thanks for the thoughts on this. It never happened before. Oddly, this morning was 21f (-6C) but on Saturday when I went out at almost exactly the same time and the temperature was -0.4f (-18C) it gave no problem at all. I would have thought the -0.4f would have been more likely to trigger an issue. Just shows, cars are human after all I guess!
I'll leave it for now and see if the problem recurs. Maybe its just a one-off. I read this on the ad I was looking at for a thermostat replacement.
"In overheating situations, the Fail-Safe thermostat automatically locks in the open position, delivering maximum coolant to the engine. When standard thermostats fail, they lock in the closed position, prevent coolant flow and possibly cause serious damage to your engine."
It seems odd that standard thermostats would be designed to kill the engine if they fail. Does anyone know anything about this? If they did, I would most definitely replace it!
