The instrument panel coolant temperature gauge lies like a politician. It will point at nominal from around an ECT sensor reading of 50°C (122°F) as shown by running the car with the dash in test mode or monitoring via an accessport or scan tool. The gauge position vs temperature is shown via the i.p. screen. So no neither the oil or coolant warm up quickly in this weather.My coolant comes up very quickly - although I think the jury is out as to whether the gauge is lying or not. I've heard some people comment on that. The oil is what takes ages to warm up. And yeah, the block heater would be good, but it's likely to be the kind of thing I'm not going to screw with every night and every morning - I had it in the SVT, used it a couple times, and then quit because it was just a hassle.
