Aaron, If yours is an early MGB with its temperature probe in the upper
radiator tank, being a bit low on coolant can affect the reading as the probe
must be in the liquid. Later cars have the electric sender in the head, so
being a pint low is unlikely to affect the reading on the gauge.Bob

the stat will be fully open anyway regardless of its value.
Eep! So it's not the thermostat after all.
I pulled it tonight and it says "88*" on the side. Since it's a german
brand,
I assumed 88C, which is 190F. Using the pan-o-water testing method, I
verified it opened at 86C and closed correctly too.
I noted that when I put the coolant back in, it wasn't quite reaching the top
of the core, so I added some more. Maybe a pint, probably less. Would this
be enough to cause erratic readings? I'll be doing the "drive some, stop and
check temp, drive some more, repeat" process soon enough. Glad I have that
infrared thermometer!
