It's back on the road

Hi folks,

Just a quick thanks to sd1too (Simon) and arctic and to others who have helped me with advice and parts and pictures I've the past few weeks while trying to fix our 75 V6.

Today we got the tyres done and changed the aux belt idler pulley. For those who know about my coolant bleeding woes. I still aren't certain wether I have been able to bleed the system completely but I have been able to drive it and put some miles on it. Hopefully a drive round etc may help move the airlock.
It feels much better on new tyres.
I did also run the diagnostics while driving to show the coolant temp.
Drive along smaller A roads in 0.5 to 1°c so fairly cold outside temperatures the engine coolant temp was showing between 83-85°c mainly between 30-50mph with occasional snow flurries. (These temperatures around normal?)

Thanks again
Rob

Thank you Rob, that's very kind of you.

As for the temperature, I'm not sure. Keep it under observation; the weather's supposed to be getting a bit warmer next week.

Not a problem Simon, but I may need to pick your brains in the future 😅.

I wasn't overly concerned as I know there's coolant in there. I'll keep an eye on levels and temps. What would normal temperature be? I'm sure the stat opens at 82°c.

Thanks
Rob

I've always thought that it's just above the thermostat's opening temperature which is 88°c despite what it says on the plastic housing!

I'll try to remember to check mine when I next use the 75 on a freezing cold day.

Okay so that could also explain low mpg despite really steady driving (around 26mpg). As effectively it could still be on choke?.

If the coolant system needs another bleed attempt, would you recommend looking towards a blocked oil cooler?

Thanks
Rob

My normal running temperature (2.5 V6) is around 94 degs and we haven't seen the temperature over zero for the past 2 weeks.
