If there is a fault here would this be concidered "overcooling"?

Would it coincide with me noticing a slight dip in mpg this week?
more than likely it would  :wink: if its taking about 10 miles to get to 90 i would say that its your thermostat

Yes all the themostat does is stop the water getting to the radiator until it reaches a certain temperature if it opens too soon or indeed if its open all the time then the warm water will get cooled in the radiator and take for ever to heat up. You will use more fuel while the engine stays cold like being on choke but should be ok once hot.

Journey to work it took 10 mins to warm up, journey home it was fine again!   :angry:

I've ordered the thermostat, o-ring and will get fresh coolant.  I was at a loose end this weekend anyways!

Cracks knuckles.....

Thermostat done today with big help from TJG!

Seems fine now, will have to keep an eye on coolant level for next little while is all.

Went out this morning before fitting it and still took ages.  New thermostat and replaced coolant and 90° reached in proper time again.

Easy enough, just a bit fiddly.

Great!

Highlights being some tw@ almost driving over me, or losing that bolt in the deep dark recesses of the engine bay?   :grin:
