And not to forget the question of fuel economy. My V6 runs at a more or less constant 95 degs, confirmed by not only the onboard diagnostics but by Torque Pro.

I don't know where is the problem.
I will try to purge again because the last time, I only purged part of the coolant(5 liters). Last edited by Shuriken_57; 23rd May 2021 at 19:11.. |

If so such a difference between yours and mine looks rather weird.

Here is an example of a sequence a few days ago between 77 and 80° while cruising on an A-road (the 6,410 revs was a kick-down in sport mode!). Mind that the mpg (l/100 km) is overstated. In fact I'm doing a 22.6 mpg (12.5 l/100 km) average in the space of 4 years, but Torque Pro can't cope correctly with E85. The rather freezing temperature is a mocked one because of the 24k Ohms resistor which is tricking the ECU to give more fuel and comply with E85 stoechiometric ratio (1:14.7 instead of 1:9.7 for E5).

Not at all. All is 22 year old genuine Rover but the resistors.

With your car's problems it is important that you carry out procedures fully. I recommend that you drain your cooling system completely, including the cylinder block drain plug at the left hand bank, and follow the MG Rover procedure exactly. Dorchester2 has modified his engine so a comparison isn't valid. There's no point in buying E10 fuel Brahim. It isn't going to make your engine run 10 degrees hotter. Simon

We run four V6s here, three are used on a daily basis and all record roughly the same running temperature 92 - 95 degs, run with ACC active. I believe the standard thermostat opening temperature is 88 degs, so I'm quite happy with 92 - 95 especially as several others have confirmed the same sort of results. Keep well |

The reason why I thought you were fuelling with E85 is that you're living in Sweden. But I remember that the price is now less attractive. Anyway why fearing E10? ... I can't understand. But that's another question and I don't want to begin an argument... Keep you safe as well. Always glad to hear of you.
