat last year because I had a cold running issue. The second one made my car run at about 78-82C° similar to yours and my heater performance was appalling.

You're quite right about the new thermostats. Mat confirmed that he can't get hold of the original spec 88 deg ones, and only has the cooler ones now. I've got an order in with him at the moment for a set of new O rings for the thermostat system and have removed a genuine 88 deg used thermostat from my donor rather than buy one of these low temperature ones.
It might not matter too much in the UK climate but here a low temperature thermostat is for summer use only. Actually the O rings from the donor thermostat looked like new, not compressed and I could probably have reused them. Regards |

Traffic here in great Yarmouth is dreadful at 9 and 16:00, and if I was driving my 75 at around 95, it would continuously be tripping the cooling fan when I stop at lights. I've learnt this isn't really the car to be sitting in traffic with. |

I have tested it with the onboard diagnostic setting (19/7) and it is identical. I understand the OBD reader just replicates what is being read by the instrument pack anyway. |

If you're sitting in traffic and the temp starts rising, press the demist button, it turns the fan on Have a look for a digital temp guage, a chap called Harry used to sell them on ebay Here's mine

Yeah I use that trick all the while, and I have an OBD reader permanently attached and on my dashboard so I can always see my ECT. It's crazy how quick it goes from 82 to 90 when just stopping at lights.

Likewise the 'econ' button does the same without redirecting the air to the vents.
