MetroMPG.com mailbag: Metro engine won't stay warm in super cold weather

This isn't the first time I've heard this story about the little 993cc motors in these cars in extremely cold conditions ... (like -20 C / -4 F and below):

Quote:
It's been real cold lately and driving the Geo is just brutal in this weather. I have a piece of cardboard covering 100% of the front of the radiator yet the engine still dislikes warming up (and even reaching a warm state, the temperature gauge will slide all the way back to the "C" mark if left idling).

I was talking with a guy today and he said that there's probably something wrong with my thermostat as he believes that the coolant in my car shouldn't circulate at all until a certain temperature is met.

Is this true with the Fireflys/Metros?
Feel free to jump in with other diagnoses & suggestions, but here's my reply...
