Thanks. Yes, bigger engines make more heat. Ambient temp and longer trips make a big difference too. My regular commute is 4 miles. Around freezing its up to temp in a couple of miles and I usually turn the heater on then. When it was -15/-20F, I had to turn on the heater after the first mile or two but it never got quite warm enough to open the thermostat. Shorter commutes with the family were worse since I needed the heater on right away. Its's good around town as is to about 50F but warmer than that and I will need to open things up some. Insulating the coolant hoses might be worth a try. I wish I had a garage for winter. The wheel bearings get so stiff in the cold it feels like the brakes are dragging.
