Fan does not operate in econ mode.

Allow for the ambient temperature when referring monitoring the coolant temp. as Kaiser says above. I doubted him a few years ago, but he was correct (and proved now after 3 winters).

What did make a difference in colder weather, was driving style (not to mention distance). If I drove hard, it would warm up at the same rate as during the summer driving normally. Driving normally, it didn't actually reach opening temp after my 10 mile commute. (Mine is a diesel, but the laws of thermodynamics and meteorology will still apply to petrol engines, it will just have a different variance over 'normal' ). Having the heater on too will lengthen the warm up time also, as will storing over night in a garage or on the street.
