[A4] Strange cooling behavior at 0F ambient

[rocketscienceracing at comcast.net]

As some of us have no doubt noticed, the last week or so saw some 0 to -10F weather here in the Northeast. Nothing compared to certain other climes, but my 98A41.8 sure acted funny.

At those temperatures the coolant temperature guage, normally rock solid straight up (half way) once the engine is fully up to temperature, would not rise above 1/4 up. It was almost as if I had a stuck thermostat. I say almost because engine temperature did not vary with speed. Now that the temps have returned to above 0F it is acting normally again.

So, is this normal? Anyone else experience this?

Thanks,

Scott
